Abstract
A quinoxaline-fused octaphyrin(2.0.0.0.2.0.0.0) was synthesized by the FeCl3-induced oxidative coupling of an α-free quinoxaline-fused tetrapyrrole. This macrocycle adopts a figure-of-eight conformation in the solid state and acts as a rudimentary chemosensor in solution. The Lewis basic anions fluoride and hydroxide induce a colour change via a deprotonation mechanism.

Abstract
![]()
Hydrogen-bonding
interactions have been explored in catalysis,
enabling complex chemical reactions. Recently, enantioselective nucleophilic
fluorination with metal alkali fluoride has been accomplished with
BINAM-derived bisurea catalysts, presenting up to four NH hydrogen-bond
donors (HBDs) for fluoride. These catalysts bring insoluble CsF and
KF into solution, control fluoride nucleophilicity, and provide a
chiral microenvironment for enantioselective fluoride delivery to
the electrophile. These attributes encouraged a 1H/19F NMR study to gain information on hydrogen-bonding networks
with fluoride in solution, as well as how these arrangements impact
the efficiency of catalytic nucleophilic fluorination. Herein, NMR
experiments enabled the determination of the number and magnitude
of HB contacts to fluoride for thirteen bisurea catalysts. These data
supplemented by diagnostic coupling constants 1hJNH···F– give
insight into how multiple H bonds to fluoride influence reaction performance.
In dichloromethane (DCM-d2), nonalkylated
BINAM-derived bisurea catalyst engages two of its four NH groups in
hydrogen bonding with fluoride, an arrangement that allows effective
phase-transfer capability but low control over enantioselectivity
for fluoride delivery. The more efficient N-alkylated BINAM-derived
bisurea catalysts undergo urea isomerization upon fluoride binding
and form dynamically rigid trifurcated hydrogen-bonded fluoride complexes
that are structurally similar to their conformation in the solid state.
Insight into how the countercation influences fluoride complexation
is provided based on NMR data characterizing the species formed in
DCM-d2 when reacting a bisurea catalyst
with tetra-n-butylammonium fluoride (TBAF) or CsF.
Structure–activity analysis reveals that the three hydrogen-bond
contacts with fluoride are not equal in terms of their contribution
to catalyst efficacy, suggesting that tuning individual electronic
environment is a viable approach to control phase-transfer ability
and enantioselectivity.

Abstract
![]()
Covalent
macrocycles and three-dimensional cages were prepared by the self-assembly
of di- or tritopic anilines and 2,6-diformylpyridine subcomponents
around palladium(II) templates. The resulting 2,6-bis(imino)pyridyl-PdII motif contains a tridentate ligand, leaving a free coordination
site on the PdII centers, which points inward. The binding
of ligands to the free coordination sites in these assemblies was
found to alter the product stability, and multitopic ligands could
be used to control product size. Multitopic ligands also bridged metallomacrocycles
to form higher-order supramolecular assemblies, which were characterized
via NMR spectroscopy, mass spectrometry, and X-ray crystallography.
An efficient method was developed to reduce the imine bonds to secondary
amines, leading to fully organic covalent macrocycles and cages that
were inaccessible through other means.

Abstract
The bioinspired design and synthesis of building blocks and their assemblies by the supramolecular approach has ever fascinated scientists to utilize such artificial systems for numerous purposes. Flexibility is a basic feature of natural systems. However, in artificial systems this is difficult to control, especially if there is no preorganization of the component(s) of a system. We have designed and synthesized a series of C3 -symmetric N-bridged flexible receptors and successfully utilized them to selectively entrap the notorious and toxic nitrate anion in aqueous medium. This was the first report of highest binding affinity for the nitrate anion in aqueous medium. An impressive self-sorting phenomenon of reversibly formed hydrogen-bonded capsules, which self-assembled from flexible tripodal receptors having branches of similar size and bearing the same amide functionality, has been disclosed. Encapsulated nitrate anion has been further utilized for the photochemical [2+2] cycloaddition reaction for the synthesis of strained four-membered ring structures through dynamic self-assembly. In this Personal Account, we summarize these results showing the utility of naturally inspired flexibility in artificial systems.

Abstract
Bis-ureidoquinoline shows a characteristic UV-vis absorbance and turn-on fluorescence changes in the presence of the fluoride anion. Such selective changes probably originate from the hydrogen-bond interactions, as shown by the (1)H NMR titration and DFT calculations. Bis-ureidoquinoline can be used as a fluoride-selective sensor for the detection of fluoride anions under illumination from a laboratory hand-held UV lamp.

Abstract
Three ferrocenyl-functionalized tripodal hexaurea anion receptors with ortho- (L(2)), meta- (L(3)), and para-phenylene (L(4)) bridges, which showed strong binding affinities toward sulfate ions, have been designed and synthesized. In particular, meta-phenylene-bridged ligand L(3), owing to its trigonal bipyramidal structure, can encapsulate two SO4(2-) ions in its "inner" and "outer" tripodal clefts, respectively, as supported by their clearly distinct NMR resonances and by molecular modeling. The sulfate complex of ortho-ligand L(2), (TBA)2[SO4⊂L(2)]·2H2O (1), displays a caged tetrahedral structure with an encapsulated sulfate ion that is hydrogen bonded by the six urea groups of ligand L(2). CV studies showed two types of electrochemical response of the ferrocene/ferrocenium redox couple upon anion binding, that is, a shift of the wave and the appearance of a new peak. Quantitative binding data were obtained from the NMR and CV titrations.

Abstract
The fluoride anion has recently gained well deserved attention among the scientific community for its importance in many fields of human activities, but also for concerns on its effect on health and the environment. Although surprisingly overlooked in systematic studies in the past, fluoride has nowadays become a topical target in the field of anion recognition. A multitude of scientific reports are published every year where the establishment of efficient and specific interaction with fluoride is sought in polar and aqueous media. Here, the emphasis is directed to a detailed description of the most interesting contemporary studies in the field, with a particular focus given to those published in the last few years.

Abstract
We present an unprecedented fluoride-water cyclic cluster of [F(H(2)O)](4)(4-) assembled in a cuboid molecular box formed by two large macrocycles. Structural characterization reveals that [F(H(2)O)](4)(4-) is assembled by strong H-bonding interactions [OH···F = 2.684(3)-2.724(3) Å], where a fluoride anion plays the topological role of a water molecule in the classical cyclic water octamer. The interaction of fluoride was further confirmed by (19)F NMR and (1)H NMR spectroscopies, indicating the encapsulation of the anionic species within the cavity in solution. High-level DFT calculations and Bader topological analyses fully support the crystallographic results, demonstrating that the bonding arrangement in the fluoride-water cluster arises from the unique geometry of the host.

Abstract
A series of neutral C(3)-symmetric acyclic artificial receptors incorporating amide functionality has been designed, synthesized, and fully characterized. Upon protonation, these conformationally flexible N-bridged tripodal podands 1-5 form in situ cone shape conformation through hydrogen bonding and C-H···π interactions. The protonation-induced interior preorganized cavity is capable of entrapping nitrate anions through the amide N-H bonds to form discrete nitrate complexes (1a-5a), which were fully characterized by NMR, HRESI mass spectra, and single crystal structures. By incorporating suitable fluorophores at each branch of the tripod receptor, the resulting fluorescent receptor 5 selectively recognized nitrate anions by fluorescent quenching in a DMSO solution and displayed one of the highest binding affinities for nitrate anions reported so far in polar media. Receptor 5 represents a unique example of a neutral receptor for the recognition of nitrate anions in polar solvent media by its zwitterionic form. The possible mechanism of proton-induced preorganization of these flexible, acyclic receptors in a convergent cone conformation followed by nitrate complexation has been proposed to rationalize the effective nitrate recognition.

Abstract
The design of supramolecular hosts for anions began with simple diaza bicycles, named katapinands, and has evolved over the last 40 years to a number of elegantly designed receptors capable of binding many different anions. About the same time the term cryptand appeared in reference to another bicyclic compound that was selective for alkaline-earth ions. Since the first report these simple bicycles, a vast arena of hosts has appeared, including acyclic, monocyclic, and other multicyclic supramolecular receptors. Studies of these systems have revealed considerable information about anion coordination chemistry, including the fact that many of these complexes mimic their transition-metal corollaries in terms of coordination numbers. However, for anions interactions occur via H-bonding most often, rather than the coordinate covalent or dative bonds observed in transition-metal coordination. This critical review examines the design of enclosed, primarily bicyclic cryptands as hosts for anions, with a small scattering of higher polyhedra when deemed appropriate to the discussion. In order to show the development (evolution) of the field, key examples of early work will be noted and compared with more recent developments (136 references).

Abstract
This critical review describes selected examples extracted from the extensive literature generated during the past 42 years on the topic of anion binding in molecular capsules. The goal of including anions in molecular capsules emerges from the idea of incorporating the traits exhibited by biological receptors into synthetic ones. At the outset of this research area the capsules were unimolecular. The scaffold of the receptor was designed to covalently link a series of functional groups that could converge into a cavity and to avoid its collapse. The initial examples involved the encapsulation of one monoatomic spherical anion. With time, the cavity size of the receptor was increased and encapsulation of polyatomic anions and co-encapsulation became a reality. Synthetic economy fueled the use of aggregates of self-complementary molecules rather than one large molecule as capsules. The main purpose of this review is to give a general overview of the topic which might be of interest to supramolecular or non supramolecular chemists alike (149 references).

Abstract
An anthracene-based tripodal ligand was synthesized from the condensation of tren with 9-anthraldehyde, and the subsequent reduction with sodium borohydride. The neutral ligand was protonated from the reaction with p-toluenesulfonic acid to give a triply charged chemosensor that was examined for its anion binding ability toward fluoride, chloride, bromide, sulfate and nitrate by the fluorescence spectroscopy in DMSO. The addition of an anion to the ligand resulted in an enhancement in fluorescence intensity at the excitation of 310 nm. Analysis of the spectral changes suggested that the ligand formed a 1:1 complex with each of the anions, showing strong affinity for fluoride and sulfate in DMSO. The unsubstituted tren was reacted with sulfuric acid to form a sulfate complex and the structure was determined by the X-ray crystallography. Analysis of the complex revealed that three sulfates are held between two ligands by multiple hydrogen bonding interactions with protonated amines.
