Abstract
Unprecedented interheteromacrocyclic hosts charge transfer (CT) crystals were generated by cooling organic solutions containing p-dimethoxybenzene-constituted pillar[5]arene (P5A) and p-benzoquinone-constituted pillar[5]quinone (P5Q). Despite the weak CT interaction known between p-dimethoxybenzene and p-benzoquinone and the lack of formation of CT complexes between P5A and P5Q in the solution phase, CT cocrystals between P5A and P5Q were formed with solvent molecules included into the hosts' cavities. Such a cocrystallization arises from an elegant synergy between the CT interaction and solvent-binding-promoted crystallization. The interhetero hosts CT crystals were studied by optical and electron microscopic techniques, X-ray powder diffraction, solid-state NMR, UV-vis, IR spectroscopic studies, and X-ray single-crystal studies. The solvent complexation was critical for formation of the supramolecular CT microcrystals. The CT absorption bands faded upon removing the solvent molecules under vacuum, but they could be recovered by reuptake of the solvent molecules. Intriguingly, the CT absorption bands and uptake kinetics are distinguishably different for various organic solvents, thus providing a unique way to distinguish between different commonly used chemicals.

Abstract
Stilbene derivatives have long been known to undergo “acid-catalyzed” Z → E isomerization, where a strong mineral acid at high concentration is practically necessary. Such severe reaction conditions often cause undesired by-reactions and limit their potential application. Herein, we present a trace mild acid-catalyzed Z → E isomerization found with stilbene derivatives fused with a norbornene moiety. By-reactions, such as the migration of the C

]]>
C double bond and electrophilic addition reactions, were completely inhibited because of the ring strain caused by the fused norbornene component. Direct photolysis of the E isomers at selected wavelengths led to the E → Z photoisomerization of these stilbene derivatives and thus constituted a unique class of molecular switches orthogonally controllable by light and acid. The catalytic amount of acid could be readily removed, and the Z → E isomerization could be controlled by turning on/off the irradiation of a photoacid, which allowed repeated isomerization in a non-invasive manner. Moreover, the Z isomer produced by photoisomerization could spontaneously self-recover to the E isomer in the presence of a catalytic amount of acid. The kinetics of Z → E isomerization were adjustable by manipulating catalytic factors and, therefore, unprecedented molecular photoswitches with adjustable self-recovery were realized. Quantitative Z → E isomerization was catalyzed by trace mild acids to offer molecular switches orthogonally controllable by acid and light.![]()

Multiple Stimuli-Responsive Conformational Exchanges of Biphen[3]arene Macrocycle. Molecules 2020; 25:molecules25245780.

Abstract
Conformational exchanges of synthetic macrocyclic acceptors are rather fast, which is rarely studied in the absence of guests. Here, we report multiple stimuli-responsive conformational exchanges between two preexisting conformations of 2,2',4,4'-tetramethoxyl biphen[3]arene (MeBP3) macrocycle. Structures of these two conformations are both observed in solid state, and characterized by 1H NMR, 13C NMR and 2D NMR in solution. In particular, conformational exchanges can respond to solvents, temperatures, guest binding and acid/base addition. The current system may have a role to play in the construction of molecular switches and other stimuli-responsive systems.

Abstract
With the rapid progress of nanotechnology, near-infrared (NIR), light-assisted phototherapy as a minimally invasive local cancer therapy, especially photothermal therapy (PTT), has captured broad research attention in recent years. However, combined target molecules with a PTT system through reversible supramolecular interactions has been reported rarely. In this work, we constructed a supramolecular nanosystem combining ATP capture and target PTT based on cationic pillar[5]arene (CWP5)-functionalized Cu2-xSe nanoparticles (Cu2-xSe@CWP5 NPs). Cu2-xSe@CWP5 NPs, with an average diameter of approximately 100 nm and strong absorption in the near-infrared-II window, were prepared in water through a facile one-step in situ synthesis method, then (4-carboxybutyl)triphenylphosphonium bromide (TPP), a mitochondria-targeted molecule, was modified on the surface of the particles through the host-guest recognition. Upon irradiation with a 1064 nm laser, the obtained Cu2-xSe@CWP5/TPP NPs showed remarkably photothermal ablation capability to HeLa cells. Importantly, our Cu2-xSe@CWP5/TPP NPs exhibited excellent therapeutic effect due to the combination of inhibited hydrolysis of ATP and targeted photothermal therapy upon in vitro and in vivo studies. Significantly, through host-guest interactions, we can modify different types of target molecules within this PTT system at will.

Abstract
![]()
To
investigate the dynamic stereochemical inversion behavior of
pillar[5]arenes (P[5]s) in more detail, we synthesized a series of
novel rim-differentiated P[5]s with various substituents and examined
their rapid rotations by variable-temperature NMR (203–298
K). These studies revealed for the first time the barrier of “methyl-through-the-annulus”
rotation (ΔG‡ = 47.4 kJ·mol–1 in acetone) and indicated that for rim-differentiated
P[5]s with two types of alkyl substituents, the smaller rim typically
determines the rate of rotation. However, substituents with terminal
C=C or C≡C bonds give rise to lower inversion barriers,
presumably as a result of attractive π–π interactions
in the transition state. Finally, data on a rim-differentiated penta-methyl-penta-propargyl
P[5] exhibited the complexity of the overall inversion dynamics.

Abstract
The competitive conformation chirality of dynamically racemic water-soluble pillar[5]arene WP5 can be induced by 19 different l-amino acid ethyl ester hydrochlorides. Among them, l-Arg-OEt and 18 other l-amino acid ethyl ester hydrochlorides can induce the opposite-handedness conformation of WP5. This was ascribed to the different binding models with a side-chain moiety or ethyl ester moiety of amino acids toward the cavity of WP5.

Abstract
We report a solvent-dependent switching and holding of planar chirality of pillar[5]arene with stereogenic carbons at both rims by host-guest complexation with achiral guest solvents. The planar chirality could be held for a given length of time at 25 °C in long linear guest solvents by kinetic trapping through host-guest complexation. The kinetic trapping worked at 25 °C, but not at 60 °C, thus a planar-chiral inversion using kinetic trapping based on host-guest complexation in the long linear solvents was demonstrated.
