Abstract
Self-assembly exploits noncovalent interaction to offer an effective method for the fabrication of materials. For Na9 [EuW10 O36 ] ⋅ 32H2 O (EuW10 ), the negative charges and abundant oxygen atoms on its surface provide a handle for static self-assembly. New properties are envisioned for EuW10 aggregates which are able to display such kinetics and time-programming characteristics, in order to satisfy more complex and intelligent application scenarios, such as DNA binding and information encryption. In this work, EuW10 coupling with stimuli-responsive dodecyl dimethylamine oxide (C12 DMAO) can generate versatile aggregates with pH-responsive properties. We demonstrated the temporal programming of the assembly and disassembly of EuW10 nanospheres using a pH clock reaction of acid/urease hydrolysis. The pH clock reaction endows EuW10 assemblies with dynamical properties, in which the charges and fluorescence changes are coded in this system. These fluorescent assemblies provide new application in time-programmed DNA capture and information encryption.

A sustainable luminescence-enhanced tri-assembly of polyoxometalate-peptide-polyamine developed for ultrasensitive spermine determination and discrimination. Colloids Surf B Biointerfaces 2022; 212:112379. [PMID: 35123197 DOI: 10.1016/j.colsurfb.2022.112379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 01/27/2022] [Accepted: 01/28/2022] [Indexed: 11/22/2022]
Abstract
A supramolecular strategy with sustainable emission amplification of an environmentally sensitive polyoxometalate, Na9[EuW10O36]·32H2O (EuW10), has been constructed for the Spm determination and discrimination. The EuW10 has no response to Put and other biogenic amine but a sensitive response to Spm (LOD = 0.56 nM) and Spd (LOD = 85.93 nM), respectively. Assembling with a cationic peptide from HPV E6, GL-22, achieved the EuW10/GL-22 assembly, which showed a unique enhanced emission response to Spm and distinguished it from Spd successfully. Furthermore, a synergistic rather than competitive binding of Spm to the EuW10/GL-22 assembly was revealed using FT-IR, and NMR titration spectra, together with DLS and TEM, essentially for the three-component sensing system. Besides, both EuW10 and EuW10/GL-22 assembly were successfully applied to the Spm determination in human urine and serum, suggesting the potential of these sensing approaches in detecting trace amounts of Spm in the clinic. Therefore, the constructed supramolecular assembly can detect the Spm sensitively (LOD = 2.0 nM) and efficiently distinguish it step-wise from other biogenic amines. It is a facile, straightforward, sensitive, and selective strategy for Spm determination and discrimination, which will be helpful in addressing the related biological and clinical requirements.

Abstract
Supramolecular gels are important soft materials with various applications, which are fabricated through hydrogen bonding, π-π stacking, electrostatic or host-guest interactions. Introducing functional groups, especially inorganic components, is an efficient strategy to obtain gels with robust architecture and high performance. Polyoxometalates (POMs), as a class of negatively-charged clusters, have defined structures and multiple interaction sites, resulting in their potential as building blocks for constructing POM-containing supramolecular gels. The introduction of POMs into gels not only provides strong driving forces for the formation of gels due to the characteristics of charged cluster and oxygen-rich surface, but also brings new properties sourcing from unique electronic structures of POMs. Though many POM-containing gels have been reported, a comprehensive review is still absent. Herein, the concept of POM-containing gels is discussed, following with the design strategies and driving forces. To better understand the results in the literature, detailed examples, which are classified into several categories based on the types of organic components, are presented to illustrate the gelation process and gel structures. Moreover, applications of POM-containing gels in energy chemistry, sustainable chemistry and other aspects are also reviewed, as well as the future developments of this field.

Abstract
![]()
The
reaction of mid to late lanthanide ions with the N,N′-dimethyl-N,N′-bis(2-hydroxy-3-formyl-5-bromobenzyl)ethylene-diamine organic
ligand and monolacunary Keggin type [α-SiW11O39]8– anion affords a series of isostructural
compounds, namely, K5[LnIII(α-SiW11O39)(C20H22Br2N2O4)]·14H2O (1-Ln, Ln = Sm to Lu). The molecular structure of these sandwich-type
complexes is formed by the LnIII ion in a biaugmented trigonal
prismatic geometry, which occupies the external O4 site
of the organic ligand and the vacant site of the lacunary polyoxometalate
(POM) unit. The empty N2O2 coordination site
of the organic ligand allows its unprecedented folding, which displays
a relative perpendicular arrangement of aromatic groups. Weak Br···Br
and π–π interactions established between adjacent
molecular units govern the crystal packing, which results in the formation
of assemblies containing six hybrid species assembled in a chairlike
conformation. 1-Gd and 1-Yb display slow
relaxation of the magnetization after the application of an external
magnetic field with maxima in the out-of-phase magnetic susceptibility
plots below ∼5–6 K, which is ascribed to the presence
of various relaxation mechanisms. Moreover, photoluminescent emission
is sensitized for 1-Sm and 1-Eu in the visible
region and 1-Er and 1-Yb in the NIR. In
contrast, the quenching of metal-centered luminescence in the 1-Tb derivative has been attributed to the out-of-pocket coordination
mode of the lanthanide center within the POM fragment. It is demonstrated
that the 1-Yb dual magneto-luminescent material represents
the first lanthanide-containing POM reported to date with simultaneous
slow magnetic relaxation and NIR emission. Solution stability of the
hybrid molecular species in water is also confirmed by ESI-mass spectrometry
experiments carried out for 1-Tb and 1-Tm. A series of solution stable, molecular
polyoxometalate hybrids,
namely, [α-SiW11O39LnIII(C20H22N2Br2O4)]5− (LnIII = Sm to Lu) have been synthesized
from the combination of mid-to-late lanthanides, lacunary Keggin-type
anions, and a compartmental organic ligand. Metal-centered luminescence
in both the visible and NIR region as well as slow relaxation of magnetization
was found for different members of this family, including the Yb derivative,
which represents the first POM-based system with slow magnetic relaxation
and sensitized emission in the NIR region.

Abstract
A new class of supramolecular hydrogels have been designed and synthesized via the co-assembly of basic amino acids (AAs) and heteropoly acids (HPAs) under acidic conditions. The formation of gel-like samples is identified using an inverted tube method, rheology, and scanning and transmission electron microscopy. Fourier transform infrared spectroscopy reveals that the structural integrity of the HPAs is maintained during the gelation process. X-ray photoelectron spectroscopy (XPS) and proton nuclear magnetic resonance spectroscopy demonstrate that the anionic HPAs interact with both the protonated α-NH2 and the protonated side groups of the basic amino acids, initiating the preferential growth of one-dimensional nanofibers. These nanofibers bundle and entangle with each other to form extended three-dimensional network structures. The resulting AA/HPA supramolecular hydrogels show clear stereoselectivity of the basic amino acids. With the decreasing enantiomeric excess of the basic amino acids, the gelation propensity of the AA/HPA complexes is found to be depressed. The co-assembled hydrogels show the UV-responsive photochromic behaviour because of the presence of HPAs. The corresponding XPS data confirm that the photochromism of the hydrogels is attributed to the intervalence charge-transfer transition resulting from the reduction of HPAs. Interestingly, the reduced HPAs within the hydrogel matrix can absorb the near-infrared (NIR) light and exhibit photo-thermal conversion properties, which elevates the bulk temperature of the AA/HPA hydrogels and induces the gel-to-sol transition. This study unveils that HPAs have unique capacity to promote the gelation of basic amino acids for the construction of supramolecular soft materials with functional features.
