Summary: A novel one-dimensional supramolecular polymer was successfully constructed from 4-(4-(1-benzyl-pyridinium)styryl)-1-methyl-pyridinium chloride guest molecule and a host CB[8], characterized by various spectroscopic techniques. Interestingly, the supramolecular polymers can transform into synergistic covalent and supramolecular polymers when irradiated with visible light, due to irreversible polymerization induced by [2+2] photodimerization controlled by cucurbit[8]uril (CB[8]).

Summary: The wavelength-dependent photo-reactivity of polyanthracene upon UV-C and VIS light irradiation was investigated. The study found that UV-C exposure increased the oxygen content on the surface of polyanthracene, leading to a decrease in surface hydrophobicity. Additionally, the photo-dimerization of polyanthracene was observed upon exposure to UV-VIS LEDs, with higher efficiency compared to the monomer anthracene.

Summary: Uniform two-dimensional platelets with tailorable shapes and controlled sizes are successfully constructed by creating new nuclei from a donor-acceptor molecule and 1-hexanol in this study. The growth of these platelets can be regulated by simply varying the amount of 1-hexanol, and complex concentric multiblock 2D heteroplatelets can be obtained by sequential and alternative addition of different donor-acceptor molecules. These platelets exhibit enhanced photostability compared to those obtained by conventional self-assembly without 1-hexanol involvement.

Summary: Efficient photodimerization of azaanthracene derivatives is challenging due to low selectivity and slow reaction rate. This study utilized cucurbit[10]uril (CB[10]), with the largest rigid and hydrophobic cavity among CB[n]s, to influence the photodimerization reaction of water-soluble 1-(2-)substituted azaanthracene derivatives. The results showed that CB[10] could promote the photodimerization of these compounds in water, leading to high efficiency and selectivity.

Summary: A supramolecular catalytic system was constructed using polycationic alpha-cyclodextrin and gold nanoparticles through a supramolecular assembly strategy. The cavity of cyclodextrin acts as the channel for substrate molecules to interact with the catalytic center. The introduction of azobenzene-modified diphenylalanine guest molecules allows for precise photo-control of catalytic activity and enables chiral recognition catalysis for chiral monosaccharides.

Summary: In this work, fluorescent gold nanoclusters were used to discriminate Candida species nondestructively through the interaction between the surface ligands of gold nanoclusters and the cell walls of the species. The variation of cell wall composition leads to different degrees of association with the gold nanoclusters, enabling the identification of Candida species through fluorescence enhancement.
