Summary: Chemical sensors based on stimulus-responsive chromogenic materials are important for their ability to manipulate optical properties and display vivid colors. In this study, a chromogenic poly-diacetylene (PDA) was generated through polymerization of protonated supramolecular assemblies of a diacetylene precursor. The PDA exhibited a blue color and showed a sensory response to ammonia, transitioning from blue to red and emitting fluorescence upon deprotonation. The self-assembly behavior, topochemical polymerization, and ammonia sensing properties were investigated using spectroscopic methods.

Summary: A simple method for colorimetric and fluorometric profiling of AGEs was reported in this study, utilizing changes in optical properties of PTs and Apts to estimate the concentrations of AGEs in plasma, and achieving distinct profiling of different AGEs through PCA analysis. The approach allows for rapid analysis of spiked AGEs in plasma samples without the need for preanalytical processing and advanced instrumentation, facilitating on-site diagnosis.

Summary: In this study, a molecular chameleon with D-pi-A architecture, PRAA, was synthesized and utilized as a fluorescent sensor for toxic metal ions. Its selectivity towards Ag+, Hg2+, and Pb2+ ions can be adjusted by solvent polarity. The mechanism of binding and stoichiometry of interaction were established through experimental and theoretical methods. PRAA's potential as a probe for detecting Ag+ and Hg2+ ions in aqueous solutions using an anionic surfactant medium was convincingly demonstrated.

Summary: The tetra(amino)azacalix[4]arene skeleton was functionalized using various aromatic aldehydes, resulting in the formation of imidazobenzimidazole fused heterocycles. Anthracenyl and pyrenyl modified imidazobenzimidazole fused azacalix[4]arenes existed as dimers in the solid state, while the tetrapyrenyl modified product served as a Zn2+-selective sensor.

Summary: Cyanide, a highly toxic chemical mainly released from industrial production, requires selective, sensitive, and rapid monitoring techniques for detection. The efficient cyanide probe reported in this study, based on thiazolium conjugated HBT-Br derivative, shows significant color change towards cyanide under different lighting conditions. Through ESIPT and ICT processes, the probe can effectively detect cyanide at levels lower than physiologically lethal concentrations.

Summary: Two beta-formylBODIPYs show strong daylight excitable fluorescence and highly selective responses to cyanide anion. Surprisingly, cyanide anion undergoes nucleophilic addition to the alpha-position of the BODIPY core instead of the expected formyl moiety, causing interruption of pi-conjugation and significant blue-shift of absorption maxima.

Summary: Chiral transition metal complexes with privileged ligands are efficient catalysts for various asymmetric organic transformations. Transition metal complexes of C1-symmetric pyrrolidine-based ligands have been widely used in asymmetric organic reactions. However, a comprehensive review article on the transition metal complexes of chiral C1-symmetric pyrrolidine-based ligands derived from (L)-proline has not been published.
