Summary: The self-assembled material stabilized by halogen bonding, m-BrTBE, forms uniform ball-like aggregates with high photoluminescence quantum yield, showing a more red-shifted emission compared to TBE. The enhanced AIE behavior is attributed to the important effect of meta-bromide substituents, promoting radiative processes and blocking nonradiative relaxation pathways.

Summary: The reaction of [Au(tht)(2)](ClO4), [Cu(CH3CN)(4)](ClO4), 3,6-di-tert-butyl-1,8-diethynyl-9H-carbazole (H(3)decz), and bis(2-diphenylphosphinophenyl)ether (POP) in the presence of triethylamine (NEt3) yielded the cluster complex Au4Cu2(decz)(2)(POP)(2) as yellow crystals. The Au4Cu2 cluster exhibits a scissor-like structure sustained by two decz and two POP ligands and stabilized by Au-Cu and Au-Au interactions. The cluster shows bright yellow to orange photoluminescence and exceptional thermochromic phosphorescence characteristics.

Summary: Six mechanofluorochromic crystals have been reported, showing emission changes upon grinding in the 500-750 nm range. Replacing different moieties affects their quantum yields, with halogen substitution causing a decrease in φf. Analysis suggests that conformational changes upon grinding and reversible changes upon exposure to dichloromethane vapors are key characteristics of these crystals.

Summary: Combining AIE scaffolds with ACQ luminophores can eliminate the ACQ effect and give derived molecules new optical behavior. The manner in which the AIE scaffold connects with the ACQ luminophore determines the properties of the resulting molecules. Differences in the connection of pyrene with the ester group led to distinct fluorescence properties in molecules 1 and 2, with molecule 1 showing potential for optical recording applications.

Summary: A new strategy was developed to induce the aggregation of glutathione-capped gold nanoclusters (GSHAuNCs) by self-assembly of peptide. The resulting dual-emission probe, FF-N@GSH-AuNCs, showed one emission from the selfassembled FF-N at 470 nm and another from the aggregation-induced enhanced emission (AIEE) of GSH-AuNCs at 575 nm. The probe was used to screen and evaluate chymotrypsin inhibitors, showing significant inhibitory effects of epigallocatechin gallate (EGCG) and tannic acid on CHT activity.

Summary: The development of stimulus-responsive luminescent materials, especially those with multicolor and high-contrast chromic properties, is a critical challenge. In this study, a zinc(ii) complex was synthesized and characterized, showing aggregation-induced emission enhancement in THF/H2O mixtures and multicolor switching under external stimuli in the solid state. The complex exhibited reversible mechanochromic luminescence behavior and acidochromic properties, as well as electrochemical oxidation behavior. Based on its high-contrast and multicolor switching, the complex was successfully used in the field of rapid detection of mechanical stimuli and HCl/NH3 vapors.

Summary: Four tetraphenylethene-extended phenyl/benzoxazole compounds (TPEPBZs 1-4) were synthesized, which exhibited aggregation-induced emission behavior and multi-stimuli-responsive properties. The modification of substituents on the aggregation-induced emission luminogens (AIEgens) can change their solid structures and further mechanochromic contrasts before and after grinding. Moreover, TPEPBZs 1-4 showed significant acidichromic behavior and the emission could change reversibly between their initial color and subsequent orange emission under stimuli.
