Summary: A new strategy for NO detection based on aggregation-induced electrochemical luminescence (AIECL) and halogen bonding effect was developed in this study. [Ru(phen)(2)(phen-Br-2)](2+) exhibited enhanced AIECL properties compared to its AIE intensity in a water-acetonitrile system. A detection limit of 2 nM was achieved with a linear range of 5 orders of magnitude. The combination of AIECL system and halogen bond effect expands the applications in biomolecular detection and medical diagnosis stages.

Summary: A series of TPE derivatives functionalized with perfluoroaryl iodo-triazole halogen bond donors have been reported for anion recognition. These derivatives form luminescent nanoscale aggregates driven by anion coordination, serving as a powerful sensory mechanism for parts per billion concentration chloride sensing. The geometric isomers of these derivatives also act as unprecedented photoswitchable XB donor anion receptors, with the photostationary state composition modulated by the presence of a coordinating halide anion.

Summary: This paper systematically investigated the aggregation-induced electrochemiluminescence (AIECL) of a ruthenium(II) complex in solvents with different water/acetonitrile volume ratios. It was found that the aggregation-induced electrochemiluminescence properties were enhanced with an increase in the proportion of water in the solvent mixture. Transmission electron microscopy and dynamic light scattering confirmed the aggregation of the complex molecules into nanoclusters. Using this aggregation-induced luminescence performance, the quantitative detection of dopamine was achieved with a good linear range and detection limit.

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: A novel aggregation-induced emission (AIE) material, maltose (mal), was discovered in this study. The presence of various oxygen clusters with rigid conformations in mal makes the clustering-triggered emission (CTE) mechanism more rational. Mal can serve as a biosensor for detecting Fe3+ since its fluorescence can be quenched by Fe3+. Additionally, mal exhibits room temperature phosphorescence, making it highly promising for anti-counterfeiting display and three-color bioimaging.

Summary: Organic luminescent materials, especially π-conjugated systems, are crucial for modern optoelectronic devices. In this study, we synthesized six hydrazone derivatives using a one-step condensation reaction. The introduction of a conjugated π-system resulted in significant red-shifts in absorption spectra. These hydrazones exhibited weak fluorescence in dilute solution but significantly enhanced emission in aggregated states with nanoaggregate formation confirmed by DLS and SEM studies. In their crystalline state, all compounds showed red to NIR emissions with high quantum efficiency up to 75%.
