Here we report the facile synthesis of two triphenylethylene-modified pyrrolopyrrole aza-BODIPY dyes with an aggregation-enhanced emission feature. NIR-emitting nanoparticles with remarkable photostability properties and applications in bioimaging were generated due to their good dispersity in water and biocompatibility.

CsPbBr (CPB) perovskite has demonstrated unique advantages as a photoelectric material. However, its stability and optoelectronic properties exhibit significantly susceptibility to environmental conditions during practical applications. Additionally, the synthesis of CPB often involves complex procedures and stringent requirements for the experimental environment, resulting in low yield.

Monodisperse gold nanoclusters constitute a new branch of nanomaterials with atomically precise molecular structures. Recently, we developed a "cluster-from-cluster" approach to assemble gold nanoclusters [Au(SR)] (Au25) atomically precise Au13 precursors. Herein we demonstrated that efficient synthesis of Au(SR) (Au36) nanoclusters can be realized this facile approach.

Through the PFOEP-SO3(-) + multidrug molecules constructed nanoparticle (NP) experiments and validated by molecular simulation docking experiments, we propose a molecular interaction principle for inducing aggregation-induced locally excited emission (AILE) luminescence from fluorenone (FO)-based conjugated polymers (CPs). Based on this molecular interaction mechanism, we constructed a NP built by π-π stacking. The NPs demonstrate facile synthesis, robust stability, and high drug-loading efficiency, enabling tumor-specific drug release in acidic lysosomal environments (pH 3.

The carbodiimide anions which were generated in situ from -cyano--aryl--toluenesulfonamides (NCTS) in the presence of the base participated in annulations that remain less reported to date. Herein, we have developed for the first time an efficient and environmentally friendly [4 + 2] annulation reaction of CF-substituted hetero-1,3-dienes with NCTS for the efficient synthesis of CF-substituted 4-1,3-oxazines and 2-aminopyrimidines under transition-metal-free conditions. The methodology demonstrates the advantages of readily available substrates, simple operation, good functional group tolerance, and broad substrate scope, providing a promising route to the synthesis of structurally diverse CF-substituted scaffolds.

This article presents a reproducible and affordable methodology for fabricating organic nanowires (ONWs) and nanotrees (ONTs) as light-enhanced conductometric O sensors. This protocol is based on a solventless procedure for the formation of high-density arrays of nanowires and nanotrees on interdigitated electrodes. The synthesis combines physical vapour deposition for the self-assembled growth of free-phthalocyanine nanowires and soft plasma etching to prompt the nucleation sites on the as-grown ONWs to allow for the formation of nanotrees.
