The development of organic light-emitting devices has driven demand for new luminescent materials, particularly after the 2001 discovery aggregation-induced emission. This study focuses on fluorinated diphenylacetylene-based molecules, revealing that specific molecular modifications can enhance fluorescence and achieve a wide range photoluminescence colors. A simple effective luminescence color-tuning method is proposed to investigate behavior two-component polymer dispersion films blended with two types diphenylacetylenes, namely blue- yellow- or red-fluorescent diphenylacetylenes. It confirmed if blue green-yellow yellow fluorophores are in appropriate ratios, binary blend color coordinates (0.20, 0.32) be achieved, which approaches white point pure These findings contribute lighting display as white-light-emitting materials.

Carrier-free nanodrugs are a novel type of drug constructed by the self-assembly molecules without carrier involvement. They have characteristics small particle size, easy penetration various barriers, targeting tumors, and efficient release. In recent years, carrier-free become hot topic in tumor therapy as they solve problems low loading, poor biocompatibility, uptake efficiency nanodrugs. A series studies shown that play vital role treatment with similar or better effects than Based on literature published past decades, this paper first summarizes progress assembly modes nanodrugs, then describes common therapeutic modalities therapy, finally depicts existing challenges along future trends We hope review can guide design application future.

Abstract In this work, a near‐infrared emissive photosensitizer of 3,3‐dimethyl‐N,N‐diphenyl‐2‐(thiophen‐2‐yl)‐3H‐indol‐6‐amine functionlized benzothiazolium (DPITT) was developed. DPITT exhibited aggregation‐induced emission effect and potent type I II reactive oxygen species generation capacities after white light irradiation. Taking advantage the cationic feature, penetrated cell membrane selectively accumulated in mitochondria living cells. Upon irradiation, photosensitized able to induce mitochondrial dysfunction, leading death. Photosensitized further applied disrupt multicellular tumour spheroids, demonstrating its potential application inhibiting hypoxic solid tumours.
