ABSTRACT Phototheranostics with near‐infrared fluorescence and reactive oxygen species generation ability high photothermal conversion efficiency (PCE) plays a significant role in imaging‐guided synergetic photodynamic therapy of tumors. Here, star molecule organic photovoltaic materials, NCBDT‐4C an A‐D‐A conjugated structure, was assembled DSPE‐PEG‐NH 2 to prepare water dispersive nanoparticles (NPs). The prepared NCBDT‐4Cl NPs exhibited maximum NIR absorption peak at 764 nm 798 nm. These could generate superoxide anion, singlet ( 1 O ), heat under 808 laser irradiation. quantum yield PCE the were 37.5% 53.6%, respectively. combination cancer demonstrated vitro vivo. This work presents advanced application materials phototherapy.

Aggregation-induced emission (AIE) photosensitizers are promising for photodynamic therapy, yet their short excitation wavelengths present a limitation. In this study, we develop series of organic with dual modulation capabilities based on excited-state intramolecular proton transfer (ESIPT) and AIE. Notably, synthesize near-infrared (NIR)-excited photosensitive nanoparticles through coassembly strategy utilizing upconversion (UCNPs) amphiphilic polymers. The spectroscopic analysis theoretical calculations elucidate the significant impact additional or π-spacer groups conformational change energy barrier ESIPT process. An efficient Förster resonance between photosensitizer UCNPs is achieved strategy. Both
