Herein, a series of photosensitizers were constructed of α, β and γ-isomers of terpyridine and the corresponding N-methylation derivatives. Benefiting from the tunable singlet-triplet energy gap and aggregation-induced emission characteristics, two-photon active photosensitizers L2b and L2c showed relatively strong intersystem crossing facilitating 1O2 generation and cell apoptosis with near-infrared excitation.
在此，构建了一系列由三吡啶的α、β 和 γ-异构体及其相应的 N-甲基化衍生物组成的光敏剂。得益于可调的单重态-三重态能量隙和聚集诱导发射特性，双光子活性光敏剂 L2b 和 L2c 显示出相对较强的系间窜越，有利于在近红外激发下产生 1O2 和细胞凋亡。
