Abstract:
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.
