Novel thiocarbonyl derivatives (NIS and CRNS) with excellent ROS generation abilities are synthesized and studied as potential photosensitizers for one- and two-photon excited photodynamic therapy. In particular,NIS-MeandCRNSdisplay outstanding phototoxicity toward HeLa cells under two-photon excitation (800 nm) with negligible dark toxicity.
This study was supported by grants from the National Research Foundation of Korea (NRF) funded by the Korean government (MSIP) (No. 2012R1A3A2048814 for J. Y. and No. 2019R1A2B5B03100278 for H. M. K.).
