A facile strategy to realize single/double photon excitation- dependent photosensitizer for imaging-guided phototherapy against HeLa cancer cells at separated irradiation channels

Abstract

A novel difluoroboron fluorophore with electronic donor-acceptor conjugated structure was synthesized with 26.5% fluorescent quantum yield, 18035 GM two-photon absorbing cross-section, and undetectable two-photon fluorescence, resulting in 25% 1O2 quantum yield. The unique optical behavior of CNFBBN enabled one-photon fluorescent imaging and two-photon phototherapy against HeLa cancer cells, irradiated at separated wavelengths.
