Optical properties, bioimaging and theoretical calculation of a Zn(II) complex based on triphenylamine derivative

A new fluorescent material was prepared by complexation of a D-π-A structural organic ligand with ZnBr2. The material exhibits good one- and two-photon excited fluorescence. One- and two-photon fluorescence imaging shows that HepG2 cytoplasm can be labeled by the fluorescent material. The results show that the material has great potential in fluorescence microscope imaging.
