摘要：

An electron donor-pi-bridge-electron acceptor (D-pi-A) structural optical functional organic ligand (L) comprising a triphenylamine moiety as the electron donor and pyridine moiety as the electron acceptor was synthesized. By self-assembly of L with ZnBr2 and ZnI2 in methanol and dichloromethane, two fluorescent Zinc(II) complexes ZnBr2L2 (1) and ZnI2L2 (2) were obtained. The structures of 1 and 2 were solved by single crystal X-ray diffraction analysis. Study of nonlinear optical properties has shown that the complexes exhibit excellent two photon excited fluorescence with the two-photon absorption cross-section values of 516 GM for 1 and 501 GM for 2. The structure-property relationships were detailed through X-ray crystallography. Results of living cell imaging experiments show the potential of them in fluorescence microscopy bioimaging.
