Abstract

Abstract : The structures, one/two-photon optical properties and bioimaging application of two organic molecules with D–A and D–π–A models containing 6-phenyl-2, 2′-bipyridine were studied. Abstract : Two novel organic compounds with D–A (L1 ) and D–π–A (L2 ) models containing 4-( N, N -dipropylamino)phenyl [donor group (D)] and 6-phenyl-2, 2′-bipyridine [acceptor (A)] groups were synthesized and characterized by IR, 1 H NMR, 13 C NMR, MS and single crystal X-ray diffraction. Their photophysical properties were systematically investigated using both experiments and theoretic calculations. It was found that the two-photon action cross-section (δ Φ ) of the D–π–A model molecule (δ Φ L2 = 119 GM) was approximately three times larger than that of the D–A type molecule (δ Φ L1 = 43 GM). Furthermore, their cytotoxicity and applications in bioimaging were determined. The results showed thatL1 andL2 could be used as cytoplasmic dyes with high stability and low cytotoxicity.
