The structure of the compound was solved by single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group P21, with a = 9.753(5), b = 8.815(5), c = 25.554(5) ?, β = 96.315(5)°, V = 2184(2) ?~3, Z = 2, D_c = 1.136 g/m^3, F(000) = 792, Μr = 746.92, μ = 0.069 mm^(-1), the final R = 0.0658 and wR = 0.1730 for 6790 observed reflections with I > 2(I). Study of nonlinear optical properties shows that the compound exhibits excellent two-photon excited fluorescence with the two-photon absorption cross-section value of 116 GM. The structure-property relationship was researched in detail through X-ray crystallography and quantum chemical calculation. Result of living cell imaging experiment shows its potential in fluorescence microscopy bioimaging.展开更多

By coordination of the ligand with CdI2, a complex CdI2 L2 was obtained. The structure of the complex was analyzed through single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 25.277(5), b = 11.176(5), c = 17.912(5) ?, β = 106.056(5)°, V = 4863(3) ?3, Z = 4, Dc =1.633 Mg/m3, F(000) = 2360, Μr = 1195.19, μ = 1.766 mm-1, the final R = 0.0323 and wR = 0.0758 for 33414 observed reflections with I > 2?(I). The linear absorption spectra of the complex were experimentally and theoretically studied. And the third-order nonlinear optical(NLO) property of the complex was also measured through Z-scan technique.展开更多

The crystal structure was determined through single-crystal X-ray diffraction analysis. It crystallizes in monoclinic, space group P2_(1) with a = 9.6610(5), b = 8.9093(4), c = 26.303(1)Å, β = 96.262(4)°, V = 2250.5(2)Å^(3), Z = 4, D_(c)= 1.220 Mg/m^(3), F(000) = 872, Μr = 413.50, μ = 0.072 mm^(-1), the final R = 0.0569 and wR = 0.1700 for 8976 observed reflections with I > 2σ(I). Optical properties were studied in detail through theoretical calculation and experimental study. The result reveals that the compound exhibits excellent fluorescence performance and it can be compatible in the cytoplasm of NIH/3T3 cells, showing potential in fluorescence microscopy bioimaging.展开更多
