摘　　要：合成了一种新型有机染料,反式,反式-4-{4-[4-(N,N-二苯胺基)苯乙烯基]苯乙烯基}-N-甲基吡啶碘盐(简称为DPSSPI)。用X射线衍射方法测定了DPSSPI的晶体结构,其单晶属于单斜晶系,P21/c空间群,结构分析表明分子骨架具有优良的平面性。溶剂对DPSSPI的光物理性质影响很大,研究发现在氯仿中显示出强的红色荧光发射。在1 064 nm的ps脉冲激光的激发下,DPSSPI的氯仿溶液还可以发出776 nm的双光子频率上转换荧光。A new organic dye, trans, trans - 4 - / 4 - [4 - （ N, N- diphenylamino）styryl ] styryl } - N - methylpyridinium iodide （abbreviated as DPSSPI）, has been synthesized and structurally investigated. X- ray diffraction analyses reveal that the crystal belongs to monoclinic system, P21/c space group. The structure data indicate that the molecule backbone is perfectly planar. The influence of the solvent on the photophysical properties of DPSSPI is obvious and the compound inchloroform exhibits strong red fluorescene. When excited with 1 064 nm ps laser irradiation, DPSSPI in chloroform exhibits strong two - photon frequency up - converted fluorescence at 776nm.
