摘　　要：合成了两个新的有机晶体:反式-4-[4＇-(N-羟乙基-N-甲基胺基)苯乙烯基]-N-甲基吡啶对甲苯磺酸盐trans-4-[4＇-(N-hydroxythyl-N-methylamino)styryl]-N-methylpyridinium toluene-p-sulfonate(简称HMASPS)和反式-4-[4＇-(N-羟乙基-N-乙基胺基)苯乙烯基]-N-甲基吡啶对甲苯磺酸盐trans-4-[4＇-(N-hydroxyethyl-N-ethylamino)styryl]-N-methylpyridinium toouene-P-sulfonate(简称HEASPS).用X射线衍射方法对这两个单晶进行了结构测定.测试了它们频率上转换荧光及激光性质.在1064nm的ps脉冲激光的激发下,HMASPS和HEASPS在溶液中均发出～625nm的上转换荧光和激光,并且有可观的激光效率.Two new organic salts, trans - 4 - [4' - (N - hydroxyethyl - N - methylamino)styryl] - N -methylpyridinium toluene - p- sulfonate (abbreviated as HMASPS) and trans - 4 - [4' - (N - hydroxyethyl - N - ethyl - amino) styryl] - N - methylpyridinium toluene - p - sulfonate (abbreviated as HEASPS) have been synthesized. Their structures were determined by X - ray diffraction method. Upon irradiation with a picosecond pulse laser at 1064nm, the solutions of HMASPS and HEASPS emitted up - conversion fluorescence at - 640nm and lased at - 620nm.
