摘　　要：采用(E)-4-(4-(diphenylamino)styryl)-1-methylpyridinium iodide(DPASPI,DPASP=(E)-4-(4-(diphenylamino)styryl)-1-methylpyridinium),设计合成2种新型有机-无机杂化物(DPASP)_2[Zn(NCS)_4]·2CH_3OH(1)和{(DPASP)_2[Cd(SCN)(NCS)_3]·2CH_3OH}n(2)。通过单晶X射线衍射进行了表征,结果表明杂化物1和2是由有机吡啶阳离子和异硫氰酸金属配阴离子组成的,具有不同空间结构。通过1H NMR谱图解释了离子间相互作用。对具有高量子产率的杂化物1和2的红光发光性质进行了研究。Two organic-inorganic hybrids, （DPASP）2[Zn（NCS）4]·2CH3OH （1） and {（DPASP）2[Cd（SCN）（NCS）3]·2CH3OH}n （2）, have been facilely prepared from （E）-4-（4-（diphenylamino）styryl）-1-methylpyridinium iodide（DPASPI, DPASP=（E）-4-（4-（diphenylamino）styryl）-1-methylpyridinium） at gram scale. Their crystal structures have been confirmed by single-crystal X-ray diffraction analysis, which show that the hybrids 1 and 2 consist of organic pyridium cations and metal thiocyanato anions bearing different spacial structure through self-assembly processes. Furthermore, the interactions between the ions have been investigated by 1H NMR spectra. Finally, red photolumencent properties with enhanced quantum yields of hybrids 1 and 2 were investigated.
