两种固体荧光有机-无机杂化物的合成、结构及强红光发射

摘要

采用(E)-4-(4-(diphenylamino)styryl)-1-methylpyridinium iodide(DPASPI,DPASP=(E)-4-(4-(diphenylamino)styryl)-1-methylpyridi-nium),设计合成2种新型有机-无机杂化物(DPASP)2[Zn(NCS)4]·2CH3OH (1)和{(DPASP)2[Cd(SCN)(NCS)3]· 2CH3OH}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.CCDC:1517533,1;1060372,2.
