摘　　要：通过氯化锰和2-二甲氨基异丙基氯盐酸盐在溶液中的反应,制备了一类绿光分子基晶态材料:(C_5H_(13)ClN)_2[MnCl_4](1)。该材料在紫外光激发后发出强烈的绿色荧光,并且热分析测试表明其具有较好的热稳定性(分解温度大于450 K)。结构和光谱分析表明其优异的光学性能归因于[Mn X4]2-四面体中Mn^(2+)的~4T_1(G)→~6A_1电子跃迁。Reaction of MnCl2 and 2-dimethylaminoisopropyl chloride hydrochloride afforded one novel molecular-based material, （C5H13ClN）2[MnCl4] （1）. And it is interesting to note that 1 exhibits intense greenish fluorescent emission （520 nm） at room temperature and relatively high thermal stability（stable up to 450 K）. Moreover, structure and spectra analyses reveal that its excellent optical property can be attributed to the 4T1（G）→6A1 electronic transition of Mn2＋ in[MnX4]2- tetrahedron.
