金属氯化物-苯并噻唑有机-无机杂化化合物的合成、表征及荧光性质（英文）

Syntheses,Characterization and Optical Properties of Three OrganicInorganic Hybrid Compounds Based on Metal Chlorides and Benzothiazole

金属卤化物MCl2(M=Pb^(2+),Cd^(2+),Co^(2+))分别与苯并噻唑(btz)在浓盐酸中、80℃下反应,合成了3种有机-无机杂化化合物:(btzH)[(PbCl_3)](1),(btzH)_2[CdCl_4]·2H_2O(2)和(btzH)2[CoCl_4]·2H_2O(3),其中化合物2和3结构相似。对化合物1~3进行了粉末衍射、红外和紫外光谱、元素分析、热重分析以及X射线单晶衍射表征。荧光测试发现:化合物1~3在393nm处有发射峰,该荧光来源于苯并噻唑环中电子的π…π跃迁。

The reaction of three divalent metal （Ⅱ） halides MCl2（M =Pb2＋, Cd2＋, Co2＋） with two equivalents of benzothiazole（btz） in the concentrated acid HCl at 80 ℃ resulted in the formation of the corresponding organicinorganic hybrid compounds：（btz H）[（Pb Cl3）]（1）,（btz H）2[CdCl4]·2 H2O（2） and（btz H）2[CoCl4]·2 H2O（3）, in which the structures of compounds 2 and 3 are similar. All compounds have been characterized by XRD, IR, UV-Vis,EA, TG and single X-ray diffraction. Fluorescent investigation reveals that compounds 1 ~3 exhibit similar emission peaks at 393 nm, which are ascribed to the π … π transition of the btz ring.
