摘　　要：为了获得具有相变的新型分子离子晶体,将乙氧基羰基甲基引入4,4'-联吡啶以降低相变势垒,在乙氧基羰甲基紫精(AeV^(2+))导向下合成得到两个新颖金属卤化物杂化材料(AeV)_(2)(Bi_(4)I_(16))(DMF)_(2)(1)和(AeV)(CoCl_(4))(2).荧光测试表明化合物1具有光致发光性质,化合物2表现出良好的光电响应性能,并结合理论计算揭示它们的结构和性能关系.In this study,we aimed to obtain novel molecular ionic crystals with phase transitions,Ethoxycarbon⁃ylmethyl was introduced into 4,4'-bipyridine to lower the phase transition barrier.Two new ethoxycarbonyl⁃methyl viologen induced metal halide-based hybrids,(AeV)_(2)(Bi_(4)I_(16))(DMF)_(2)(1),(AeV)(CoCl_(4))(2)have been syn⁃thesized and structurally determined by X-ray diffraction method,and the photoluminescence was detected on 1.Interestingly,2 exhibits good photocurrent response behavior.Electronic structure analysis was executed to correlate the structure/property.
