【摘要】 合成了两种手性配体N,N’-双（D-丙氨酸）萘四甲酰二亚胺（N,N’-bis-（D-alanine）naphthalene diimide,D-H₂AlaNDI）和N,N’-双（L-丙氨酸）萘四甲酰二亚胺（N,N’-bis-（L-alanine）naphthalene diimide,L-H₂AlaNDI）.在溶剂热条件下合成了一维链状的配位聚合物[Cd（D-AlaNDI）（4,4’-bipy）_0.5（DMF）₂]_n（1）和[Cd（L-AlaNDI）（4,4’-bipy）_0.5（DMF）₂]_n（2）.配位聚合物1为四方晶系,P4₁22空间群,一维链通过氢键和范德华力堆积成二维网状结构.配位聚合物1和2为一对对映体,两者均具有光致变色性质,其变色机理是光致电荷转移形成了AlaNDI^*自由基阴离子.更多还原

【Abstract】 Two chiral ligands,N,N’-bis-（D-alanine）naphthalene diimide （D-H₂Ala NDI） and N,N’-bis-（L-alanine）naphthalene diimide （L-H₂AlaNDI）,were synthesized.The one-dimensional chain like coordination polymers[Cd（D-Ala NDI）（4,4’-bipy）_0.5（DMF）₂]_n（1） and[Cd（L-Ala NDI）（4,4’-bipy）_0.5（DMF）₂]_n（2） were synthesized under solvothermal conditions.The crystal of coordination polymer 1 is tetragonal with space group P4₁22 and the one-dimensional chains are stacked into two-dimensional network structure through hydrogen bonds and van der Waals forces.Coordination polymers 1 and 2 are one pair of enantiomers with photochromic properties,the mechanism of which is the formation of AlaNDI^* radical anion by photo-induced charge transfer.更多还原
