摘要/Abstract

摘要： 合成了发光配合物1,2-二(2-吡啶甲酰胺基)苯锌(1)及其双分子-4,4'-联吡啶复合物(2).用X射线单晶衍射分析方法得到了配合物2的单晶结构.该晶体属三斜晶系,P1空间群,晶胞参数为a=0.96251(6)nm,b=1.50122(9)nm,c=1.64252(12)nm,α=106.958(2)°,β=105.362(3)°,γ=102.978(2)°,V=2.0685(2)nm³,Z=2,D_c=1.563g/cm³,F(000)=1000,R₁=0.0367,wR₂=0.0898.研究表明,晶体2由1个4,4'-联吡啶通过配位键连接2个化合物1分子构成.晶体2是由沿晶体学b和c轴方向的一维分子柱堆积而成.考察了配合物1的发光性质,配合物1可作为发光材料效率很高的电致发光器件制备.

Abstract: Luminescent complexes Zn(bpb)(1) and Zn 2(bpb)₂(bpy)(2)(bpb=1,2-bis(2-pyridinecarboxamido)benzne, bpy=4,4'-bipyridine) were synthesized and complex 2 was characterized by single crystal X-ray diffraction. Crystal data for Complex 2: monoclinic, space group P1, a=0.962 51(6) nm, b=1.501 22(9) nm, c=1.642 52(12) nm, α=106.958(2)°, β=105.362(3)°, γ=102.978(2)°, V=2.068 5(2)nm³, Z=2, D_c=1.563 g/cm³, F(000)=1000, R₁=0.036 7, wR₂=0.089 8. Complex 2 was formed by two molecules of complex 1, which were linked by a bpy ligand through coordination bonds. In the solid of complex 2, there were face-to-face intermolecular π-π stacking interactions resulting in the formation of one-dimensional molecular chains, which oriented along crystallographic b and c axis, respectively. The photo and electro-luminescent properties of complex 1 were characterized. Complex 1 was employed as an emitting material to fabricate electroluminescent device with a high efficiency.
