摘要
通过水热法合成出一个全新的三维氢键有机框架化合物[Zn(4,4′-bipy)2(H2O)4]·(4,4′-bpds)(I)(4,4′-bipy=4,4′-联吡啶,4,4′-H2bpds=4,4′-联苯二磺酸),并对其进行了元素分析、红外、热重、荧光、粉末及单晶X-射线衍射等表征。结果表明,该化合物属于单斜晶系,P21/c空间群,a=0.92535(3)nm,b=1.21873(3)nm,c=1.44467(4)nm,β=93.450(3)°,V=1.62629(8)nm3,Z=2,R1=0.0705。化合物中相邻的[Zn(4,4′-bipy)2(H2O)4]2+配阳离子通过氢键形成一维线性链结构,进而通过三齿氢键模式的磺酸基连接成(4,4)层状结构,层间进一步由C-H…O氢键扩展为规则的三维氢键网络。此外,该化合物室温下在300~600 nm处展现出了较强的蓝光发射。
A new hydrogen-bonded organic framework,[Zn(4,4′-bipy)2(H2O)4]·(4,4′-bpds)(I),(4,4′-bipy=4,4′-bispyridine,4,4′-H2bpds=4,4′-biphenyldisulfonic acid),has been hydrothermally synthesized and characterized by elemental analysis,IR,TG,PL,powder and X-ray single crystal diffraction.Complex I crystallizes in monoclinic system with space group P21/c,a=0.92535(3)nm,b=1.21873(3)nm,c=1.44467(4)nm,β=93.450(3)°,V=1.62629(8)nm3,Z=2,R1=0.0705.Adjacent[Zn(4,4′-bipy)2(H2O)4]2+cations are joined by hydrogen bonds into 1D linear chains,which are then connected into(4,4′)layer through sulfonate groups in tridentate hydrogen-bonding mode.The C-H…O interactions further extend adjacent layer motifs into 3D hydrogen-bonding network.In addition,this complex exhibits strong blue emission at 300~600 nm in solid-state at room temperature.
