一个具有杂金属链和蜂巢状纳米孔道结构的三维配位聚合物的合成与表征

Synthesis and Characterization of a 3D Coordination Polymer with Heterometallic Chains and Honeycombed Nanochannels

在溶剂热条件下,用预先合成的5-羟甲基间苯二甲酸(H_2HIA)与Zn2+及K+反应构建出1个具有三维开放框架结构的配位聚合物[Zn_(0.5)K_(0.5)(HIA)(H_2O)]·x Guest(1).在配合物1中,Zn^(2+),K^+与H_2HIA构建出了无限长的杂金属链和具有亲水表面的蜂巢状纳米孔道.粉末X射线衍射和热失重分析结果表明,配合物1为纯相,330℃后有机体开始分解.此外,对配合物1的荧光性质也进行了研究.

Using 5-（ hydroxymethyl） isophthalic acid（ H_2HIA） as the ligand to assemble with Zn^（2＋）ion and K~＋ ion,an open 3D coordination polymer named [Zn_（0.5）K_（0.5）（ HIA）（ H_2O） ]·x Guest（ 1） was constructed under solvothermal conditions. Complex 1 contains interesting infinite hetrometallic chains and honeycombed nanochannels. Powder X-ray diffraction（ PXRD） and thermogravimetry analyses（ TGA） techniques were applied to characterizing complex 1 and the photoluminescent properties of complex 1 were also investigated.
