A nitro-functionalized Cu(ii)-based one-dimensional coordination polymer (1D CP) [Cu(nip)(4-phpy)2]n (1) (H2nip = 5-nitroisophthalic acid and 4-phpy = 4-phenylpyridine) was synthesized and characterized by elemental analysis, powder X-ray diffraction (PXRD) and single crystal X-ray diffraction (SCXRD). In the solid-state self-assembly of 1, two sets of weak intermolecular forces, CHπ interaction among the axially bound 4-phpy ligands and ππ interaction among bridging nip ligands from adjacent 1D coordination polymeric chains led to 3D supramolecular packing. Interestingly compound 1 exhibited electrical conductivity in the semiconducting regime and behaved as a Schottky barrier diode.
合成了一种基于硝基官能化铜（II）的一维配位聚合物（1D CP）[Cu(nip)(4-phpy)₂]ₙ（1）（H₂nip = 5-硝基间苯二甲酸，4-phpy = 4-苯基吡啶），并通过元素分析、粉末X射线衍射（PXRD）和单晶X射线衍射（SCXRD）对其进行了表征。在1的固态自组装过程中，两组弱分子间作用力，即轴向连接的4-phpy配体之间的CHπ相互作用以及相邻一维配位聚合物链中桥连nip配体之间的ππ相互作用，导致了三维超分子堆积。有趣的是，化合物1在半导体区域表现出导电性，并表现为肖特基势垒二极管。
