设计并制备了一类π共轭有机合子1,3,5 -三（2-烷基硫基嘧啶基）苯（TMPB: alkyl = Me;TEPB: alkyl = Et;TPPB: alkyl = n-Pr），它们只是线性侧链的长度不同。研究发现，由于分子内的C-H⋯N氢键，这些有机合成子甚至可以与金属离子保持准平面构象。这些有机合成子与CuX2（X = Cl, Br）组装生成了四种配位聚合物：[(TPPB)CuCl2]n(1)、{[(TMPB)CuCl2]·H2O}n(2)、[(TPPB)CuBr2]n(3)、[(TEPB)CuBr2]n(4)，其中1 - 3表现为一维配位带结构，4表现为二维波状配位网络。虽然1- 3具有类似的组装层次结构，从一维带状到二维超分子层再到三维超分子结构，但可以清楚地看到调节链内或链间Cu⋯Cu距离的侧链效应；链间C-H⋯S超分子相互作用，甚至客体水分子的共存。1 - 4的室温直流（dc）导电性分别测量为9.6 × 10 - 12S cm - 1,2.9 × 10 - 9S cm - 1,2.6 × 10 - 12S cm - 1和5.7 × 10 - 11S cm - 1，其中认为2的最高电子导电性与存在独特的链间C-H⋯S相互作用有关。此外，复合阻抗技术表明，在室温下，2的交流电电导率为4.3 × 10−6S cm−1，随着温度的升高，电导率几乎呈线性下降。2的交流电导率相对于其直流电导率较高，被认为主要是由质子传导贡献的，因为事实上，在2中存在客体水分子和水分子相关的O-H⋯Cl氢键网络。2的不寻常的温度相关的交流电导率可能是由于温度敏感的O-H⋯Cl氢键网络，它负责质子传输。
A class of π-conjugated organic synthons, namely 1, 3, 5-tris(2-alkylthiolpyrimidinyl)benzene (TMPB: alkyl = Me;TEPB: alkyl = Et;TPPB: alkyl = n-Pr) was designed and prepared, which only differ in the length of linear side chain. It was found that these organic synthons can keep a quasi-planar conformation even coordinated to metal ions due to intramolecular C–H⋯N hydrogen bonds. Assembly of these organic synthons with CuX2(X = Cl, Br) generated four coordination polymers: [(TPPB)CuCl2]n(1), {[(TMPB)CuCl2]·H2O}n(2), [(TPPB)CuBr2]n(3), [(TEPB)CuBr2]n(4), among which1–3exhibit one-dimensional coordination ribbon structure and4shows a two-dimensional wave-like coordination network. Although1–3exhibit similar assembly hierarchy going from 1-D ribbon through 2-D supramolecular layer to 3-D supramolecular architecture, the side-chain-effect can be clearly seen which modulates intra-chain or inter-chain Cu⋯Cu distance; inter-chain C–H⋯S supramolecular interactions and even the co-existence of guest water molecules. The room-temperature direct-current (dc) conductivity of1–4is measured about 9.6 × 10−12S cm−1, 2.9 × 10−9S cm−1, 2.6 × 10−12S cm−1and 5.7 × 10−11S cm−1, respectively, wherein the highest electronic conduction of2is assumed to be pertinent to the existence of unique inter-chain C–H⋯S interactions. Furthermore, the complex impedance technique reveals that2exhibits a alternate-current (ac) conductivity of 4.3 × 10−6S cm−1at room temperature, which almost decreases linearly with the rising temperature. The higher ac conductivity of2against its dc conductivity is assumed to be largely contributed by proton-conduction as the matter of fact that there exist in2guest water molecules and water-molecule-associated O–H⋯Cl hydrogen bonding network. The unusual temperature-dependent ac conductivity of2is possibly due to the temperature-sensitive O–H⋯Cl hydrogen bonding network, which is responsible for proton transporting.
