采用水热法合成了三种Ni（II）配位超分子聚合物[Ni（pdc）（H2O）（3）]（n）（1），{[Ni（Imh）（4）（H2O）（2）] [Ni（btec）（H2O）（2）（lmh）（2）]中心点H2O}（n）（2），[Ni（opha）（phen）（H2O）（3）]中心点H2O（3）（H（2）pdc =吡啶-2，3-二甲酸，H（4）btec = 1，2，4，5-苯四甲酸，opha =邻苯二甲酸，phen = 1，10-菲咯啉，Imh =咪唑）。配合物（1）和（2）具有一维无限配位链结构，配位链通过氢键分别连接成二维和三维结构。配合物（3）是通过氢键连接的一维配位超分子化合物。配合物（1）~（3）的表面光电压谱（SPS）结果表明，配合物在300-800 nm范围内均表现出正的表面光电压响应，具有p型半导体特性。(C)2006 Elsevier B.

Three Ni(II) coordination supramolecular polymer [Ni(pdc)(H2O)(3)](n)(1), {[Ni(Imh)(4)(H2O)(2)] [Ni(btec)(H2O)(2) (lmh)(2)]center dot H2O}(n)(2), [Ni(opha)(phen)(H2O)(3)]center dot H2O (3) were synthesized by hydrothermal method (H(2)pdc = pyridine-2,3-dicarboxylic acid, H(4)btec = 1,2,4,5-benzenetetracarboxylic acid, opha = o-phthalic acid, phen = 1, 1 0-phenanthroline, Imh = Imidazole). Complexes (1) and (2) possess ID infinite coordination chain structure and the chains are separately further connected to 2D and 3D structure by hydrogen bonds. Complex (3) is a 1D coordination supramolecular compound via the connection of hydrogen bonds. The results of surface photovoltage spectrum (SPS) for complexes (1)-(3) indicate that three complexes exhibit positive surface photovoltage (SPV) response in the range of 300-800 nm, and possess the characteristic of p-type semiconductor.
