合成了两种π共轭有机结构单元TMPB和TPPB（TMPB = 1，3，5-三（2-甲硫基-嘧啶-4-基）苯; TPPB = 1，3，5-三（2-丙硫基-嘧啶-4-基）苯），它们的区别仅在于与硫相连的直链侧链长度不同。TMPB和TPPB配合物的结构比较表明，侧链在调节分子结构和分子排列方面具有很大的作用。TMPB和TPPB与CuI在相同条件下的反应表明，侧链对配位聚合物的组装有影响。与CuI的组装反应对侧链长度的变化敏感，即侧链越短，反应越快。TPPB与CuI反应生成[Cu 4 I4（TPPB）2]n（1）的一维链状结构，该结构由两个不同的Cu 4 I4团簇组成，而TMPB只能得到微晶粉末或沉淀物。因此，侧链可以在组装结构以及组装方式方面调节配位聚合物的组装。有机结构单元的侧链对配位聚合物的组装结构和排列方式具有调节作用。
Two π-conjugated organic building blocks, TMPB and TPPB (TMPB = 1,3,5-tris(2-methylthiol-pyrimidin-4-yl)benzene; TPPB = 1,3,5-tris(2-propylthiol-pyrimidin-4-yl)benzene), have been prepared which only differ in the length of linear side chain attached to sulfur. Structural comparison between complexes of TMPB and TPPB reveals that the side chain has a great effect in modulating both the molecular structure and the molecular alignment. Reactions of TMPB and TPPB with CuI under the same conditions show that the side chain can exert impact on the assembly of coordination polymer. Assembly reaction with CuI is sensitive to the change in length of side chain, that is the shorter the side chain, the faster the reaction. Reaction of TPPB with CuI gives a 1-D chain structure of [Cu4I4(TPPB)2]n (1) based on two distinctive Cu4I4 clusters, whilst only microcrystalline powder or precipitate can be obtained for TMPB. The side chain can, thus, tune the assembly of coordination polymer in terms of the assembly structure as well as its packing manner. The side chain of organic building blocks can modulate the assembly of coordination polymer with respect to the assembly structure and packing alignment.
