A novel coordination compound, {[Cd(BDC)(Bpybc)(1.5)].10H(2)O}(n), obtained by the reaction of CdCl(2) with 1,1'-bis(4-carboxybenzyl)-4,4'-bipyridinium dichloride (H(2)BpybcCl(2)) and 1,4-benzenedicarboxylic acid (H(2)BDC), contains 1D polymeric chains that are comprised of alternating rings and rods and dangling lateral arms. These 1D polymeric motifs are interlaced via rotaxane-like mechanical linkages to give 2D armed-polyrotaxane sheets, which are further mutually polythreaded via pseudorotaxane-like mechanical linkages to form a 3D polypseudorotaxane array. Notably, a sandwich-type donor-acceptor-donor stacking is formed within each ring as a consequence of both types of polythreading in this species, and photoinduced and thermal-induced reduction of bipyridinium occurs with a color change from light yellow to blue.
一种新颖的配位化合物，{[Cd(BDC)(Bpybc)(1.5)].10H(2)O}(n)，是由 CdCl(2)与 1,1'-双(4-羧基苄基)-4,4'-联吡啶二氯化物（H(2)BpybcCl(2)）和 1,4-苯二甲酸（H(2)BDC）反应得到的，包含由交替的环和棒以及悬垂的侧臂组成的 1D 聚合链。这些 1D 聚合基序通过类轮烷的机械连接交织在一起，形成 2D 带臂聚轮烷片，这些片通过类假轮烷的机械连接进一步相互穿线，形成 3D 聚假轮烷阵列。值得注意的是，由于该物种中两种类型的穿线，每个环内都形成了一种三明治型给体-受体-给体堆积，并且伴随着颜色从浅黄色变为蓝色，发生了双吡啶的光诱导和热诱导还原。
