Abstract
Self-organization during the self-assembly of a series of functionalized bispyridyl organic donors with complementary di-Pt(II) acceptors into supramolecular rhomboids and rectangles is explored. The connectivity and location of functional groups on the organic donors ensures that they do not interfere sterically or electronically with their respective binding sites. Carefully controlled reaction conditions are employed so that the only means of self-organization during self-assembly is through "second-order" effects arising from the distal functional groups themselves. With the selection of functionalized systems studied, the extent of second-order self-organization varies from essentially zero to quite pronounced.
摘要
探索了一系列带有互补二价铂（II）受体的功能化联吡啶有机供体自组装成超分子菱形和矩形过程中的自组织现象。有机供体上官能团的连接性和位置确保它们在空间或电子方面不会干扰各自的结合位点。采用精心控制的反应条件，使得自组装过程中自组织的唯一方式是通过远端官能团自身产生的“二阶”效应。在所研究的功能化体系中，二阶自组织的程度从基本为零到相当显著不等。
