  Self-assembly of enantiopure and racemic 2,2′,6,6′-tetrasubstituted biaryl tectons into hydrogen bonded chiral squares and infinite chiral square layers

  摘要：

  Both chiral and achiral hydrogen bonding o-,o-,o'-,o'-tetrasubstituted biaryls often exhibit unique self-assembling properties giving rise to chiral square cyclotetramers. The individual chiral squares self-assemble further with the formation of infinite layers which are either achiral or are chiral (homochiral). A priori analysis reveals various hydrogen bonding modes which may take part in the self-assembly, differing each from the other by structure and symmetry of the resulting squares and layers. Results of the theoretical analysis are compared with the experimental findings obtained from X-ray crystallographic analysis of three novel and two already known isosteric biaryl tectons, (S)-2a, (RS)-2a, 3a, (S)-5 and (RS)-5, respectively.

  4,4'-二硝基-2,2'，6,6'-四羧基联苯与N-杂环的共晶体和盐：Criss-Cross对准的烯烃的固态光二聚化和光物理性质

  摘要：

  已显示化合物4,4'-二硝基-2,2'，6,6'-四羧基联苯（H 4 A）与各种N杂环（例如4,4'-联吡啶乙烯，4,4'）共晶和形成盐-联吡啶，4,4'-联吡啶乙烷，1,10-菲咯啉，吩嗪和2-（2-（吡啶-4-基）乙烯基）-1 H-咪唑并[4,5- c ]吡啶在MeOH溶剂中。分析了所有配合物的晶体结构，包括酸碱体系中的质子化-去质子化，氢键合成子和堆积相互作用。分子H 4 A取决于甲醇溶液的浓度，与共形成剂4,4'-联吡啶基乙烯形成共晶以及盐。在其他共形成剂中，仅发现吩嗪形成共晶体。从配合物的结构分析中得出的各种氢键构架包括一维链，二维人字形和矩形网格网络以及三维伪菱形网络。尽管从烯烃双键的纵横交错排列，发现从共形成剂4,4'-联吡啶基乙烯获得的共晶体具有光反应性以进行固态光二聚反应。通过漫反射光谱和固态光致发光研究探索了所有配合物的光物理性质。

  日期：1998.4

  Four new activated core molecules suitable for use in solution-phase combinatorial organic chemistry have been prepared. These molecules represent an attempt to further explore shape-space and increase the structural diversity of prepared libraries, as well as to incorporate recognition elements in the cores to increase the chances for interaction with biological targets. Demonstrations of deconvolution strategies used to simplify complex libraries and build individual molecular species based on the cores are also provided. (C) 1998 Published by Elsevier Science Ltd.
