  Synthesis and spectroscopic properties of 1,3,5-tris(arylalkynyl)-2,4,6-trimethoxybenzenes

  摘要：

  A number of C-3-symetric 1,3,5-tris(arylalkynyl)-2,4,6-trimethoxybenzenes which carry electron withdrawing aryl substituents at the acetylenic periphery and donating methoxy groups on the central benzene ring are prepared via Sonogashira coupling. The utility of two different synthetic routes is evaluated as well as the effect of the nature of the aryl and ethynyl starting compounds in the coupling reaction. Finally, a correlation between the substitution pattern of the alkynyl compounds and their UV-vis and fluorescence spectroscopic properties is established. (C) 2004 Elsevier Ltd.

  one of the rare cases of single‐crystal‐to‐single‐crystal (SCSC) linear polymerizations, resulting in a novel ladder‐type polymer. The polymerization is based on the photoinduced [4+4]‐cycloaddition reactions between trifunctional anthracene‐based monomers. The careful design of the monomer anthraphane‐tri(OMe), results in perfectly stacked anthracene pairs in the crystal structure, with Schmidt's

  在这项工作中，我们介绍了单晶到单晶（SCSC）线性聚合的罕见情况之一，从而产生了一种新型的梯型聚合物。聚合基于三官能蒽基单体之间的光诱导[4 + 4]-环加成反应。精心设计的单体蒽三（OMe），可以使晶体结构中的蒽对完美堆叠，施密特距离d = 3.505–3.666Å，位移s = 1.109Å ，从而可以实现定量收率和选择性收率的选择性线性聚合。只需几分钟，而不会影响单晶的完整性。获得的聚蒽三（OMe）还揭示了一个非常有趣且前所未有的立体异构现象，这是聚蒽的特征。
