Synthesis and Solid-State Structure of Perfluorophenyl End-Capped Polyynes

Five new supramolecular building blocks have been synthesized on the basis of polyynes end-capped with pentafluorophenyl groups, including three symmetrical (16, 17, 18) and two unsymmetrical polyynes (7 and 12). The solid-state behavior of these molecules based on the attractive electrostatic interactions of the phenyl and perfluorophenyl groups has been examined by X-ray crystallographic analysis of 7, 12, and 16·25.

基于带有五氟苯基端基的聚炔的五种新型超分子构建模块已成功合成，其中包含三种对称型聚炔（16、17、18）和两种非对称型聚炔（7和12）。通过X射线晶体学分析对这些分子在固态下的行为进行了研究，这些行为主要归因于苯基和全氟苯基基团的静电吸引力。
