Abstract

Bimolecular coupling/unimolecular cyclization strategies, including McMurry- and Glaser-type homocoupling reactions, were utilized to synthesize two shape-persistent elliptic macrocycles, which consist of polycyclic aromatic hydrocarbon units. The identity and purity of both macrocycles MC1 and MC2 were verified by 1H and 13C NMR, elemental analysis, as well as MALDI-TOF MS. The photophysical properties of MC1 and MC2 in dilute solution were also investigated.

摘要

双分子偶联/单分子环化策略，包括麦克默里（McMurry）型和格拉泽（Glaser）型均偶联反应，被用于合成两个由多环芳烃单元组成的具有形状持久性的椭圆形大环化合物。大环化合物MC1和MC2的结构和纯度通过1H和13C核磁共振、元素分析以及基质辅助激光解吸电离飞行时间质谱（MALDI-TOF MS）得以验证。同时还研究了MC1和MC2在稀溶液中的光物理性质。
