o-Phenylene tetramers have been coassembled with linkers into macrocycles through imine condensation. Variation of linker connectivity and length allows both [1 + 1] and [2 + 2] macrocycles to be obtained, complementing (previously reported) [3 + 3] macrocycles. For the [1 + 1] macrocycles, linker length has a clear effect on o-phenylene geometry and macrocycle stability. For the [2 + 2] macrocycles, both homo- and heterochiral configurations are observed, suggesting limited communication of helix handedness in these systems.

扭曲的邻苯撑大环的连接子指导的组装

邻苯二甲四聚体已通过亚胺缩合与接头共组装成大环。链接器连接性和长度的变化允许同时获得[1 + 1]和[2 + 2]宏周期，从而补充（先前报道的）[3 + 3]宏周期。对于[1 +1]大环，连接基的长度对邻亚苯基的几何形状和大环稳定性具有明显的影响。对于[2 + 2]大环，同时观察到了同手性和杂手性构型，这表明在这些系统中螺旋惯性的交流有限。
