Abstract

Abstract : We synthesized arylene–alkynylene macrocycles containing hexayne and octayne, which enables quantitative analysis of self-association constants depending on the length of the polyyne chains for the first time. Abstract : Tetraalkoxyphenanthrylene–hexaynylene and –octaynylene macrocycles, which represent the first examples of isolable arylene–alkynylene macrocycles (AAMs) that contain polyyne chains longer than tetrayne, were synthesized and their self-association behavior was examined. Extending the polyyne chain from diyne to tetrayne, hexayne, and octayne exponentially increased the self-association constant of the macrocycles.
