摘要

Abstract: Two acyclic and three macrocyclic polyethers, three [2] catenanes, and one [2] rotaxane, each containing one 4, 4'-azobiphenoxy unit, have been synthesized. In solution, the azobenzene-based acyclic polyethers are bound by cyclobis (paraquat-p-phenylene) Ða tetracationic cyclophaneÐin their trans forms only. On irradiation (l ˆ 360 nm) of an equimolar solution of the tetracationic cyclophane host and one of the guests containing a trans-4, 4'- ...
