Dynamic supramolecular assembly: Solvent polarity plays a critical role in hydrogen‐bonding‐mediated assembly of bis(amide)‐functionalized naphthalenediimide acceptor and dialkoxynaphthalene donor chromophores. In tetrachloroethylene, a stable, charge‐transfer (CT) gel was achieved, whereas in methylcyclohexane a CT state was initially formed that gradually switched over to the more stable self‐sorted
动态超分子组装:溶剂极性在氢键介导的双(酰胺)官能化的萘二酰亚胺受体和二烷氧基萘供体生色团的氢键介导的组装中起关键作用。在四氯乙烯中,获得了稳定的电荷转移(CT)凝胶,而在甲基环己烷中,最初形成了CT状态,逐渐转变为更稳定的自分选状态(见图)。
