Abstract A fluorescent supramolecular polymer network with an excellent triple-stimuli responsive property based on metal–ligand coordination and host–guest interactions has been constructed from a terpyridine-monofunctionalized leaning tower[6]arene, a tetraphenylethylene AIEgen, and a bridging coordination ion (Zn2+). Addition of competitive binding agents, trifluoroacetic acid, and/or pillar[5]arene
摘要:由三联吡啶单官能化的斜塔[6]芳烃,四苯基乙烯-AIEgen和桥联配位离子(基于金属-配体配位和主客体相互作用)构建了具有优异的三刺激响应特性的荧光超分子聚合物网络。 Zn2 +)。加入竞争性粘合剂,三氟乙酸和/或支柱[5]芳烃会破坏金属配位和/或主客体内含物的络合,并且热加热会削弱超分子聚合物凝胶中的非共价相互作用,所有这些都会导致从凝胶到溶胶的转变。
