required for gelation was induced by the intramolecular hydrogen bond of the o-AN in the organogelator, leading to an intermolecular π-π interaction. The gelation was also facilitated by the non-covalent interaction of the van der Waals force. The gelation was investigated in terms of a molecular packing model and the organogel fluorescence. The organogel collapsed upon exposure to the fluoride anion, because
在此处键入您的摘要文本合成了一种基于邻苯基氮杂萘酚(o-AN)的有机胶凝剂,以使用所得的有机凝胶实现胶凝诱导的发射。尽管含o-AN的有机胶凝剂在溶液中不发出荧光,但其生成的有机凝胶却变成红色荧光。荧光源自o-AN的聚集诱导发射特性。凝胶化所需的结构平面化是由有机胶凝剂中o-AN的分子内氢键诱导的,从而导致分子间的π-π相互作用。范德华力的非共价相互作用也促进了凝胶化。根据分子堆积模型和有机凝胶荧光研究了凝胶化。有机凝胶在暴露于氟阴离子后会崩溃,因为o-AN的羟基被去质子化,导致氢键减弱,最后荧光消失。有机凝胶在诸如离子感测和刺激响应性相关领域的应用中具有潜在的前景。
