Abstract The supramolecular assembly with quadruple fluorescence switching behavior was fabricated by the complexation of cationic ferrocenyl surfactant, 16-alkyl (ferrocenyl-methyl) ammonium bromide (Fc16AB) and anionic dye molecule, Orange G (OG) via ionic self-assembly (ISA) strategy. The obtained micromaterials exhibited different morphologies (including rod-like fiber, spindle micelle and fiber bundle) and significant switchable fluorescence behavior triggered by the addition of Ce(SO4)2 and the formation of β-CD inclusion, which corresponded to “off” and “on” state of fluorescence behavior respectively. The mechanisms of fluorescence quenching and aggregation-induced emission enhancement caused by each modulation were discussed in detail. The assembly with quadruple switchable fluorescence will be meaningful in the application of multifunctional photoelectric devices.

离子自组装策略制备具有四重可切换荧光的超分子组装体

摘要 通过阳离子二茂铁基表面活性剂、16-烷基（二茂铁基甲基）溴化铵（Fc16AB）和阴离子染料分子橙色G（OG）通过离子自组装（ISA）络合制备了具有四重荧光开关行为的超分子组装体。战略。获得的微材料表现出不同的形态（包括棒状纤维、纺锤体胶束和纤维束）和显着的可切换荧光行为，由 Ce(SO4)2 的添加和 β-CD 夹杂物的形成触发，对应于“关闭”和荧光行为的“开启”状态。详细讨论了每种调制引起的荧光猝灭和聚集诱导发射增强的机制。
