In this work, a novel supramolecular π-gel has been constructed using a naphthalimide functionalized pillar[5]arene-based gelator (MP5). The gelator MP5 simultaneously contains a naphthalimide moiety as the π⋯π interaction site as well as a fluorophore. Interestingly, the MP5-based supramolecular π-gel (MP5-G) exhibits strong aggregation-induced emission (AIE). MP5-G exhibited good thermal-responsiveness

An efficient method for the synthesis of some difunctionalized copillar[5]arene Schiff bases from condensation of salicylaldehyde and its 5-chloro, 5-bromo, 3,5-di( t -butyl) substituted derivatives with corresponding diamino-functionalized copillar[5]arene, which were prepared by Gabriel reaction according to the reported method. Single-crystals of six copillar[5]arenes were determined by X-ray diffraction
The selective detection and separation of target ions or molecules is an intriguing issue. Herein, a novel supramolecularorganicframework (SOF‐THBP) was constructed by bis‐thioacetylhydrazine functionalized pillar[5]arenes. The SOF‐THBP shows a fluorescent response for Fe3+, Cr3+, Hg2+ and Cu2+ ions. The xerogel of SOF‐THBP shows excellent recyclableseparationproperties for these metal ions and
选择性检测和分离目标离子或分子是一个有趣的问题。本文中,用双硫代乙酰肼官能化的柱[5]芳烃构建了一种新型的超分子有机骨架(SOF- T H BP)。所述SOF - Ť ħ BP示出了用于铁的荧光响应3+,铬3+,汞2+和Cu 2+离子。SOF - T H BP的干凝胶对这些金属离子显示出优异的可回收分离特性,吸收率高达99.29%。更有趣的是,通过将这些金属离子合理地引入到SOF - T H BP是由一系列金属离子配位的SOF(MSOF)组成的,例如MSOF-Fe,MSOF-Hg和MSOF-Cu。协调这些金属离子MSOFs可以选择性地感测˚F - ,溴- ,和升-Cys,分别。这些的检测限MSOFs与F - ,溴-和升-Cys为约10 -8 米。
Efficient synthesis of copillar[5]arenes and their host–guest properties with dibromoalkanes
An efficient method for the synthesis of copillar[5]arenes was developed with FeCl3 as catalyst and different 1,4-dialkoxybenzenes and paraformaldehyde as reactants (yields: 50–85%). The host–guest property of (co)pillar[5]arenes and terminal dibromoalkanes was investigated by 1H NMR measurements and an X-ray study. The complexation behavior of the copillar[5]arenes can be tuned by changing the substituents
以FeCl 3为催化剂,以不同的1,4-二烷氧基苯和低聚甲醛为反应物,开发了一种高效的Copillar [5]芳烃合成方法(收率:50-85%)。通过1 H NMR测量和X射线研究了(co)pillar [5]芳烃和末端二溴代烷烃的主客体性质。可通过改变主体上的取代基来调节Copillar [5]芳烃的络合行为。在柱[5]-和柱[6]芳烃之间发现了完全的络合选择性,这是传感器技术的一个有趣方面。
