High monomer concentration is a requisite for engendering the aggregation-induced emssion (AIE) phenomenon as well as the formation of supramolecular polymers. Therefore, this is supposed to ensure the generation of AIE supramolecular polymers, wherein the monomer soluability takes effect. Nevertheless, parts of supramolecular monomers are considered as poessessing different soluability towards the same sovlent, through which the polymerzation process is thus hard to proceed. Interfacial polymerzation gets over the soluabilty restriction, providing a facile method for propelling the reaction of thesemonomers. Herein, we had prepared M1 containing tetraphenylethene (TPE) functionalized with two terpyridine derivatives, then making M1 dissolving in CHCl3 to give solutions. Cu2+ solutions were fabricated through dissolving CuCl2 into H2O. Towards mixing those solutions, AIE interfacial supramolecular polymers (AIEISPs) displaying green fluorescence were generated at the interface of two phases on the basis of metal-coordination between terpyridine and Cu2+. These AIEISPs were certificated to possess the stimuli-responsiveness, for which the excessive addition of tetrabutylammonium hydroxide would cause the structure destruction owing to the stronger bonding ability with Cu2+ than that of terpyridine. These fabricated AIEISPs had provided a new avenue to prepare AIE supramolecular polymers.

AIE界面超分子聚合物
高单体浓度是产生聚集诱导发光(AIE)现象以及超分子聚合物形成的必要条件。因此,这应该确保AIE超分子聚合物的生成,其中单体溶解性起作用。然而,部分超分子单体被认为对同一溶剂具有不同的溶解度,因此聚合过程难以进行。界面聚合克服了溶解度限制,提供了一种促进这些单体反应的简便方法。在此,我们制备了含有用两种三联吡啶衍生物官能化的四苯乙烯(TPE)的M1,然后将M1溶解在CHCl 3中得到溶液。通过将CuCl 2溶解到H 2 O中制备Cu 2+溶液。在混合这些溶液时,基于三联吡啶和Cu 2 之间的金属配位,在两相界面处产生了显示绿色荧光的AIE界面超分子聚合物(AIEISP ) + . 这些AIEISP被证明具有刺激响应性,其中过量添加氢氧化四丁基铵会由于与Cu 2+ 的结合能力强于三联吡啶而导致结构破坏。这些制备的AIEISPs为制备AIE超分子聚合物提供了新的途径。
