Abstract
High monomer concentration is a requisite for engendering the aggregation-induced emssion(AIE)phe-nomenon 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.Neverthe-less,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 polymerza-tion gets over the soluabilty restriction,providing a facile method for propelling the reaction of the-semonomers.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 fabri-cated 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.
