Abstract

The invention provides a conjugated microporous polymer aggregation-induced ECL sensor based on tetraphenyl ethylene and a preparation method and application thereof. According to the invention, threekinds of TPE-CMP (namely, TPE-CMP-1, TPE-CMP-2 and TPE-CMP-3) are used for researching an ECL mechanism; the advantages of a luminescence technology and an electrochemical technology are combined; and tri(4-acetenylphenyl)amine (TEPA), 4,4'-diacetenyl biphenyl (DEBP) and 2,4,6 tri(4-acetenylphenyl)-1,3,5-triazine (TEPT) are respectively prepared by using different coupling agents, and are furtherused for constructing an ECL sensor for detecting dopamine. Testing results prove that the ECL sensor has extremely high sensitivity to dopamine and can be used for analyzing biological samples, so the ECL sensor has good practical application value.

Description

technical field [0001] The invention belongs to the technical field of electrochemiluminescence detection, and in particular relates to an electrochemiluminescence sensor induced by aggregation of tetraphenylethylene-based conjugated microporous polymers and a preparation method and application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Conjugated microporous polymer (CMP) materials based on tetraphenylethylene (TPE), a class of porous organic materials, have attracted increasing attention in the molecular design of conjugated backbones and microporous structures. High flexibility. Due to their large surface area and microporous nature, CMPs can be used as ...
