Abstract

The invention provides a tetraphenylethylene-based conjugated microporous polymer aggregation-induced electrochemiluminescence sensor, a preparation method and application thereof. The present invention uses three kinds of TPE-CMP (namely TPE-CMP-1, TPE-CMP-2 and TPE-CMP-3) to study the ECL mechanism combining the advantages of luminescence and electrochemical technology, by using different coupling agents respectively Tris(4‑ethynylphenyl)amine (TEPA), 4,4'‑diethynylbiphenyl (DEBP) and 2,4,6 tris(4‑ethynylphenyl)‑1,3,5 ‑triazine (TEPT), and was further used to construct an ECL sensor for the detection of dopamine. It has been verified by experiments that the electrochemiluminescent sensor has extremely high sensitivity to dopamine and can be used in the analysis of biological samples, so it 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 based on tetraphenylene conjugated microporous polymer aggregation-induced aggregation, and a preparation method and application thereof. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] Conjugated microporous polymer (CMP) materials based on tetraphenylethylene (TPE) have attracted increasing attention, CMP is a class of porous organic materials and has great potential in the molecular design of conjugated frameworks and microporous structures High flexibility. Due to its large surface area and micropo...
