A solid-phase polycarbazole derivative electroluminescence system and its construction method and application

Abstract

The present disclosure relates to the technical field of electroluminescence, in particular to a solid-phase polycarbazole derivative electroluminescence system, a component method and application thereof, wherein the luminescence system includes a polycarbazole derivative and a co-reactant; the polycarbazole The derivative has the following structure of formula I: in formula I, the degree of polymerization n=50-72; the alkyl group C of the polycarbazole derivative n H 2n+1 where n is 2-20, preferably 2, 4, 8, 16; the co-reactant includes tripropylamine. The electroluminescence system can not only retain the strong electroluminescence signal of the conjugated polymer, but also improve the false positive phenomenon of the traditional liquid phase electroluminescence system.

Description

technical field [0001] The present disclosure relates to the technical field of electroluminescence, in particular to a solid-phase polycarbazole derivative electroluminescence system and a construction method and application thereof. Background technique [0002] The disclosure of information 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] Electrochemiluminescence (ECL) is a phenomenon in which luminescent materials are excited by current and electric field under the action of an electric field to form excited state species on the electrode surface, and then undergo energy relaxation and rapidly return to the ground state to produce luminescence. ECL combines the ultra-sensitivity of chemiluminescence and the high controllab...

AI Technical Summary

Problems solved by technology

[0006] But so far, in the field of analytical chemistry, there are few reports on conjugated polymers used as electroluminescent reagents for sensor signal amplification.

And the polymers generally used in the electroluminescent sensing system are water-soluble, which is easy to cause false positive effects on the experimental results during the detection process.
