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.

Embodiment 1

[0045] A solid-phase polycarbazole derivative electroluminescent system, the specific construction method includes:

[0046] Preparation of polyethylcarbazole derivatives: first synthesize 9-ethylcarbazole, then synthesize 3,6-diformyl-9-ethylcarbazole, and then synthesize 2,5-bis-(ethoxy Phosphorylmethylene)-1,4-dimethoxybenzene (phospholipid), 3,6-diformyl-9-ethylcarbazole and 2,5-bis-(ethoxyphosphorylmethylene base)-1,4-dimethoxybenzene (phospholipid) to obtain polyethylcarbazole derivatives by Wittig-Horner reaction. The specific preparation method is as follows.

[0047] The synthesis of a, 9-ethylcarbazole

[0048] Inject 13g of KOH and 65mL of N,N-dimethylformamide (DMF) ground into powder into a three-necked flask, stir the reaction with magnetic force at 25°C for 25 minutes, add carbazole, stir and react for 40 minutes, and then dissolve ethyl bromide In an appropriate amount of DMF, slowly drop it with a constant pressure dropping funnel, drop it within 30 minutes...

Abstract

The invention relates to the technical field of electroluminescence, in particular to a solid-phase polycarbazole derivative electroluminescence system and a component method and application thereof, and the solid-phase polycarbazole derivative electroluminescence system comprises a polycarbazole derivative and a co-reactant; the polycarbazole derivative has a structure shown as a formula I, wherein in the formula I, the polymerization degree n is equal to 50-72; n in the alkyl group CnH2n + 1 of the polycarbazole derivative is 2-20, preferably 2, 4, 8 or 16; and the co-reactant comprises tripropylamine. The electroluminescent system not only can retain a strong electroluminescent signal of the conjugated polymer, but also can improve a false positive phenomenon of a traditional liquid-phase electroluminescent system.

Description

technical field [0001] The disclosure relates to the technical field of electroluminescence, in particular to a solid-phase polycarbazole derivative electroluminescence system and its construction method and application. 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] Electrochemiluminescence (ECL) is a phenomenon in which a luminescent material is excited by a current and an electric field under the action of an electric field, forms an excited state species on the surface of an electrode, and then undergoes energy relaxation to rapidly return to the ground state to produce luminescence. ECL combines the ultra-sensitivity of chemiluminescence and the high controllability...
