Abstract

The invention provides a supermolecular polymer photoelectric material and application thereof to a photoelectric device. The supermolecular polymer photoelectric material comprises an A1 unit, an A2 unit, a functional group B and a functional group C, wherein the functional group B and the functional group C are connected with the A1 unit and the A2 unit respectively; the A1 unit and the A2 unit are oligomers containing conjugation units or small molecular components containing conjugation units; the functional group B is crown ether; the functional group C is a secondary ammonium salt; the functional groups B and C are connected with each other through a hydrogen bond; and the crown ether and a secondary ammonium salt material have very strong coaction in reagents such as chloroform / acetonitrile, toluene / acetonitrile, chlorobenzene, o-dichlorohenzene and the like, so that a supermolecular polymer can be formed. The supermolecular polymer has the characteristics of determination of a small molecular structure, easy purification, multiple functions, solution processability and the like. The defects of the need of vapor deposition processing, unstable polymer structure, difficulty in purifying and the like existing in the conventional small molecular photoelectric material are overcome. The supermolecular polymer photoelectric material can be applied to an organic photoelectric device as a novel supermolecular polymer photoelectric material.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a supramolecular polymer photoelectric material formed by the interaction of a crown ether and a secondary ammonium salt and its application in organic photoelectric devices. Background technique [0002] Due to its high brightness, light weight, low operating voltage, thin device thickness, and wet processing methods such as spin coating or inkjet printing, organic light emitting diodes have a wide range of applications in the fields of flat panel display and organic lighting. Application prospects. Since 1987, Deng Qingyun Research Group [Tang, C.W.; Van Slyke S.A.et.al; Appl. Phys. Lett. 1987, 51, 913.] of Kodak Company of the United States invented the organic small molecule thin film electroluminescent device with a sandwich device structure, In 1990, the R.H.Friend research group of the University of Cambridge [Burroughes, J.H.; Bradley, D.D.C., Fri...
