Break-in conjugated branched polymer material and preparation method and uses thereof

Abstract

The present invention relates to a conjugation-broken hyperbranched polymer material, a preparation method thereof, and a technology field of the organic photovoltaic material, and specifically to a conjugation-broken hyperbranched polymer material and a preparation method thereof. The material is used in organic active display, organic optical storage, organic photovoltaic cell, organic field effect tube, chemical and biology sensor, organic laser, etc. and the material is a polymeric material with 9, 9-diaryl fluorine as a branched monomer based on triphenylamine. The material has the advantage that synthesization is easy to be achieved, and a special non-planar structure is formed and pi-conjugate chain is broken, and the material has a high thermal stability and glass temperature. Conceivably, the series of materials will be photovoltaic functional materials with a commercialization future.

Description

technical field The invention belongs to the technical field of organic photoelectric materials. It specifically relates to an interrupted conjugated hyperbranched polymer material and a preparation method thereof, and relates to the application of these materials in organic electroluminescence, organic light storage, organic field effect tubes, organic solar cells, organic nonlinear optics, chemical and biological transmission applications in sensing and organic lasers. technical background Since 1987, the Tang Research Group of Kodak Company in the United States [Tang, C.W.; Van Slyke, S.A. Appl. Phys. Lett. Marks, R.N.; Mackay, K.; Friend, R.H.; Burn, P.L.; Since emitting Diodes) and polymer light-emitting diodes (Polymeric Light-emitting Diodes), organic flat panel display has become another generation of market-oriented display products after liquid crystal display. At the same time, other organic electronics and optoelectronic industries, including organic electrica...
