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.
