The invention provides a hyperbranched polyarylether sulfone copolymer containing a platinum aromatic alkyne group and a preparation method of the hyperbranched polyarylether sulfone copolymer. The preparation method comprises the following steps: carrying out nucleophilic polycondensation on a platinum aromatic alkyne branched monomer containing a fluorophenyl sulfone terminal group, aromatic organic bisphenol and 4, 4-difluorodiphenyl sulfone to obtain the soluble hyperbranched polyether sulphone copolymer containing the platinum aromatic alkyne group. According to the copolymer disclosed by the invention, due to the synergistic effect of a hyperbranched structure, a platinum aromatic alkyne chromophore, related groups in polyarylether sulfone, a related raw material ratio and a preparation method, fluorescence quenching caused by platinum aromatic alkyne molecule aggregation is improved, and excellent nonlinear optical response is shown; and in addition, the low viscosity, better solubility, thermal stabil
