Abstract

The invention belongs to the field of intense laser protective materials of the military project and discloses a Sn porphyrin-polyaniline nonlinear absorption optical function material prepared by connection of covalent bonds. The nano-material has comparatively good nonlinear absorption performance. The invention mainly aims to develop the novel porphyrin covalent functionalized Sn porphyrin-polyaniline nonlinear absorption optical function material with good solubility for the problem existing in the current laser protective material and the limit of poorer solubility of a polyaniline material. In the Sn porphyrin-polyaniline nonlinear absorption optical function material, metal Sn porphyrin is covalently modified on the surface of polyaniline by the covalent bonds; the prepared organic-polymer photosensitive function material integrates the characteristics of porphyrin and polyaniline; a hybrid material has more excellent nonlinear optical property than a single material due to the synergistic effect of components, therefore, the Sn porphyrin-polyaniline nonlinear absorption optical function material has a good application prospect.
