Embodiment 1

[0029] Preparation of polyaniline (PANI) nano-hybrid photosensitive functional material SnTPP-PANI covalently functionalized by tin porphyrin (SnTPP):

[0030] 500mg PANI was ultrasonically dispersed in 20mL DMF for 0.5 hours, then the mixture was transferred to a 50mL round bottom flask containing 100mg SnTPP, potassium carbonate was added as a catalyst, and the reaction solution was heated and stirred in an oil bath at 120°C for 72 hours. After the reaction, the solvent was removed by distillation under reduced pressure, and the obtained solid was ultrasonically dispersed in dichloromethane and filtered with a 0.45 μm nylon membrane, and then washed with dichloromethane and deionized water until the filtrate was colorless, and the obtained dark blue solid The powder was vacuum-dried for 24 hours to obtain polyaniline nano-hybridized photosensitive functional material SnTPP-PANI (45 mg) covalently functionalized by tin porphyrin.

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.
