Tin porphyrin axially covalently functionalized multi-walled carbon nanotube nonlinear optical material and preparation method thereof

Abstract

The invention belongs to the field of war-industry high-power-laser protective materials, and particularly relates to an organic-transition-metal tin-porphyrin axial covalent functionalization multiwalled-carbon-nanotube nano-hybrided nonlinear optical function material with good nonlinear absorption performance and a preparing method thereof. According to the material and the preparing method, organic-transition-metal tin porphyrin is axially connected to the surfaces of multiwalled carbon nanotubes in a covalent bond mode through 1,3-dipole cycloaddition; due to the synergistic effect between the tin porphyrin and the multiwalled carbon nanotubes, the solubility, the dispersion stability and the nonlinear optical absorption performance of the multiwalled carbon nanotubes are improved, and the scheme is not simple physical mixing of the two different optical function materials. The prepared nonlinear optical function material has quite good solubility and quite good dispersion stability in organic polar solvents, and has quite high nonlinear optical absorption performance, and therefore the organic-inorganic nano-hybrided nonlinear optical function material shows important scientific research value and good practical application prospects.
