Embodiment 1

[0019] Figure 6 is the thermal stability curve of polymer 2 in Example 2. Among them, the abscissa is the temperature, and the ordinate is the maximum absorption value. The heating time for each temperature was 5 minutes. Embodiment 1,2,9,16,23-tetraaminovanadyl phthalocyanine-epoxy resin crosslinked polymer (polymer 1) and its film

[0020] Synthesis of 4-nitrophthalimide: 16.8ml of fuming nitric acid and 196ml of concentrated sulfuric acid were mixed and cooled to 12°C. Then 14.0 g of phthalimide was added thereto as quickly as possible with stirring, keeping the temperature of the mixture between 10°C and 15°C overnight. The resulting clear solution was poured into 320 g of crushed ice with vigorous stirring so that the temperature of the mixture did not exceed 20°C. Suction filter with a glass sand funnel, wash the solid matter with cold water several times, and then dry. A crude product of 12.8 g was obtained. The crude product was recrystallized with 95% ethanol t...

[0033] Synthesis of 3-nitrophthalic anhydride: Mix 13ml concentrated sulfuric acid and 10g phthalic anhydride, heat at 80°C, after the solution is clarified, slowly drop 6ml fuming nitric acid (specific gravity 1.5 l), keeping the temperature of the reactants between 100 and 110°C. After adding nitric acid, keep this temperature for 2h. The reactant was poured into 20ml of water and cooled. Add 4ml of water to the obtained solid substance, stir well, and filter with suction. The crude product was recrystallized twice with 4ml of water, and air-dried t...

Abstract

A kind of cross-linked phthalocyanine-epoxy resin polymer and its transparent uniform film is disclosed. Said film features high resistance to acid, alkali and organic solvent, high high-temp (200 deg.C) stability, and the absorbed wavelength up to 800 nm or more. It can be used for organic optical storage and non-linear optical materials.

Description

technical background [0001] Phthalocyanine is a class of compounds that are very stable to light, heat and chemical environments, and has been widely used as dyes and pigments. In recent years, their researches in electrical conduction, photoconduction, energy transfer, catalysts, nonlinear optics, and optical recording media have attracted increasing attention. [0002] Preparation of uniform and transparent thin films is a key problem encountered in many research and application fields of phthalocyanine. This is because most of the practically used phthalocyanines are hardly soluble in organic solvents. Although the crystal film can be obtained by vacuum evaporation, this method is expensive, and the obtained crystal film is prone to crystal transformation under certain conditions. The solubility of phthalocyanine is greatly improved by introducing various substituents on the phthalocyanine ring or at the central position, so that they can be doped into colorless polymers ...
