[0050] (1) Para-chloromethylation of benzene ring

[0051] Dissolve polystyrene elastomer in chloroform solvent, use 1,4-dichloromethoxybutane as chloromethylation reagent, under the catalysis of tin tetrachloride, ice-water bath for several hours, react to obtain chloromethylation Based polystyrene elastomer. The chloromethyl grafting ratio increases with the prolongation of the reaction time, and different chloromethyl grafting ratios can be obtained by controlling different reaction times.

[0052] (2) para-formylation of benzene ring

[0053] Dissolve the chloromethylated polystyrene elastomer in xylene solvent, use DMSO as a mild oxidant, add potassium iodide and sodium bicarbonate, and react at 110°C for 6 hours to obtain the aldylated polystyrene elastomer. The added amount of the formylation reagent is all in excess of the theoretically calculated value to ensure that all chlorometh...

Abstract

The invention discloses a metal porphyrin polystyrene elastomer and a preparation method and application thereof. A metal porphyrin polystyrene elastic composite material is an organic photoelectric conversion material and prepared by chloromethylation, aldehydes, porphyrin and metallization in sequence. The porphyrin graft rate can only be within 5%-55% of the specific range of the metal porphyrin polystyrene elastomer, the porphyrin polystyrene elastomer can have better photoelectric responsiveness while elasticity and flexibility of the porphyrin polystyrene elastomer are maintained, and particularly, according to the metal porphyrin polystyrene elastomer and the preparation method and application thereof, through the metallization of the porphyrin polystyrene elastomer and complexationof metal ions in the middle of porphyrin rings, the photoelectric responsiveness of the porphyrin polystyrene elastomer is further improved.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric conversion materials, and in particular relates to a metal porphyrinated polystyrene elastomer and its preparation method and application. Background technique [0002] The sun is a huge energy pool, and the solar energy received by the earth in a year is as high as 1.8×10 18 kWh. The purpose of research and development of photoelectric conversion materials is to utilize solar energy. The requirements of solar cells for photoelectric conversion materials are high conversion efficiency and large-area devices to better absorb sunlight. [0003] The photoelectric conversion materials that have been used are mainly monocrystalline silicon, polycrystalline silicon and amorphous silicon. Devices made of these inorganic silicon-based photoelectric conversion materials are often hard profiles, lack of elasticity and flexibility, and cannot be folded and stretched repeatedly. , squeezed, c...
