Embodiment 1

[0023] Add 1 mg of titanyl phthalocyanine to 20ml of benzenesulfonic acid, heat and stir for 10 minutes, put the clean aluminum sheet into the phthalocyanine solution, and use the electric field and magnetic field together for 20 minutes. Take out the aluminum sheet in a vacuum oven at 100°C (vacuum Bake at -700mmHg) for one hour and take it out to obtain a phthalocyanine film.

Embodiment 2

[0025] Add 5 mg of titanyl phthalocyanine to 30ml of mixed solvent of benzenesulfonic acid and toluene (volume ratio is 10:1), heat and stir for 30 minutes, put the clean ITO glass into the phthalocyanine solution, apply an electrostatic field for 1 minute, and take it out The ITO glass was baked in a vacuum oven (vacuum degree of -700 mmHg) at 100°C for one hour and taken out to obtain a phthalocyanine film.

Embodiment 3

[0027] Add 1 mg of bisphthalocyanine erbium to 20ml N,N'-dimethylacetamide, heat and stir for 10 minutes, put the clean aluminum sheet into the phthalocyanine solution, perform electrophoresis for 20 minutes, take out the aluminum sheet in a vacuum oven at 30°C Bake in a medium (vacuum degree of -750mmHg) for one hour and take it out to obtain a phthalocyanine film.

Abstract

A preparing method for phthalocyanine film includes such steps as: 1) putting phthalocyanine into solvent as mass ratio of 1:1000 to 100000 for mixing to obtain phthalocyanine solution with solid content of 0.001%-0.1% by mass and 2) immersing baseplate into the above-mentioned phthalocyanine solution and carrying on the external field action for one minute to one hour for obtaining the phthalocyanine film on the baseplate, furthremore obtaining the dried phthalocyanine film in thickness of 10nm to 1 mum by removing the solvent.

Description

Technical field [0001] The invention relates to a method for preparing a phthalocyanine film. Background technique [0002] In recent years, with the development of information science and material science, organic optoelectronic materials have received increasing attention, and its research and development has become a hot topic in international research. Phthalocyanine is a kind of promising organic optoelectronic materials. It is expected to be widely used in organic transistors, solar cells, electroluminescent devices, nonlinear optics, optical recording and storage, chemical dyes, electrophotographic photosensitive drums, and gas-sensitive sensor devices. Application prospects. For example, researchers from Lucent Company reported on Nature that organic transistors can be fabricated from materials such as perfluorocopper phthalocyanine and polythiophene, so that large-scale integrated circuits can be manufactured; in recent years, based on the conjugat...
