A phthalocyanine mixed crystal composed of at least two or more phthalocyanines selected from hydrogen phthalocyanine, copper phthalocyanine, titanyl phthalocyanine and vanadyl phthalocyanine is made to exist in water and/or an alcohol along with an organic solvent having a relative permittivity of 20 or less. The solution containing these components is optionally stirred and then allowed to stand as it is for a pre-determined period of time, whereupon the crystal structure of the phthalocyanine mixed crystal therein is converted. The phthalocyanine mixed crystal, of which the crystal structure has been converted, is washed with water or an alcohol, then filtered out and dried. The thus-obtained phthalocyanine photosensitive material is used to produce a photoreceptor, which can output digital signals at any time by digital inputting or analogical inputting. Therefore, the photoreceptor can be used in digital recording photography and also as a conventional analogical input photoreceptor to give high-quality images having sharp edges.

Thin film, n-channel transistors in which the active layer is an ordered film of a substituted phthalocyanine coordination compound with a field-effect mobility greater than 10-3 cm2/Vs and a conductivity in the range of about 10-9 S/cm to about 10-7 S/cm at 20°C are disclosed. Examples of suitable substituted phthalocyanines include copper phthalocyanine, zinc phthalocyanine, hydrogen phthalocyanine, and tin phthalocyanine in which the phthalocyanine has at least one fluorine or chlorine substituent on at least one of its six-membered rings. Thin film devices made of these materials have an on/off ratio of at least about 103. It is advantageous if the device is fabricated using a process in which the substrate is heated to a temperature in the range of about 30°C to about 215°C when the film is formed thereon.
