Phthalonitrile, an alkali metal or an alkali metal compound, and a hydrogen donor compound are heated in an organic solvent to synthesize a partially hydrogenated alkali metal phthalocyanine, which is then brought into contact with a dealkalizing agent to effect substitution with hydrogen of the partially hydrogenated alkali metal phthalocyanine to thereby obtain high-purity metal-free phthalocyanine. FX-type metal-free phthalocyanine as obtained according to the foregoing procedure may be used as a charge-generating substance to produce an electrophotographic photoconductor of high image quality which is highly sensitive to near infrared rays.
在有机溶剂中加热邻苯二腈、碱金属或碱金属化合物和氢供体化合物,合成部分氢化碱金属酞菁,然后将其与脱醛剂接触,以实现部分氢化碱金属酞菁的氢置换,从而获得高纯度无金属酞菁。根据上述步骤获得的 FX 型无金属酞菁可用作电荷发生物质,以生产对近红外射线高度敏感的高 图像质量的电致发光光电导体。
