Abstract: Oxotitanium phthalocyanine was synthesized from phthalonitrile and titanium te-trachloride in bicyclohexyl.It is much more convenient to separate and purify the productsby using bicyclohexyl as a solvent. Five polymorphs were obtained and characterized by X-ray powder diffractometry and FTIR spectroscopy. The absorption spectra of the poly-morphs in silicone rubbers were recorded.

Key words: oxotitanium phthalocyanine, synthesis, crystal form, organic photoconductor
