The nanoparticles of oxotitanium phthalocyanine(TiOPc) synthesized from titanium tetra-n-butoxide and 1,3-diiminoisoindole were prepared by liquid phase method using surfactant polyethylene glycol as a coating agent. The effects of surfactant type, content, preparation temperature and drying method were examined. When the mass ratio of polyethylene glycol to original TiOPc was 1:10, at ice bath temperature and by vacuum freeze drying method, TiOPc particles of 60 nm size were obtained. The product appeared to be an excellent photosensitive material with saturation potential of 540 V, residue potential of 20 V, half life of 0.2 s, and half discharge energy of 0.6l x·s.
