Abstract: Functional phthalocyanine (Pc) compounds of H2Pc, TiOPc, FePc and ClAlPc were synthesized with a yield of 46.7%, 91.2%, 37.4% and 34.0%, respectively. Nanosized TiOPc was synthesized via a one-step sol-gel method and effects of surfactant doses, nucleation temperature on TiOPc particle size and photoconductivity were investigated. When m(PEG): m(TiOPc) was 0.1 and nucleation temperature was 0℃, the as-obtained TiOPc had the smallest particle size and largest specific surface area, which were 60~nm and 83 m2/g, respectively. TiOPc synthesized under these conditions also exhibits excellent photoconductivity with charging potential V0, dark decay speed Rd and energy for half-discharging of potential E 1/2 being 1160 V, 30 V/s and 0.6 lx•s, respectively.
