Paper Abstract

A novel soluble poly(phenylethanone) derivative grafted with tetra-acyl-chlorich manganese phthalocyanine (TACMnPc) was synthesized via esterification and characterized by electronic absorption spectrum and fluorescence spectra. The derivative (PPE-MnPc) exhibits high solubility and excellent film-forming property. Electronic absorption spectrum of the polymer exhibits a Q-band peak positioned at about 736 nm, which is obviously red shifted compared with 2, 9, 16, 23-tetra-carboxyl manganese(II) phthalocyanine (TCMnPc). PPE-MnPc films were prepared by dip-coating technology. Photoconductivity of PPE-MnPc films was characterized by current-voltage measurement. At bias voltage of 20 V, photoconductivity of the film was 6.8×10-9 S and dark conductivity was 7.5 ×10-10 S. The electrical conductivity of PPE-MnPc films under irradiation was nine times higher than that in the dark, which indicated that PPE-MnPc had a good photovoltaic response.
