Microwave-assisted synthesis of phthalocyanine-porphyrin complex and its photoelectric conversion properties

Abstract

A soluble phthalocyanine-porphyrin complex (Lu(TBPor)Pc) has been rapidly synthesized from a lutetium porphyrin (Lu(TBPor)OAc) and a metal-free phthalocyanine (H2(TBPc)) under microwave irradiation. Its photoelectric conversion properties have also been investigated. The experimental results reveal that Lu(TBPor)Pc exhibits better photoelectric conversion effect than Lu(TBPor)OAc, H2(TBPc), and Lu(TBPor)OAc/H2(TBPc) blend. Furthermore, we have also introduced a n-type photoconductor (PDHEP) and TiO2 have been blended into lab-made photoelectric cell with Lu(TBPor)Pc to exhibit the best photoelectric conversion effect with a short-circuit photocurrent (691.3 μA/cm2) among all lab-made cells under illumination of white light (1.2 mW/cm2). © 2004 Elsevieer B.V.
