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

A soluble phthalocyanine-porphyrin complex (Lu(TBPor)Pc) has been rapidly synthesized from a lutetium porphyrin (Lu(TBPor)OAc) and a metal-free phthalocyanine (H-2(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, H-2(TBPc), and Lu(TBPor)OAc/H-2(TBPc) blend. Furthermore, we have also introduced a n-type photoconductor (N,N'-bis(1,5-dimethylhexyl)-3,4:9,10-perylenebis(dicarboximide)(PDHEP)) and TiO2 into Lu(TBPor)Pc photoelectric cell to fabricate a SnO2/Lu(TBPor)Pc + PDHEP + TiO2/Al photoelectric cell, exhibiting the largest short-circuit photocurrent (691.3 muA/cm(2)) among all of lab-made cells under illumination of white light (1.2 mW/cm(2)).
