摘要: A novel dye dimer, bis-{[1-(N-hexadecyl-4-pyridinium)-2-(4-N, N-dimethylamino-phenyl)] ethenyl}methane diiodide (C16BP) was synthesized, and the photoelectrochemistry of thedye Langmuir-Blodgett monolayer modified ITO electrode was investigated. For comparison, thephotoelectrochemistry of the monomer (E)-N-hexadecyl-4-[2-(4-N, N-dimethylaminophenyl)ethenyl] pyridinium iodide (C16P) was also measured. The results show that the photocurrentgeneration property of the dimer is enhanced. The photocurrent generation quantum yield is0.38% for C16BP, while that for C16P is 0.23%.
