Abstract

A donor-acceptor-donor molecule, PcZn-Pim-PcZn triad, which would be applied to improve the light absorption efficiency and achieve the efficient charge-separation states for appropriately long times, was prepared by reacting 3,4,9,10-perylene-tetracarboxylic dianhydride (Pim) with tBu₃(NH ₂)PcZn at 190 °C. The charge-separation process is anticipated to occur via the excited singlet state of the zinc phthalocyanines ( ¹PcZn*) and perylene (¹Pim*), depending on the excitation wavelength of the light used in polar and nonpolar solvents. The lifetime of the charge separated states was estimated as 20-25 ns.
