Abstract

Abstract: The self-assembly of CBPQT and N-P₄-N has been well evidenced by 1HNMR,UV-vis and fluorescence measurements.Time-resolved spectroscopy revealed that photoinduced electron transfer from N-P₄-N to CBPQT takes place in this assembly with rate constant k_CS> 1.0×10⁸s^-1,charge recombination k_CR=1.26×10³s^-1,and the charge-separation has a life-time up to 794 μs in acetonitrile at room temperature.

Key words: supramolecular D-A system, photo-induced electron transfer, charge separation, viologen radical
