摘要：

A TiO2 nanocrystallite has been modified to selectively bind, by complementary hydrogen bonding, a uracil substrate incorporating a viologen moiety. Bandgap excitation of the self-assembled donor (TiO2 nanocrystallite)-acceptor (viologen) complex results in electron transfer. Some implications of these findings for the self-assembly of functional nanostructures containing both condensed phase and molecular components are considered.
