Abstract

Water-soluble cationic conjugated poly(phenylene vinylene) (PPV) and cationic fullerene were complexed with negatively charged single stranded DNA and double stranded DNA via electrostatic interactions to achieve photoinduced charge transfer with efficiencies as high as those observed from oppositely charged, cationic PPV and anionic fullerene but with distinctly different quenching mechanisms.

摘要

水溶性阳离子共轭聚对苯撑乙烯（PPV）和阳离子富勒烯通过静电相互作用与带负电荷的单链DNA和双链DNA复合，以实现光诱导电荷转移，其效率与带相反电荷的阳离子PPV和阴离子富勒烯所观察到的效率一样高，但猝灭机制明显不同。
