Abstract: A series of electron donor-acceptor system linked by polyethylene glycol have been synthesized. The electron transfer fluorescence quenching of 9-aminoacridin was investigated, efficiencies and rate constants of electron transfer fluorescence quenching have been calculated.

Key words: polyethylene glycol, the donor-acceptor system, intramolecular electron transfer
