Abstract

5-(Phenylethynyl)-2′-deoxyuridine (PhU) was consecutively incorporated into oligodeoxynucleotides as an electron transport modulator for regulating DNA-mediated excess electron transfer (EET). Upon photoexcitation of the ethynylpyrene chromophore, extremely high EET efficiencies through DNA containing consecutive PhUs were observed using 5-bromouracil as a distal electron trap.
