Abstract
5-(Phenylethynyl)-2'-deoxyuridine ((Ph)U) 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 (Ph)Us were observed using 5-bromouracil as a distal electron trap.
摘要
5-(苯乙炔基)-2'-脱氧尿苷((Ph)U) 被连续掺入寡脱氧核苷酸中，作为调节 DNA 介导的过量电子转移 (EET) 的电子传递调节剂。在乙炔基芘发色团光激发时，使用 5-溴尿嘧啶作为远端电子捕获剂，观察到含有连续(Ph)U 的 DNA 具有极高的 EET 效率。
