| 英文摘要 | Six ru(ii)bis(tpy) (tpy = 2,2':6.2"-terpyridine) complexes, functionalized with one or two 2-naphthyl, 1-pyrenyl, or 9-anthracenyl at 4'-position of terpyridine respectively, were investigated with emphasis on their o-1(2) generation quantum yields and photocleavage capabilities on dna. for naphthyl and pyrenyl modified complexes, the lowest energy excited state is (mlct)-m-3, and therefore they behave very similarly to the parent complex, [ru(tpy)(2)](2+). having very low o-1(2) generation quantum yields. in contrast, for anthracenyl modified complexes, the lowest energy excited state is anthracene-localized (3)pi pi(*) state, as a result, they exhibit extremely high o-1(2) generation quantum yields (0.96 and 0.71 for bis- and mono-substituted complexes, respectively) and potent photodamage abilities on calf thymus dna, suggesting their promising applications in o-1(2)-involved processes, such as dna photocleavage.
