ʻO ka europium(III) a me ka terbium (III), ʻo ia hoʻi [Eu(dpq)(DMF)2(NO3)3] (1), [Eu(dppz)2(NO3)3] (2), [Tb(dpq )(DMF)2Cl3] (3), a me [Tb(dppz)(DMF)2Cl3] (4), kahi dipyrido[3,2-d:2',3'-f]quinoxaline (dpq i 1 a me 3) , dipyrido [3,2-a: 2', 3'-c] phenazine (dppz ma 2 a me 4) a me N, N'-dimethylformamide (DMF) i hoʻokaʻawaleʻia, iʻikeʻia mai kā lākouʻikepili physicochemical, luminescence study a me kā lākou pilina. me DNA, serum albumin protein a me ka photo-induced DNA cleavage activity e aʻo ʻia.Hōʻike ʻia nā hale aniani X-ray o nā paʻakikī 1-4 i nā hale kūʻokoʻa mononuclear Ln(3+).ʻO ka Eu(3+) ma [Eu(dpq)(DMF)2(NO3)3] (1) a me [Eu(dppz)2(NO3)3] (2) e like me [Eu(dppz)2(NO3)3 ]·dppz (2a) apono i ka ʻumi-coordinated bicapped dodecahedron hale me ka bidentate N,N-donor dpq ligand, ʻelua DMF a me ʻekolu NO3(-) anions i 1 a me ʻelua bidentate N,N-donor dppz ligand a me ʻekolu NO3( -) nā anion ma 2. Hōʻike ka paʻakikī 3 a me 4 i kahi ʻano octahedron mono-capped ʻehiku i hui pū ʻia ma kahi o Tb(3+) i loaʻa i nā ligand bidentate dpq/dppz, ʻelua DMF a me ʻekolu Cl(-) anion.ʻO nā complexes he luminescent nui ma ke ʻano e hōʻike ana i ka hoʻololi ʻana i ka ikehu hoʻohiwahiwa kiʻi maikaʻi mai ka antenna dpq/dppz i Ln(3+) e hoʻohua i nā mokuʻāina emissive hauʻoli lōʻihi no ka hoʻololi ʻana f → f.Hōʻike ka ʻano luminescence i hoʻoholo ʻia i ka manawa o nā paʻakikī 1-4 i nā ʻāpana hoʻokuʻu haiki maʻamau i pili i ka (5)D0 → (7)F(J) a me (5)D4 → (7)F(J) ff hoʻololi o Eu(3 +) a me nā ion Tb(3+).Hoʻoholo ʻia ka helu o nā molekole wai i loko o ka pōʻaiapili (q) mai nā ana o ka luminescence i ka H2O a me D2O e hōʻoia ana i nā hopena hoʻololi ligand me ka wai i ka hopena.Hōʻike nā paʻakikī i ka manaʻo hoʻopaʻa paʻa nui i ka CT-DNA e hāʻawi ana i nā waiwai paʻa mau i ka laulā o 1.0 × 10(4) -6.1 × 10(4) M(-1) ma ke kauoha 2, 4 (dppz) > 1, 3 (dpq).Hōʻike ka ʻikepili hoʻopaʻa DNA i ka hoʻopaʻa ʻana i ke awāwa DNA me ke ʻano intercalation hapa o nā paʻakikī.Hōʻike pū nā mea paʻakikī a pau i ka makemake paʻa (K(BSA) ~ 10(5) M(-1)) i ka protein serum albumin (BSA) bovine.Hoʻonui nui ʻia ka ikaika o nā puʻupuʻu luminescence i hoʻopaʻa ʻia i ka manawa me ka piʻi ʻana o ka ʻike DNA i loko o ka wai paʻa wai ma muli o ka neʻe ʻana o ka wai i hoʻopaʻa ʻia ma ka launa pū ʻana me DNA, pēlā e hōʻemi ai i ka hoʻopau ʻole-radiative ma o ka OH oscillator.Hoʻopili maikaʻi nā complexes 1-4 i ka supercoiled (SC) ds-DNA i kona ʻano pōʻai nicked (NC) ma ka ʻike ʻana i ke kukui UV-A o 365 nm ma o ka hoʻokumu ʻana o ka oxygen singlet ((1)O2) a me nā radical hydroxyl (HO˙) e like me nā ʻano oxygen reactive ma nā ʻano micromolar ma lalo o nā kūlana physiological.
