[(L2)2Rh(dppz)]Cl, [(L3)2Rh(dppz)](PF6), [(L4)2Rh(dppz)](PF6), and [(L8)2Rh(dppz)](PF6) – have confirmed the anticipated structure and have revealed the effect of substitution on the structure of the complex, which has been reasonably explained through experimental electrochemical characterization. The interaction of complexes 1–8 with calf thymus DNA (CT DNA) has been verified by the fluorescent detection of ethidium
一系列新的八面体的铑(III)络合物1 - 8的类型的[(L Ñ)2的Rh(dppz)] Cl(上Ñ = 1-6)和[(L Ñ)2的Rh(dppz)](PF 6) n = 1、7、8; L = 2-苯基吡啶,具有不同的修饰,作为C,N-螯合配体;和dppz = dipyrido [3,2-a:2',3'- c ]吩嗪}已被合成并充分表征。已经研究了配合物的光物理性质。五个配合物– [(L1)2 Rh(dppz)](PF 6),[(L2)2 Rh(dppz)] Cl,[(L3)2Rh(dppz)](PF 6),[(L4)2 Rh(dppz)](PF 6)和[(L8)2 Rh(dppz)](PF 6)–已经确认了预期的结构并揭示了取代对配合物结构的影响,这已经通过实验电化学表征得到了合理解释。配合物1 – 8的相互作用用小牛胸腺DNA(CT DNA)已通过荧光检测溴化乙锭(EB)的研究进行了
