Synthesis of new phenanthroline-based heteroditopic ligands – Highly efficient and selective fluorescence sensors for copper(II) ions
The heteroditopic phenanthroline derivatives 5,6-bis(2-pyridylcarboxamido)- 1,10-phenanthroline (H2L1) and 5,6-bis[(4-methoxy-2- pyridyl)carboxamido]-1,10-phenanthroline (H2L2) have been prepared and characterized, together with their luminescent ruthenium(II) complexes [Ru(bpy)2(H2L1,2)]-(PF 6)2 and [Ru(H2L1) 3](PF6)2 and the corresponding iron(II) complex [Fe(H2L1)3](PF6)2. In these complexes, the metal ion is coordinated by the bidentate phen site of H2L. The luminescence of the ruthenium complexes (lambda ex = 450 nm, lambdaemca. 620 nm) is completely quenched by Cu2+ ions in the micromolar concentration range and, to a lesser extent, by other metal ions. At pH 5, the response of the luminescent sensors is highly Cu2+-selective. Heterodinuclear complexes [Ru(bpy) 2(LM)](PF6)2, [Ru(LM)3](PF 6)2, and [Fe(LM)3](PF6)2 have been isolated for M = Cu2+, Ni2+, Co2+, and Pd2+. It is suggested that M is coordinated to the tetradentate N4 site of L by two deprotonated amide N atoms and two pyridyl groups. This coordination type is confirmed by the EPR spectrum of the compound [Ru II(bpy)2(L1CuII)](PF 6)2. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 15746-57-3, you can also check out more blogs about15746-57-3
