Abstract

Polyamine dendrimers functionalized with electrochemiluminescent (ECL) polypyridyl Ru(II) complexes, dend-[CO-(CH2)3- mbpy·Ru(L)2]3(PF6)6 (dend: N(CH2CH2NH)3-, L: bpy, o-phen, phen-Cl, DTDP), were synthesized through the complexation of dendritic polypyridyl ligands to Ru(II) complexes. Their electrochemical redox potentials, photoluminescence (PL), and relative ECL intensities were studied. The ECL emissions produced by the reaction between the electro-oxidized Ru3+ species of polyamine dendrimers and tripropylamine as a coreactant were measured in a static system with potential cycles between 0.8 and 1.3 V or through flow injection analysis with a potential of +1.3 V, and were compared to that of [Ru(o-phen) 3](PF6)2. Dend-[CO-(CH2) 3-mbpy·Ru(bpy)2]3(PF6) 6 showed an ECL intensity that was two-fold greater than that of the reference complex [Ru(o-phen)3](PF6)2.
