| Abstract;NAD+ analogues [1-benzylnicotinamidinium ion(BNA+) and 4-acetyl-N,N-diisopropyl-1-benzylnicotinamidinium ion(ABNA+)] form 1:1 complexes with scandium ion (Sc3+), which lead to a significant enhancement of electron transfer reduction of the NAD+ analogues. The electron transfer from decamethylferrocene [Fe(Cp*)2] to ABNA+ occurs efficiently in the presence of Sc3+, although no reaction takes place in the absence of Sc3+ under otherwise the same experimental conditions. The emission quenching occurs via electron transfer from excited state of Ru(bpy)32+ to the BNA+-Sc3+ complex. (author abst.) |
