HOMOGENEOUS LIGHT-INDUCED ELECTRON-TRANSFER BETWEEN 9,10-ANTHRACENEDIONE AND SODIUM TETRAPHENYLBORATE - A CHANNEL ELECTRODE STUDY

The electron transfer between excited-state 9,10-anthracenedione (325 nm) and sodium tetraphenylborate (tetraphenylboron sodium) in acetonitrile solution is shown to form the radical anion of 9,10-anthracenedione together with the BPh4. radical. The latter is known to decompose to biphenyl and other products. A new channel electrode methodology is developed and characterized to deduce the mechanism of the reaction and to quantify its kinetics.
