RUTHENIUM (II) COMPLEXES OF IMIDAZO-1,10-PHENANTHROLINES: HETEROGENEOUS ELECTRON TRANSFER AND GAS SENSORY PROPERTIES

Abstract

In this work, a series of imidazo[4,5-f][1,10]phenanthroline-containing ligands and their monoruthenium(II) and heterobimetallic complexes were synthesized (Fig. 1 left). These complexes are capable of photo-induced electron transfer to the conduction band of some semiconductor materials (Fig. 1 right). Such photosensitization process will reduce the operating temperature of semiconductor gas sensors and thus reduce their energy consumption
