Abstract

The effects of processing temperature on the oxygen quenching behavior of tris(4,7′-diphenyl-1,10′-penanthroline) ruthenium (II) [Ru(dpp)₃]²⁺ sequestered within sol-gel-derived xerogel thin films were studied. It is demonstrated that there is an increase in the sensitivity of the [Ru(dpp)₃]²⁺ molecules to O₂ quenching when the films have been cured at elevated temperatures. This arises because there are two main types of [Ru(dpp)₃]²⁺ microenvironments within the glass and higher temperature curing leads to an increase in the bimolecular quenching rate between O₂ and [Ru(dpp)₃]²⁺.
