Chemically tuned zero-field splittings and spin-lattice relaxation - Investigation by time-resolved emission

Abstract

For the compounds studied, zero-field splittings (zfs) of the lowest triplets lie between about 0.1 and 200 cm⁻¹. This energy determines spin-lattice relaxation (slr) rates and thus time developments of the emission. It is possible to shift these relaxation
times into pre-defined time regions. The importance of these properties is demonstrated for the representative [Ru(bpy)₃]²⁺.
