Abstract
Emission properties of [Os(phen)₂(dppene)]²⁺ were investigated from 1.4 to 300 K in ethanol, PMMA, and PVK, a matrix which is frequently applied in OLEDs. These data provide the zero-field splitting values of the emitting T₁ state and the individual decay times of its substates. The T₁ state is assigned to be largely of MLCT character.

Abstract
Emission properties of [Os(phen)₂(dppene)]²⁺ were investigated from 1.4 to 300 K in ethanol, PMMA, and PVK, a matrix which is frequently applied in OLEDs. These data provide the zero-field splitting values of the emitting T₁ state and the individual decay times of its substates. The T₁ state is assigned to be largely of MLCT character. The splittings change only moderately due to variation of the
matrix, whereas the individual decay times are substantially affected. Further, energy transfer from the triplet state of PVK to [Os(phen)₂(dppene)]²⁺ was studied by applying time-resolved emission spectroscopy and is assigned to be dominantly of Dexter type.
