Abstract

A long-term stable photoactive composition, such as a phosphorescent composition or a TTA-photon upconversion composition, contains at least one compound, which has a triplet state capable of energy transfer via an emissive process or a non-emissive process, and at least one compound capable of reacting with singlet oxygen, wherein the at least one compound capable of reacting with singlet oxygen comprises at least one terminal unsaturated carbon-carbon bond, and wherein the at least one compound capable of reacting with singlet oxygen is contained in the composition in such an amount that the number of terminal unsaturated carbon-carbon bonds is at least 100 times higher in the composition than the number of molecules of all compounds having a triplet state capable of energy transfer via an emissive process or a non-emissive process.
