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.
一种长期稳定的光活性组合物,如磷光组合物或 TTA 光子上转换组合物,包含至少一种化合物,该化合物具有能够通过发射过程或非发射过程进行能量转移的三重态,以及至少一种能够与单线态氧反应的化合物,其中至少一种能够与单线态氧反应的化合物包含至少一个末端不饱和碳-碳键、其中至少一种能与单线态氧反应的化合物在组合物中的含量,使组合物中末端不饱和碳-碳键的数量比所有具有能通过发射过程或非发射过程进行能量转移的三重态的化合物分子数量至少高 100 倍。
