Triplet states have been widely studied in phosphorescent molecules, lanthanide complexes and triplet–triplet annihilation systems, in which they have a critical role in energy transfer processes. However, advances have also shed light on their importance in organic–inorganic hybrid materials, wherein they can be used for decoding energy transfer mechanisms, enhancing interfacial energy transfer and attaining new properties. In this Review, we provide an overview of triplet properties, activation strategies and regulatory approaches. Our focus is on their crucial contribution to organic–inorganic hybrids, including inorganic semiconductor-sensitized triplet–triplet annihilation, the utilization of triplet reservoirs for thermally activated delayed photoluminescence, singlet exciton fission-induced silicon sensitization, dye-triplet-mediated upconversion nanoparticles, and other triplet systems. We discuss potential applications, exciting challenges, and opportunities for the advancement of triplet-mediated organic–inorganic hybrid materials.

三重态在磷光分子、稀土配合物和三重态-三重态湮没系统中得到了广泛的研究，它们在能量转移过程中发挥着关键作用。然而，进展也揭示了它们在有机-无机杂化材料中的重要性，其中它们可用于解码能量转移机制、增强界面能量转移并获得新性能。在这篇综述中，我们概述了三重态特性、激活策略和监管方法。我们的重点是它们对有机-无机杂化材料的关键贡献，包括无机半导体敏化三重态-三重态湮灭、利用三重态储库进行热激活延迟光致发光、单重态激子裂变诱导的硅敏化、染料三重态介导的上转换纳米颗粒、和其他三重态系统。我们讨论了三重态介导的有机-无机杂化材料的潜在应用、令人兴奋的挑战和发展机遇。
