Abstract

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.

有机-无机混合界面上的隐藏三重态
三重态在磷光分子、镧系元素复合物和三重-三重湮灭系统中被广泛研究,它们在能量传递过程中发挥着关键作用。然而,研究进展也揭示了它们在有机-无机杂化材料中的重要性,它们可用于解码能量传递机制、增强界面能量传递和获得新的特性。在本综述中,我们将概述三重态特性、活化策略和调控方法。我们的重点是三重子对有机-无机混合物的重要贡献,包括无机半导体敏化三重子-三重子湮灭、热激活延迟光致发光三重子库的利用、单激子裂变诱导的硅敏化、染料-三重子介导的上转换纳米粒子以及其他三重子系统。我们讨论了三重子介导的有机-无机混合材料的潜在应用、令人兴奋的挑战和发展机遇。
