Application Progress of Pure Organic Room-Temperature Phosphorescent Materials

摘要:

室温磷光材料由于其独特的三线态发光机理，具有stokes位移大、激发态寿命长等特点，然而传统的室温磷光材料多含重金属原子，随之产生的生物毒性问题和环境污染问题限制了其应用。相比之下，纯有机室温磷光材料生产成本低，毒性小，可通过分子工程可对有机结构进行灵活的设计和修饰使其具有更丰富的发光特性，在防伪加密、有机电致发光、生物成像、传感检测等方面具有良好的应用前景，是无机磷光材料极具潜力的替代品，因而受到研究人员的广泛关注。本文总结了近年来纯有机室温磷光材料在防伪加密、有机电致发光、生物成像、传感检测等方面的研究进展，并对有机室温磷光应用尚待解决的问题与未来可能的发展方向进行了简要总结和展望。

Abstract:

Due to its unique triplet state luminescence mechanism, room temperature phosphorescent materials have the characteristics of large Stokes shift and long excited state lifetime. However, traditional room temperature phosphorescent materials mostly contain heavy metal atoms, resulting in biological toxicity and environmental pollution problems, which limit their application. Pure organic room temperature phosphorescence materials, by contrast, low production cost, low toxicity and can be through molecular engineering of flexible design and structure of organic modified to make it more luminous characteristics, in the security encryption, organic electroluminescent, biological imaging, sensing detection has good application prospect, is inorganic phosphor material potential substitutes, Therefore, researchers have paid much attention to it. In this review, we summarized the research progress of organic room-temperature phosphorescence (RTP) in anti-counterfeiting encryption, organic electroluminescence, biological imaging and sensing detection in recent years, briefly summarizes the problems, and outlook the possible development direction in the future.
