ABSTRACT The field of room temperature phosphorescence (RTP) from purely organic materials has made rapid strides in recent years primarily due to its tremendous promise in the areas of photovoltaics, photocatalysis, bioimaging, sensing, etc. Although, the RTP properties, at one time, were considered to be exclusive features of organometallic and inorganic phosphors, a great progress in the molecular design coupled with a much better understanding of the triplet state stabilisation has led to the creation of a plethora of organic RTP materials in the current decade. In this focussed review, a special category of organic luminogens which, rather remarkably, exhibit efficient RTP emission in amorphous or fluidic state is discussed. A few selected examples of such ‘non-crystalline’ organic RTP luminogens are highlighted with an emphasis on the basic design principles and the strategies to increment the phosphorescence efficiency.

“非晶态”有机发光体的室温磷光

摘要 近年来，由于其在光伏、光催化、生物成像、传感等领域的巨大前景，纯有机材料的室温磷光 (RTP) 领域取得了长足的进步。 ，被认为是有机金属和无机磷光体的独有特征，分子设计的巨大进步加上对三重态稳定性的更好理解，导致在当前十年中产生了过多的有机 RTP 材料。在这篇重点综述中，讨论了一类特殊的有机发光体，其在非晶态或流体态下表现出高效的 RTP 发射，相当显着。重点介绍了一些此类“非结晶”有机 RTP 发光体的选定示例，重点是基本设计原则和增加磷光效率的策略。图形概要
