有机发光自由基研究进展
|
Abstract:
有机自由基分子因其独特的开壳性质，具有很好的反应活性，但也因此容易发生如抽氢、二聚化等反应，使自由基分子活性丧失。而1900年，三苯甲基自由基的首次报道证实了三苯甲基自由基分子可以稳定存在于室温中，拉开了研究自由基分子的序幕。在研究者持续的努力下，通过合理的分子设计使自由基分子能在室温下稳定存在，并且具有良好的荧光量子效率。发光自由基分子因为其独特的光、电和磁学等性质在诸多领域存在广泛的潜在方面。回顾总结关于有机发光自由基的研究发展现状。
Organic free radical molecules have good reactivity because of their unique shell-opening properties, but they are also prone to reactions such as hydrogen extraction and dimerization, which makes the activity of free radical molecules lose. In 1900, the first report of trityl radical confirmed that trityl radical molecules can exist stably at room temperature, which opened the prelude to the study of free radical molecules. With the continuous efforts of researchers, free radical molecules can exist stably at room temperature with good fluorescence quantum efficiency through reasonable molecular design. Luminescent radical molecules have a wide range of potential aspects in many fields because of their unique optical, electrical and magnetic properties. Review and summarize the research and development status of organic luminescent free radicals.
