纯有机化合物的磷光

Organic compounds include purely organic compounds and metal complexes and their luminance includes fluorescence and phosphorescence. Although phosphorescence is very useful, phosphorescence from purely organic compounds is regarded impossible by a century's modern chemistry and physics and only after the organic ligands coordinate with heavy metals or rare earths, can the complexes emit efficient phosphorescence by spin-orbit coupling. In early 2013, we found that one purely organic compound emits 6% phosphorescence. Since then, three years passed with our hard work. We now obtained 100% phosphorescence from purely organic compounds. By careful examination and re-examination, based on the luminance life time, the emission spectra and device efficiency, it is proved as phosphorescence, not fluorescence. Since October 2015, we have been tried to get the results published in science magazines and patents while the mechanism has been re-corrected. This application is proposed just based on the hard work and achievements of the past three years luckily led by two major occasional discoveries. By the support of the upcoming foundation, we will study the basic scientific mechanisms of phosphorescence from purely organic compounds, obtain more experimental supports for the excited state, discover the deep hided mechanism, harvest good materials, so that we can contribute greatly to the development of organic photochemistry and photophysics and organic display and white-lighting.

有机化合物包括纯有机化合物和金属配合物，其发光包括荧光和磷光。尽管对磷光的需求非常迫切，长期以来的有机发光理论都认为，纯有机化合物只能发荧光，只有在和重金属或稀土金属配位得到金属配合物后才有可能引发自旋-轨道偶合而发磷光。2013年初，我们实验室发现纯有机化合物能发6%的磷光。之后经过近三年的努力，我们得到了能发100%磷光的化合物，这可以从发光寿命、发光光谱、器件效率三个方面证实是磷光而非荧光。从2015年10月份开始，进行专利申请和论文发表并不断修正机理模型。本基金申请是在过去三年由两次偶然发现而引导的艰难的实验研究成果基础上提出来的。在本基金资助下，我们将进一步研究纯有机化合物发磷光的基本科学问题，寻求更多关于磷光激发态的实验证据，揭示有机磷光的深刻机理，得到性能更好的有机材料，为有机光化学与光物理的基础理论和有机光电显示与白光照明的实践做出更大的实质贡献。

本项目以纯有机化合物的磷光为研究内容。由于目前世界上还未有纯有机的磷光材料，所以，必须对最基本的有机发光原理有深刻的理解才能最终解决问题。而这种深刻的理解需要从理论、实验、推理、验证这几个方面入手。本课题从未申请基金的2013年就已经开始，历经8年的研究，在2021年计划提交论文。其中在2015年，曾提交过论文，但由于实验验证不完全，未发表。.通过对含羰基的有机物、纯碳氢化合物、8-羟基喹啉-金属化合物、重金属配合物、含氰基化合物、纯有机化合物这几大类化合物的荧光和磷光的研究，基本上得出了有机发光的新机理。这一新机理完全不同于基于分子轨道和Jablonski的能量曲线的传统理论。
