Small organic molecules based on the unnatural DNA base pair dTPT3 are designed and synthesized, among which compounds bearing the thiocarbonyl group, compared with their carbonyl counterparts, show a much larger SOC integral between S(nπ*) and T(ππ*) states due to the appropriate energy level alignment and the heavy sulfur atom effect, resulting in the appearance of both fluorescence and phosphorescence in solution and solid state at room temperature.
基于非天然DNA碱基对dTPT3设计并合成了小分子有机化合物，其中含有硫羰基的化合物与其羰基类似物相比，由于合适的能级排列和重硫原子效应，在S(nπ*)和T(ππ*)态之间显示出大得多的单重态-三重态耦合积分，导致在室温下溶液和固态中均出现荧光和磷光。
