A series of 1,3,5-triazines were synthesized and their UV absorption properties were tested. The computational chemistry methods were used to construct quantitative structure-property relationship (QSPR), which was used to computer aided design of new 1,3,5-triazines ultraviolet rays absorber compounds. The experimental UV absorption data are in good agreement with those predicted data using the Time-dependent

These materials are endowed with narrowed singlet−triplet splitting energy (ΔEST), efficient reverse intersystem crossing (RISC) process, and
用于有机发光二极管 (OLED) 的激基复合物的探索已迅速发展。然而,它们中的许多都面临着相分离和溶解度差等问题,阻碍了它们在溶液过程中的应用。因此,合成并表征了一系列具有简单结构的 D-spacer-A(mCP-6C-TRZ、phCz-6C-TRZ 和 2phCz-6C-TRZ)的可溶性激基复合发光体,其中,烷基链为充足的间隔物破坏分子骨架共轭,诱导分子间电荷转移过程,而不是固态分子内电荷转移。这些材料被赋予了狭窄的单线态-三线态分裂能(ΔE ST)、高效的反向系统间交叉 (RISC) 过程和独特的热激活延迟荧光 (TADF) 特性。鉴于它们的高三重态能级 (E T ) 和双极载流子传输能力,在应用高效激基复合物作为主体的情况下,溶液处理的磷光器件在 1000 cd m -2 下实现了 7.0% 的低效率滚降,高亮度、电流效率 (CE) 和外量子效率 (EQE) 分别为 25,990 cd

carrier transport and balance properties. The mCP-3C-TRZ with nonane as the spacer shows better thermal stability and bipolar carrier transport ability, so the corresponding solution-processable phosphorescent organiclight-emittingdiodes exhibit superior external quantum efficiency of 9.8% when using mCP-3C-TRZ as a host material. This work offers a promising strategy to establish a bipolar host via
