diboron-contained ladder-type π-conjugated compounds 1−4 were designed and synthesized. Their thermal, photophysical, electrochemical properties, as well as density functional theory calculations, were fully investigated. The single crystals of compounds 1 and 3 were grown, and their crystal structures were determined by X-ray diffraction analysis. Both compounds have a ladder-type π-conjugated framework. Compounds
四个含有二硼-梯型π共轭系化合物1 - 4设计并合成。对它们的热,光物理,电化学性质以及密度泛函理论计算进行了全面研究。生长化合物1和3的单晶,并通过X射线衍射分析确定其晶体结构。两种化合物均具有梯型π共轭骨架。化合物1和2具有高的热稳定性,中等的固态荧光量子产率以及稳定的氧化还原特性,这表明它们很可能是电致发光(EL)器件中的发射体和电荷传输材料的候选者。具有[ITO / NPB(40 nm)/ 1或2(70 nm)/ LiF(0.5 nm)/ Al(200 nm)]结构的双层器件具有良好的EL性能,最大亮度超过8000 cd / m 2。
