heteroatoms such as thiophene, carbazole, and boron-dipyrromethene (BODIPY) have attracted increased attention because of their excellent optoelectronic properties in addition to the robust skeletons required for the construction of efficient organic electronics. Herein, novel π-extended polycyclic chromenopyridines 3a-d, 5, and 7 were synthesized via base-catalyzed cascade reaction of 3-cyano-7,8-benzochromone
掺杂噻吩、咔唑和硼-二吡咯亚甲基(BODIPY)等杂原子的多环芳烃(PAHs)除了构建高效有机电子器件所需的坚固骨架外,还因其优异的光电性能而受到越来越多的关注。在此,通过 3-氰基-7,8-苯并色酮1与乙腈衍生物2a-d、氯乙酸乙酯4和苯基吡唑啉酮6的碱催化级联反应,合成了新型 π 延伸多环色并吡啶3a-d、5和7产量非常好。化合物3a-d、5和7的密度泛函理论 (DFT) 计算和电化学评估显示,与前体 3-氰基色酮1相比,能隙 (E g ) 降低,表明它们具有出色的半导体和光捕获能力。此外,所观察到的色烯吡啶3a-d、5和7的热稳定性在 301.72 至 557.28 °C 的温度下具有最大的重量损失,使其适合广泛的有机电子应用。
