band gap: π‐conjugatedpentacene di‐, tri‐, and tetramers can be synthesized by using a versatile building block in Hay homocoupling as well as Cadiot–Chodkiewicz cross‐coupling reactions. This modularapproach allows the evaluation of solubility, stability, and the HOMO–LUMO gap as a function of compound length. Long‐range three‐dimensional π overlap occurs in the iBu3Si‐substituted pentacene dimer (see
注意带隙:可以通过在Hay均偶联以及Cadiot-Chodkiewicz交叉偶联反应中使用通用构件来合成π共轭并五苯二元,三元和四聚物。这种模块化的方法允许评估溶解度,稳定性和HOMO-LUMO间隙随化合物长度的变化。i Bu 3 Si取代的并五苯二聚体中发生长程三维π重叠(见图;n = 2)。
