ligands at the cationic boron atom. UV‐vis absorption spectroscopy measurements and density‐functional (DFT) calculations show that these modulations are caused by changes in the geometry and extent of π‐conjugation of the boron formazanate ring. These findings suggest a new strategy for designing optoelectronic materials based on π‐conjugated heterocycles containing boron and other main‐group elements
将阳离子硼原子掺入分子框架是建立具有异常键合和反应性的化学物种的既定策略,但很少有人认为它是增强分子光电性能的一种方法。以甲maz硼酸硼染料为例,我们证明了BN杂环中第一个电子跃迁的波长,强度和类型可以通过改变电荷,配位数和阳离子硼原子上的配体来调节。紫外可见吸收光谱测量和密度泛函(DFT)计算表明,这些调制是由甲maz硼酸环的几何形状和π共轭程度的变化引起的。
