Abstract
The synthesis of new boron-containing acenes (meta-B-entacenes) is reported. These compounds exhibit slightly non-planar core geometries with blue-shifted spectral properties and more negative electrochemical reduction potentials relative to known para isomers. Polarizable π-extended architectures were realized via cross-coupling procedures with chloro-functionalized precursors.
摘要
本文报道了新型含硼薁（间位-B-薁）的合成。与已知的对位异构体相比，这些化合物具有略微非平面的核心几何形状，光谱性质蓝移，电化学还原电位更负。通过与氯官能化前体的交叉偶联程序实现了可极化的π-扩展架构。
