Ladder pi-conjugated compounds, which have fully ring-fused polycyclic skeletons, are an important class of materials possessing significant potentials for application in organic electronics. The incorporation of main-group elements, such as B, Si, P, S, and Se, into the ladder skeletons as bridging moieties is a powerful strategy to endow unusual electronic structures as well as suitable molecular arrangements in the solid state, giving rise to attractive photophysical and electronic properties. Recent efforts have produced a number of fascinating ladder materials, some of which indeed showed high performance as light-emitting materials and charge carrier transporting materials. This Focus Review is an overview of the progress in this chemistry, focusing on several important pi-conjugated skeletons.
具有完全稠环多环骨架的梯形π共轭化合物是一类重要的材料，在有机电子学中具有巨大的应用潜力。将主族元素（如B、Si、P、S和Se）作为桥连部分引入梯形骨架是一种强有力的策略，可赋予其异常的电子结构以及固态下合适的分子排列，从而产生吸引人的光物理和电子性质。最近的研究成果已制备出许多引人入胜的梯形材料，其中一些确实表现出作为发光材料和电荷载流子传输材料的高性能。本重点综述概述了该化学领域的进展，重点关注几种重要的π共轭骨架。
