本文综述了在分子电子学和光电子学等领域具有潜在应用前景的杂环稠联联苯材料的合成和性能研究进展。这种相当年轻的有效调节电子性质的策略产生了具有非常窄带隙的材料。中心桥联杂原子的性质对这些材料的电子和发光性能产生了重大影响，导致了可用于有机发光二极管(OLED)或有机场效应晶体管(OFET)的有趣物种。到目前为止，已研究了13-16族的各种杂元素(B、Si、Ge、Sn、N、P、S)，并将它们融入到分子和聚合物体系中。这些材料中有相当一部分可能在有机器件中作为有机发射体、电子或空穴传输材料，但需要进一步的研究来优化这种年轻的化合物在分子电子学中的应用所需的性质。
This article covers the developments on the synthesis and properties of heterocyclic fused pi-conjugated bithiophene materials that are potentially applicable in molecular electronics and optoelectronics. This fairly young strategy to efficiently tuning the electronic properties generates materials with very narrow band gaps. The nature of the central bridging heteroatom has a significant impact on the electronic and luminescence properties of these materials leading to intriguing species that can be employed in organic light emitting diodes (OLEDs) or organic field effect transistors (OFETs). So far a variety of heteroelements of group 13-16 (B, Si, Ge, Sn, N, P, S) have been investigated and incorporated into molecular as well as polymeric systems. A significant number of these materials can potentially act as organic emitters, electron or hole transport materials in organic devices but further studies are needed to optimize the necessary properties for the utility of this young class of compound in molecular electronics.
