This review explores the advancements in the chemistry of higher acenes and their derivatives, with a focus on their synthesis, characterization, and potential applications. Historically, higher acenes have presented challenges to study due to their inherent instability and reactivity under ambient conditions. However, innovative synthetic strategies, including on-surface synthesis and the precursor approach, have significantly contributed to the ability to synthesize higher acenes even at preparative scales while evaluating their magnetic and semiconducting properties. Furthermore, ethynylene-bridged acene oligomers and polymers, known for their extended π-conjugated systems, have shown promise not only as semiconducting materials but also as topological materials. As synthetic methods continue to evolve and characterization techniques become more sophisticated, higher acenes offer exciting opportunities for progress in the fields of organic chemistry and materials science, paving the way for advanced applications in organic electronics.
本综述探讨了高级并苯及其衍生物的化学进展,重点关注其合成、表征和潜在应用。从历史上看,高级并苯由于其在环境条件下固有的不稳定性和反应性,给研究带来了挑战。然而,创新的合成策略,包括表面合成和前驱体方法,即使在制备规模下合成高级并苯并评估其磁性和半导体性质方面也做出了重大贡献。此外,以其扩展的π共轭体系而闻名的乙炔桥连并苯低聚物和聚合物,不仅作为半导体材料,而且作为拓扑材料都显示出了前景。随着合成方法不断发展,表征技术变得更加精密,高级并苯为有机化学和材料科学领域的进展提供了令人兴奋的机会,为有机电子学中的先进应用铺平了道路。
