Azulene has a considerably larger dipole moment than its isomer naphthalene; it also has unique physicochemical properties, including different reactivities on five‐ and seven‐membered rings, a dark color, a narrow gap between the highest occupied molecular orbital and lowest unoccupied molecular orbital, and stimulus response. Although azulene was discovered more than 100 years ago, the use of azulene‐based derivatives can be traced back to five centuries ago. Due to its unusual structure, azulene‐based molecules and materials are widely used in various fields. However, studies on azulene‐based materials have long been hindered by difficulties in the synthesis. Considerably fewer studies have been conducted on azulene‐based derivatives than on naphthalene‐based derivatives. This perspective paper mainly introduces recent reports on the synthesis of azulene‐based aromatic molecules, conjugated polymers, and coordination polymers, in addition to azulene‐based frameworks. The structure–property relationship, optoelectronic applications, and energy‐related applications of azulene‐based derivatives are reviewed, including their use in near‐infrared absorption, organic field‐effect transistors, organic solar cells, and microsupercapacitors.

用于光电子和能源应用的基于Azulene的分子，聚合物和框架

Azulene的偶极矩比异构体萘大得多。它还具有独特的理化特性，包括在五元和七元环上具有不同的反应性，深色，在最高占据分子轨道与最低未占据分子轨道之间的狭窄间隙以及刺激反应。尽管在100年前就发现了azulene，但基于azulene的衍生物的使用可以追溯到五个世纪前。由于其独特的结构，基于z的分子和材料被广泛用于各个领域。但是，长期以来由于合成困难，阻碍了基于a烯材料的研究。与基于萘的衍生物相比，针对基于z烯的衍生物进行的研究要少得多。本观点论文主要介绍了基于氮杂骨架的最新报告，涉及基于氮杂芳族分子，共轭聚合物和配位聚合物的合成。综述了基于氮杂的衍生物的结构-性质关系，光电应用和与能源有关的应用，包括它们在近红外吸收，有机场效应晶体管，有机太阳能电池和微型超级电容器中的使用。
