Azobenzenes (Ph-N═N-Ph) are known as the most widely studied molecular photoswitches, and recent rise of azoheteroarenes (Het-N═N-Ph or Het-N═N-Het) offers great opportunities to advance this already mature field. A common limitation is that azo-switches generally require harmful UV light for activation, which hinders their application across various fields. Despite efforts in developing visible-light azobenzenes over past few decades, potential heteroaryl azoswitches remains largely unexplored. This Perspective summarizes state-of-the-art advancements azoswitches, covering design strategies, structure-property relationship, applications. We highlight distinctive advantages research development switches. Furthermore, we discuss challenges emerging field propose solutions address crucial issues such spectral red-shift thermal half-life. Through paper, aim provide inspiration further exploration field, anticipation growing prosperity bright future azoheteroarene photoswitches.

Abstract Azobenzene and its derivatives are the most extensively investigated applied molecular photoswitches, which can undergo reversible transformation between trans cis isomers upon irradiation with light at specific wavelengths. Through structural geometry transformation, property alterations be integrated into smart materials to meet diverse application requirements. Most azo‐based photoswitches require UV for activation. However, complete activation within visible or even near‐infrared range could offer several benefits photoswitch applications, including improved biocompatibility, better penetration, enhanced solar utilization efficiency. This review presents an overview of development visible‐light responsive materials, covering design strategies their applications in energy storage. Recent efforts aimed enhancing performance storage highlighted. According different improving properties, these categorized as those that directly increase isomerization introduce phase transition energy. Furthermore, we discuss challenges opportunities this field a view inspire further exploration.
