This study investigates the optical limiting potential of 3-[(2-chlorophenyl)diazenyl]pyridine-2,6-diamine (1od). Azobenzenes, recognized for reversible photoinduced isomerization and versatile applications in molecular switches, share structural similarities with Azopyridine (AzPy). Despite AzPy's underexplored status, its push-pull character enhances nonlinear optical properties, particularly in absorbing and dissipating high-intensity laser light. Employing experimental and theoretical analyses, including the Z-scan technique and density functional theory, the study highlights 1od’s promising prospects as an optical limiter.

3-[(2-氯苯基)二氮烯基]吡啶-2,6-二胺作为光学限制剂的实验和理论研究

本研究研究了 3-[(2-氯苯基)二氮烯基]吡啶-2,6-二胺 ( 1od ) 的光学极限电位。偶氮苯因可逆光致异构化和在分子开关中的多种应用而闻名，与偶氮吡啶 (AzPy) 具有结构相似性。尽管 AzPy 尚未得到充分开发，但其推挽特性增强了非线性光学特性，特别是在吸收和耗散高强度激光方面。该研究采用实验和理论分析，包括 Z 扫描技术和密度泛函理论，强调了1od作为光学限制器的广阔前景。
