This study suggests that azoimidazole substitution is a better alternative to azobenzene derivatives for nonlinear optical responses. The synthesis, characterization, photophysical property and isomerization pathway of 2-[(E)-(4-fluorophenyl)diazenyl]-1H-imidazole (E-2g) are presented as an optical limiter through a comprehensive blend of experimental and theoretical approaches. Notably, E-2g exhibited a lower energy barrier than reported azobenzenes. The trans-to-cis photostationary state was reached in 75 min, while the cis-to-trans state was achieved in 60 min at 354 nm. The study further explores the photoisomerization pathway of E-2g, highlighting its nonlinear absorption, which has a nonlinear absorption coefficient (?eff) of 8.8 10?11 m/W at 20 ?J, as determined by Z-scan measurements. The results suggest that E-2g exhibits significant nonlinear absorption characteristics, which helps in applications requiring protection from intense light sources. This study explores the photoresponsive behavior of substituted azobenzenes derivative, azoimidazole, over unsubstituted azobenzene derivatives for nonlinear optical properties. Through experimental and theoretical analyses, the title compound was synthesized, characterized, and shown to have a lower energy barrier and efficient photoisomerization in solution. Its strong nonlinear absorption properties make it a promising candidate for optical limiting applications, such as eye protection and safeguarding sensitive optical sensors. 2025 World Scientific Publishing Company.
