A series of chloro-, fluoro-, and ester-substituted diphenyldiazene (azobenzene) dyes (1a–d and 2a–d) were synthesized and systematically investigated to evaluate the influence of substituent effects and solvent environment on their electronic and biological properties. UV–Vis spectroscopic studies revealed pronounced spectral response, indicating the significant role of solvent polarity and hydrogen-bonding interactions in modulating electronic transitions. Multiparametric analysis using Kamlet–Taft and Catalán models demonstrated that dipolarity/polarizability (π*) together with hydrogen-bond donor (α) and acceptor (β) interactions govern the observed solvatochromic behavior. Among the studied compounds, derivative 2d exhibited notable bathochromic shifts and enhanced intramolecular charge transfer (ICT) character in polar media. Additional absorption features in the 450–500 nm region may indicate possible tautomeric contributions or alternative electronic transitions in solution. Density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations, supported by frontier molecular orbital (HOMO–LUMO) analysis, provided insight into substituent-dependent electronic transitions and charge transfer characteristics. The synthesized compounds also demonstrated promising antibacterial and antifungal activities, with compound 2d showing the highest activity. Molecular docking studies further supported these findings by revealing favorable binding interactions with microbial protein targets. Overall, the results establish a clear relationship between molecular structure, solvent effects, electronic properties, and biological activity, offering valuable insights for the design of multifunctional diphenyldiazene dyes.
