Abstract
Abstract Due to the numerous biological as well as pharmacological activities of 1,2,4-triazine derivatives, we reported a synthesis of novel series of bis(5,6-diphenyl-1,2,4-triazines) via alkylation of 5,6-diphenyl-1,2,4-triazine-3(4H)-thione with the appropriate bis(halo) compounds in ethanolic KOH. The chemical structures of these compounds were confirmed by spectroscopic techniques. The absorption and excited-emission spectra of the studied novel series were monitored experimentally in ethanol solvent. The molecular structures of these triazines were optimized using B3LYP/6–31G(d) level of theory. The electronic absorption and emission spectra of the novel compounds, in gas and ethanol solvent, were calculated using time dependent density functional theory (TDDFT) at mPW1PW91/ 6–31 G (d) level. The obtained theoretical results were compared to experimental ones. The results show that, the computational optical properties of the studied novel series are in agreement with experimental results.
