A new procedure for the synthesis of azo dyes based on 8-methoxy-2,2,4-trimethyl-1,2-dihydroquinoline and 1- or 2-substituted tetrazoles results in a crucial increase in the yields of the target compounds. The structures of the synthesized dyes containing Me, But, and Ad substituents at the 1 and 2 positions of the tetrazole moiety were established by NMR spectroscopy and X-ray diffraction analysis. The most stable conformations of the dyes depending on the substituent and the solvent were determined. The electronic absorption spectra in different solvents were characterized experimentally and theoretically.
