Özet
Twelve new azocalix[6]arenes (1–12) have been synthesized by linking o-, m-, p-chloroaniline, o-, m-, p-nitroaniline, o-, m-, p-toluidine, m-, p-anisidine and aniline to calix[6]arene through a diazo-coupling reaction. The prepared compounds were characterized based on UV–vis, FT–IR and 1H-NMR spectroscopic techniques as well as elemental analysis. The effect of varying pH and solvent upon the absorption ability of azocalixarenes substituted with electron-donating and electron-withdrawing groups at their o-, m-, p-position was examined. Observed results were compared with those found for unsubstituted azocalix[6]arenes. Concentration effects on the visible absorption maxima of the dyes are also reported.
