New diazo macrocycles linked by hydrocarbon chain bearing imidazole or 4-methylimidazole residue have been synthetized with satisfactory yield (24–55%). The structure of macrocycles was confirmed by X-ray analysis and spectroscopic methods (1H NMR, MS, FTIR). Metal cation complexation studies were carried out in acetonitrile and acetonitrile-water system. It was found that azomacrocyles form triple-decker complexes with lead(II). The highest values of stability constant were found for lead(II) complexes of 21-membered derivatives. For the first time azomacrocycles bearing imidazole residue were immobilized on a porous glass. Obtained materials can act as lead(II) or copper(II) colorimetric optical sensors with color digital analysis as detection using simple portable devices.
