Abstract

A method of synthesis of the allyl-containing azobenzene chromophore with a hydroxymethylene group is developed by the reduction of an aldehyde group of 5-[2-phenyldiazene-1-yl]-2-(prop-2-en-1-yloxy)benzaldehyde. Organic-inorganic hybrid nanoparticles containing the azobenzene chromophore with a hydroxymethylene group in the organic part of the core are obtained by the interaction of the synthesized azochromophore with octakis(dimethylsilyloxy)silsesquioxane. The synthesized compounds were characterized by 1H, 13C NMR, IR and UV-vis spectroscopy techniques and can be considered for photoswitches, sensing devices, nonlinear optic and liquid crystal materials.
