An original strategy was set-up in order to develop new azo compounds which incorporate in their structure 4,4′-
diaminodiphenylmethane (DADFM) and low molecular weight maltodextrine. The synthesis of the model compounds involved the
functionalisation of DADFM with the maltodextrine, the conversion of amino functionalized maltodextrine in a diazonium salt and
the coupling of reaction with H and R acids. The compounds were characterized by UV-VIS, IR, mass spectroscopy and thermal
analysis. This new design unreported in literature will confer to the synthesized compounds a greater solubility, on the entire pH
range, which will result in an extended application field of these dyes, on various substrate types.
