The synthesis and ion-binding properties of amide-based derivative of embonic acid and p-aminoazobenzene were described. The new compound was characterized by X-ray structural analysis and spectroscopic methods. Ligand interacts in acetonitrile with Y-shaped anions (benzoates and acetates) and dihydrogen phosphates forming complexes of 1:1 stoichiometry. In more polar DMSO the complexes stoichiometry changes to 2:1 (L:anion). Light-induced trans to cis isomerization was studied. The effect of anions on thermal back isomerization was investigated.
