The syntesis methods of monoethers, monohydrazides, amido- and anilidoethers (AE), amido- and anilidohydrazides (AH) of imidazol-4,5-dicarboxylic acid (IDAH2) are improved. More than 20 samples are obtained, about 2 g each. All compounds are characterized by intense absorption in the UV and fluorescence, parameters of which depend on composition and structure of the compounds and the nature of solvent. The synthesis methods of complexes of corresponding AE and AH with lanthanides are optimized. For these complexes the 4f-luminescence is fixed in visible [Eu (III), Tb (III)] and IR-areas [Nd (III), Yb (III)]; quantum yields are measured. Influence of ligands structure and parameters of their fluorescence on 4f-luminescence characteristics of the obtained complexes is discussed. The synthesis method of crystal complexes IDAM (M = Cu, Co, Ni, Zn, Cd) and (AcO) 2Cu?AE (R = 2-, 3- and 4-MeOPh) is developed. It is found, that for the last complexes catalytic activity practically is absent.
