The possibility of heterogeneous catalyst production based on immobilization of organometallic complexes of iridium (I) [Ir(COD)(IMES)Cl], [Ir(COD)(IMes)(OCH3)] and [Ir(COD)Cl]2 , [Ir(COD)(OCH3)]2 to the different nature supports (aminomethylpolystyrene, 3-aminopropyle-SiO2, ethylendiamine modified Merrifield peptide resin) was presented. As the result heterogeneous catalyst with the isolated iridium centers and with the ability of molecular hydrogen activation was synthesized. This catalyst was used for reversible activation of parahydrogen (SABRE process) which is allows to produce hyperpolarized labile ligand (pyridine). Moreover, the polarization transfer from 1H to 15N was done for the first for heterogeneous SABRE process. This heterogeneous catalyst was fully characterized by EXAFS, XANES, XPS, TEM and IR spectroscopy
