Abstract
A possibility of using polyorganosiloxanes with incorporated metal complexes as models for active sites of metalloenzymes is discussed. Poly(3-aminopropyl)- and poly(3-aminopropyl, methyl)siloxanes containing incorporated hemin were obtained in the reaction of hydrolytic polycondensation. Results obtained by diffuse electron reflection and EPR spectroscopy demonstrate an influence of the surrounding matrix on the hemin coordination center, namely on the rhombic distortion of the ligand field.
