Polymeric schiff's base chelates and their precursors, 9. Synthesis of covalently and coordinatively bound polymeric chelates and their dioxygen binding in the solid state

Abstract

Abstract Covalently bound polymeric cobalt chelates 5 of Co(salen) type were synthesized by copolymerization of 2‐hydroxy‐5‐vinylbenzaldehyde ( 2 ) with 4‐vinylpyridine and subsequent polymeranalogous reactions. Coordinatively bound polymeric chelates 6 were obtained from Co(salen) and poly(4‐vinylpyridine) or its copolymer with styrene. Dioxygen binding studies (volumetric measurements and ESR spectroscopy) revealed that mononuclear superoxo complexes are formed reversibly.
