Preparation, catalytic activity of supported metalloporphyrin catalysts on polyvinylpyridine polymers and related molecular modelling studies (case of a proximal ligand provided by the polymer itself)

Anionic manganese and iron prophyrin complexes derived from sulfonated TPP, TMP or TDCPP ligands can be easily attached to a poly(4-vinylpyridinium) polymer . First the metalloporphyrin is linked to the neutral poly(4-vinylpyridine) by a pyridine from the polymer itself, which acts as a proximal ligand. The protonation of the other pyridine residues then reinforces the likage of metalloporphyrins by additional strong electrostatic interactions (molecular modelling studies confirm this hypothesis)
