Molecular engineering and design of new controlled spatial assemblies and architectures is a field undergoing rapid growth.1 A large variety of disciplines, especially bioinorganic chemistry, are now taking profit from the design of molecular systems. Indeed, bioinorganic structural motifs can potentially model metalloenzyme structures and functions. The aim of such modeling is to mimic natural properties in order to elucidate fundamental aspects of reactivity and mechanism.The desire to mimic enzymatic systems has led to an active area of research involving synthetic porphyrin models of enzyme active sites, especially for monooxygenase enzymes of the cytochrome P-450.2™4 An analysis of comparative studies dealing with the selectivity, efficiency, and stability for both synthetic porphyrin models and natural systems has shown that efficiency arises from the control of the environment of the enzyme active site.4™7 Thus, in a first approach, the design of synthetic supramolecular architecture for porphyrin models with an elaborated steric environment (such as picnic basket porphyrins, strapped porphyrins, etc.) has been the subject of intense effort.8 A similar approach in concept that has been advanced during the last decade involves replacing of the protein envelope of natural enzymes by a mineral or organic polymeric matrix.9"18 This strategy is based on the fact that a polymeric matrix may provide the best arrangement for a catalytically active center as well as preventing autodestruction of the enzyme model Fethi Bedioui (born on
