MOLECULAR ACCESSIBILITY IN INTERPENETRATING ORGANOMETALLIC POLYMER NETWORKS (IOPNS) - AN ESR EVALUATION

Interpenetrating organometallic polymer networks can be seen as a new type of supported metal catalysts. They are prepared by the generation of a cross-linked organometallic copolymer (see figure) inside the macro- and microporous domains of organic and inorganic supports. Here, ESR analysis demonstrates that the microporous domains of such materials are accessible to molecules of substantial size.
