By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Macromolecular Research. According to news reporting originating in Stillwater, Oklahoma, by NewsRx journalists, research stated, "A modular approach for the synthesis of polymer networks with well-defined node and cross-linking dimensions is described. Each node or tie point in the network is a cyclodextrin molecule, which imparts discrete molecular guest-host capabilities to the network."
The news reporters obtained a quote from the research from Oklahoma State University, "C-60 fullerenes homogeneously intercalate in the network, presumably via van der Waals guest-host interactions with the hydrophobic gamma-cyclodextrin cavity, resulting in stable C-60-filled polymer networks with improved mechanical properties. Networks prepared with alpha-cyclodextrin, whose inner cavity is smaller than gamma-cyclodextrin, and smaller than the C-60 diameter, do not yield materials with stable C-60 intercalation. Characterization of the final composites reveals that the cross-linked gamma-cyclodextrin-based composites maintain stable C-60 concentrations, even after multiple extractions with toluene, which itself is a good solvent for C-60. Membranes prepared from the cyclodextrin polymer network, prior to C-60 intercalation, should also be useful for C-60 extraction from C-60-solvent mixtures."
According to the news reporters, the research concluded: "The synthetic route we describe here is not limited to C-60 and should be generally applicable to a wide variety of guests."
