The MOF also discriminates between dimers consisting of alpha and beta linkages, showing no adsorption of maltose. Electronic structure calculations demonstrate that key to this selective molecular recognition is the number of favorable CH-pi interactions made by the sugar with pyrene units of the MOF.Royal Society of ChemistryJournal Articleapplication/pdfapplication/pdfhttp://hdl.handle.net/2115/65862https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/65862/2/ESI_0416my.pdfhttps://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/65862/1/manuscript_0418my.pdf1359-7345Chemical communications5244709470972016-06-04enginfo:doi/10.1039/c6cc03266dauthor
