In situ polymerization of xylylene bis(tetrahydrothiophenium chloride) yields a highly luminescent, yellow powder with a fluorescence spectrum matching that of unencapsulated PPV. Nitrogen adsorption isotherms show that the pore size of the PPV-loaded MCM-41 is significantly smaller than that of empty MCM-41 and a polymer loading of ca. 8\% by weight is obtained by thermogravimetric analysis. Photoluminescence data for the encapsulated PPV are presented.}, isbn = {1-55899-465-3}, issn = {0272-9172}, author = {Pattantyus-Abraham, AG and Wolf, MO}, editor = {Chalamala, BR and Friend, RH and Jackson, TN and Libsch, FR} }
