Polymer Branch, WL/MLBP, Materials Directorate, Wright Laboratory, 2941 P Street, Suite 1, Wright Patterson Air Force Base, OH 45433-7750, USA High molecular weight sulpho-pendent poly(arylene ether ketone) homopolymers and copolymers were synthesized with inherent viscosities ranging from 0.94 dl g1 to 1.20 dl g1 and glass transition temperatures (Tgs) in the range 190200 °C. Their potential use as transparent matrix hosts for second-order NLO chromophores was explored from the point of view of obtaining monodisperse guesthost systems mediated by specific interaction between the sulphonic acid pendant of the polymer host and the basic functionality of the chromophore structure. Homogeneously dispersed, optically clear thin film composites were obtained for aromatic heterocyclic chromophores with electron-rich thienyl, N,N-dialkylamino or N,N-diphenylamino donors and a pyridyl acceptor in their molecular structures.
