The structure of the dopant creates a new type of supramolecular comb-shaped architecture in which the lateral groups, anions of the sulfophthalic acid residue, are ionically bonded to the main chain via protonation of ketimine nitrogen atoms. This specific interaction of the dopant with the host polymer influences the polyketanils' properties and the following changes were observed: decreasing glass transition temperature and improvement of polymer film flexibility, as well as a bathochromic shift of the photoluminescence emission band. © 2013 by Walter de Gruyter GmbH & Co.
