Advanced Polymer Synthesis and Characterization

Abstract A number of alternating copolymers containing anthryl and aryl units in the polymer chain have been prepared by Friedel‐Crafts arylation of the anthracene (polymer type B) or by condensation of 9,10‐bis(chloromethyl) anthracene with opportune aromatic substrates (polymer type A). Polymers of type A were all found to contain 9,10‐disubstituted anthracene units, but polymers of type B were found to contain 1,4‐disubstituted anthracene units. Structure of the polymers were established through their NMR and ultraviolet spectra, and through analogy with appropriate model compounds. It has been found that the inclusion of anthracene units in the polymer chain yields higher melting and more soluble materials with respect to polybenzyls containing only aryl units. Anthracene units introduce, also, some interesting fluorescence characteristics in the polymers, which show intense emission at about 440 mμ.
