Synthesis and Characterization of Poly(1,4-phenylene vinylene)-co-(2,5-pyridilene vinylene)’s

Abstract

The polymerizability of nitrogen-containing bissulfonium salts was analyzed. The<br />poor homopolymerization results were attributed to sluggish quinodimethane<br />formation. However, copolymerizations with the non-nitrogenated analogue<br />sulfonium salt were successful. We report here the synthesis and characterization of a<br />series of poly(1,4-phenylene vinylene)-co-(2,5-pyridylene vinylene)s. Elemental<br />analysis, FTIR, UV-vis and fluorescence studies demonstrate that the pyridilene units<br />can be incorporated by the water soluble precursor route in PPV-type polymers with<br />free-standing film formation properties.<br /><br />
