Synthesis of regioregular poly(methyl pyridinium vinylene): An isoelectronic analogue to poly(phenylene vinylene)

Poly(phenylene vinylene), PPV, and its derivatives have generated much interest due to their high conductivity and electroluminescent properties which allow for LED applications. Highly electron‐deficient PPV analogues are desirable as they would allow the use of environmentally stable metals as the electrodes in the LEDs. The title compound (see Figure) is just such as material. magnified image
