Photo‐ and electroluminescence efficiency in soluble poly(dialky1‐<i>p</i>‐phenylenevinylene)

Efficient green electroluminescence from PPV derivatives that are readily processible in the conjugated state is reported. Derivatives of poly( p ‐phenylenevinylene), PPV, offer possible ways of controlling the emission color, facilitating processing, and enhancing the emission efficiency. The synthesis of soluble poly(dialky1‐ p ‐phenylenevinylene) is described and the dependence of the efficiency of photoluminescence and electroluminescence on the degree of conjugation 1s discussed.
