V approximately. Two fluoro groups were introduced on every vinyleneunits of m-SiP-PPV to give m-SiP-PPDFV in an attempt to increase the electron affinity of the parent polymer, and the devices show an increased colorstability even with vinyleneunits. The colorstability is attributed to the electron-withdrawing effect of the fluoro groups, which protect vinyleneunits from oxidation in PPV derivatives
