Two pyrazine-containing conjugated copolymers (pyrazine-PPVs) were designed and synthesized to investigate their luminescence properties. The pyrazine-PPVs were synthesized using the Wittig reaction from 2,5-bis(bromomethyl)pyrazine triphenylphosphonium salt and the corresponding dialdehyde. A pyrazine unit was introduced to the main conjugated system to compare the luminescence shift du; to a change of the electron delocalization. A flexible long alkoxy chain was also introduced to maintain a desirable conjugation length. The introduction of pyrazine to the main chain resulted in a slight increase of effective conjugation length and exhibited the red shift in both the absorption and emission spectra.
