Abstract :
A new 2,3-dibutoxy-l,4-phenylene vinylene is reported with high photoluminescence (40%) and electroluminescence efficiencies. The unusual substitution pattern is effective in tuning the emission colour as the polymer exhibits unexpected blueshifted emission to the green region. Crystal structures of model oligomers (PL efficiencies 80%) and theoretical calculations on optimised geometry offer insight into these interesting properties.
