摘要：

A new 2,3-dibutoxy-1,4-phenylene vinylene is reported with high photoluminescence (similar to 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 similar to 80%) and theoretical calculations on optimised geometry offer insight into these interesting properties.
