Sixteen p-phenylenevinylene oligomers (OPVs) substituted with different electron-donating (ED) and electron-withdrawing (EW) groups were synthesized by the Mizoroki-Heck cross coupling reaction in moderate to good yields (40-95%), and with a totally trans-trans configuration in the vinyl bonds, which is difficult to obtain following common synthetic methodologies. Their structures were stablished by spectroscopic methods (FT-IR, 1H, 13C and Solid-State NMR), elemental analysis, and by mass sp...
