A new series of stable, processable, and end functionalizable sulfone-derivatized phenylenevinylene based conjugated polymers (SFPVs) have been synthesized and characterized, where the polymer main chains are consisted of a sulfone-phenylene electron accepting unit coupled with an electron donating unit derived from one of the dialdehyde co-monomers based on benzene, thiophene, and pyrrole.  The solution optical energy gaps and the electrical energy gap (thin films) of these polymers are in the range of 1.94 - 2.45 eV and 2.04 � 2.51 eV respectively. The lowest energy gap was obtained from the polymer containing pyrrole unit due to the smallest resonance energy. These polymers also have very good thermal stability (onset decomposition temp, in N2 gases, >270 oC). The lower energy gap P(Pyrrole-SFPV) exhibited ten times better photoelectric power conversion efficiency than the higher energy gap P(TV-SFPV).
