The acidic methyl protons in 2-decyloxy-4,6-dimethylpyrimidine can be easily deprotonated using a base, because the resultant carbanion is resonance stabilized. This stable carbanion can be used as a substrate for aldol condensation reactions. A series of novel conjugated polymers were synthesized using aldol condensation reactions between 2-decyloxy-4,6-dimethylpyrimidine and various aromatic dialdehydes. The synthesized polymers were characterized by using 1H-NMR, UV-visible spectroscopy. Molecular weights of the polymers were determined by size exclusion chromatography. Cyclic voltammetry was used to determine HOMO, LUMO energy levels and electrochemical band gaps of the resultant polymers.
