wo new copolymers, P1 and P2, composed of 4[4-(alkoxy)phenyl]-2, 6-bis(4-bromophenyl)pyridine and bithiophene units, have been synthesized via Suzuki cross-coupling reactions. 4[4-(alkoxy)phenyl]-2, 6-bis(4-bromophenyl)pyridines were synthesized starting from condensation reaction of 4-bromoacetophenone and 4-hydroxy benzaldehyde, and subsequent alkoxylation of hydroxyl groups. All of the polymers and intermediates were characterized using FTIR and NMR spectroscopies. The synthesized polymers exhibit good solubility in common organic solvents. The maximum absorption peak for P1 and P2 was 430 and 420 nm, respectively. The optical band gap energy of the polymers was determined by absorption onset and found to be 2.17 eV for P1 and 2.13 eV for P2. © 2013 Taylor & Francis.
