Koohmareh, Gholam Ali published the artcileSynthesis, characterization, and optical properties of new pyridine- and thiophene-based copolymer bearing bulky naphthyl group, Synthetic Route of 239075-02-6, the publication is Polymer Bulletin (Heidelberg, Germany) (2015), 72(11), 2979-2990, database is CAplus.
A new copolymer was synthesized via reaction of new pyridine-containing dibromo compound, 2,6-bis(4-bromophenyl)-4-(naphthalen-1-yl) pyridine, with thiophene-based diboronic ester via Suzuki cross-coupling reactions. 2,6-Bis(4-bromophenyl)-4-(naphthalen-1-yl) pyridine was synthesized starting from condensation reactions of 4-bromoacetophenone and 1-naphthaldehyde. The synthesized monomer and polymer were characterized by FT-IR and NMR spectroscopy. The phys. properties of the polymer, including solubility and viscosity were studied, and the results showed good solubility and chain growth for polymer. Maximum absorption peak for polymer was 388 nm. The optical band gap energy of the polymers was determined by absorption onset and 2.38 eV for polymer.
