Paper Title:
Synthesis and Optical Properties of an Alternating Conjugated Copolymer Composed of 2,5-Divinyl-3,4-Dialkylthiophene and 2,6-Pyridine
  Abstract

An alternating conjugated copolymer composed of 2,5-divinyl-3,4-dialkylthiophene and 2,6-pyridine was synthesized by Heck coupling approach. The regioregular poly(3, 4-dialkylthiophene) was prepared by McCullough for the comparing research. The obtained polymers were evaluated with 1H NMR, FT-IR, gel permeation chromatography (GPC), thermo-gravimetric analysis (TGA), UV–vis spectroscopy, and photoluminescence (PL). The results indicate that the polymers depict outstanding thermal stabilities, low band gaps, and high PL quantum efficiency, and they might be excellent polymeric materials for applications in organic light-emitting diodes (OLEDs), light-emitting electrochemical cells, polymer solar cells, and so on.
