Two novel polythiophenes with 1,3-dioxane group in the side chain named poly[3-(1,3-dioxane-2-ylethyl)thiophene] (PDT) and poly[3-(1,3-dioxane-2-ylethyl)-4-methyl- thiophene] (PDMT) were synthesized via oxidative polymerization firstly to form their precursor polymers and substitution secondly to obtain the target polymers in this paper. The chemical structures, molecular weights, thermal properties of the polymers were characterized by 1H NMR, FT-IR, GPC, and TGA respectively, indicating that both polymers had high molecular weight and good thermal stability. Meanwhile, the optical absorption and photoluminescence (PL) of both polymers were investigated and the results showed that the maximum absorption and emission wavelengths of PDMT were blue-shifted than that of PDT due to its methyl-substitution at 4-position in thiophene.
