摘要: Abstract The tunability of the electronic and optical properties thieno[3,4- b ]pyrazine-based terthienyls utilizing electron-donating electron-withdrawing side chains their corresponding polymers have been investigated. As previously shown for ]pyrazine monomers, addition groups results in higher HOMO–LUMO energies oligomers E g values resulting polymers. Correspondingly, use provides reduced lower values. effect is diminished comparison to analogs. However, application functionalized appears be a promising approach production low materials.
