SYNTHESIS AND OPTICAL PROPERTIES OF NOVEL CONJUGATED POLYMER BASED ON THIACALIX[3]TRIAZINE AND 3-HEXYLTHIOPHENE
Main Article Content
Abstract
In this study, we synthesized the novel conjugated polymers based on thiacaliax[3]triazine and 3-hexylthiophene via C-H direct arylation polymerization. The chemical structure of obtained conjugated polymers has a donor – acceptor moieties including thiacaliax[3]triazine as acceptor units due to electron withdrawing properties of triazine and donor moieties such as 3-hexylthiophene. The structure of the resulted polymer was characterized via FTIR and 1H NMR spectrum. In addition, the molecular weight of the polymer was determined by GPC analysis. The optical properties of the polymer were investigated via UV-Vis and PL spectrometer. The novel conjugated polymers have been expected to have a narrow band-gap and redshift absorption and could be applied for organic solar cells (OSCs)
