Synthesis and optical properties of novel conjugated polymer based on thiacalix[3]triazine and 3-hexylthiophene

Tóm tắt

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)
