Among the various conjugated polymers obtained from acetylenic monomers, poly(1,6-heptadiyne) and its homologues are the powerful candidate of π-conjugated backbone material because these polymers can improve the solubility and oxidative stability of acetylenic polymers by the introduction of functional substitutents at 4-position of 1,6-heptadiyne. Here, we report the synthesis of a novel class of polyacetylene with two cyclic recurring unit via the double ring-forming cyclopolymerization of a triyne monomer, 4,10-bis(diethyl malonate)-1,6,11-dodecatriyne. The chemical structure of resulting polymer was characterized by NMR, IR, and UV-visible spectroscopies to have a conjugated backbone system. From the CV measurements, the HOMO energy level of the polymer was calculated to be 5.55 eV. This polymer showed characteristic wide UV-visible absorption band and PL maximum peak at 530 nm corresponding to the photon energy of 2.34 eV. |
