Novel synthesis of polyelectrolyte : the synthesis of poly(dihexyldipropargyl ammonium) salts by transition metal catalysts새로운 고분자 전해질의 합성 : 전이금속 촉매에 의한 폴리디헥실디프로파길 암

A new type of conjugated ionic polyacetylene was synthesized by metathesis polymerization with transition metal catalyst. The monomers used were dihexyldipropargyl ammonium salts having bromide and tosylate as counteranions. It was found that $MoCl_5$-based catalyst systems were very effective for the cyclopolymerization of the present ionic monomers. $^1H$,$^{13}C$ NMR, IR, UV-visible spectroscopies showed that these polymers possess polyene structures having 6-membered cyclic recurring units in the polymer backbone. The polymers obtained exhibit good solubility in polar organic solvents such as methanol, DMSO, DMF, THF, $CHCL_3$, etc., indicative of their ionic nature. When doped with an acceptor such as iodine, the polymers exhibited a substantial increase ($\sim$10$^{-3}$S/cm) in electrical conductivity compared to the undoped state ($\sim$10$^{-9}$S/cm).
