“…[1][2][3][4] Recently, we have reported that W-and Mo-based catalyst systems are very effective for the cyclopolymerization of dipropargyl derivatives (nonconjugated terminal diynes), giving conjugated double bonds in the polymer backbone and a cyclic recurring unit. [5][6][7][8][9][10][11][12][13][14][15] The corresponding polymers have good solubility in common organic solvents, long-term stability toward oxidation, and high electrical conductivity. In the cyclopolymerization of the nonconjugated diynes as well as the polymerization of substituted acetylenes by transitionmetal catalysts, the polymerization of ionic nonconjugated diynes has not been investigated so far because of its poor solubility in common organic solvents and the deactivating effect of polar ionic species on the Lewis-acidic transition-metal halide catalysts.…”

A new type of conjugated ionic polyacetylene was synthesized by metathesis polymerization of betaine monomers, alkyldipropargyl(4-sulfobutyl)ammonium betaines (ADPSAB). The alkyl groups used are ethyl, n-butyl, n-hexyl, and n-octyl. The polymerization of ADPSAB was carried out with various transition metal catalyst systems such as MoCl5-, WCl6-, and PdCl2-based catalyst systems. The MoCl5 and PdCl2 were found to be particularly effective catalysts for the cyclopolymerization of the betaine monomers. 1 H-NMR, 13 C-NMR, IR, and UV-visible spectroscopies showed that poly(ADPSAB) possess polyene structure having cyclic recurring units in the polymer backbone. Unlike polyelectrolyte, the resulting polymers were more soluble and showed higher viscosities in the salt solution than in salt-free solution (antipolyelectrolytes). When doped with an acceptor such as iodine, the polymers exhibited a substantial increase (∼10 -3 S/cm) in electrical conductivity compared to the undoped state (∼10 -10 S/cm).

A new class of multifunctional polymers based on poly(1, 6‐heptadiyne) derivatives with various functional groups such as carbazole unit for photoconductive polymers and nonlinear optical (NLO) chromophores for NLO polymers were synthesized by metathesis polymerization. The polymerizations were carried out with MoCl5‐ and WCl6‐based catalysts. The catalytic activity of MoCl5 was found to be greater than that of WCl6. The resulting polymers exhibited photoconductivity and large optical nonlinearity. These conjugated polymers have good solubility in common organic solvents, long‐term stability toward air oxidation, and high electrical conductivity.
