Cyclopolymerization of α-methylbenzyl dipropargylamine by transition metal catalysts

Synthesis and properties of poly(N-benzoyl-2-ethynylpyridinium chloride)

“…However, despite a high conductivity, its instability in atmospheric conditions constitutes a major obstacle to practical applications. On the other hand, the substituted polyacetylenes have exhibited improved solubility, leading to processibility, and improved stability but with considerable sacrifice of electrical properties [10,[17][18][19][20][21][22]. The attachment of pendant groups can also add the designed functional properties to polyacetylene.…”

“…The attachment of pendant groups can also add the designed functional properties to polyacetylene. Various substituted polyacetylenes have been prepared by the linear polymerization of the corresponding acetylene monomers [1,[18][19][20][21][22]. Especially, 2-ethynylpyridine was thermally polymerized to give a low yield of polymer with low molecular weight [23].…”

Electro-optical and electrochemical properties of an conjugated cyclopolymer: Poly(9,9-dipropargylfluorene)

“…Because of these properties, polyacetylene and its homologues have been promising as organic semiconductors, as membranes for gas separation and for liquid-mixture separation, as chirooptical materials, as side-chain liquid crystals, as materials for chemical sensors, and as materials for nonlinear optical property and for photoluminescence and electroluminescence properties [8][9][10][11][12][13][14][15].…”

Synthesis of conjugated spirocyclic polymers: Cyclopolymerization of 1,1-dipropargyl-1-silacycloalkanes by transition metal catalysts

“…More manageable conjugated polymers have been prepared by the introduction of functional substituents into the polyacetylene. The substituents caused important changes in the properties of polymer, such as solubility, stability, melting, chemical, optical, electrical, and other properties [1,2,[9][10][11][12][13][14][15][16].…”
