This article reviews the chemistry of substituted polyacetylenes developed by our research
group, more specifically, development of polymerization catalyst, synthesis of new polymers …

Rigid polymer backbones have often been considered to be detrimental to the packing of
mesogenic pendants, and polyacetylenes have generally been regarded as unpromising …

Poly (1, 6-heptadiyne)-based polyacetylenes as a new class of π-conjugated polymer were
designed and prepared. In general, the Mo-based catalysts were found to be very effective …

Cyclic polyacetylene (c-PA) is the cyclic derivative of the semiconducting linear
polyacetylene. As with the linear derivative, cyclic polyacetylene is insoluble, making its …

For many years, considerable research efforts have been dedicated to π‐conjugated
polymers because of their extraordinary electronic, optical, and structural properties. The …

A group of mesomorphic polyacetylenes with different lengths of alkyl spacer−{HC C [(CH 2)
m− OCO− Biph− OC7H15]} n−[1 (m), m= 2, 3, 4, 9] and orientations of ester bridge−{HC C …

Complex [tBuOCO] WC (tBu)(THF) 2 (1){where tBuOCO=[2, 6-(tBuC6H3O) 2C6H3] 3−, THF=
tetrahydrofuran} polymerizes acetylenes (R-phenylacetylene (R= H, p-OMe, pF, 3, 5-diCF3) …

Abstract Poly‐(2‐ethynylpyridinum bromide)(PEPBP) having propargyl side chains was
prepared by the direct polymerization of 2‐ethynylpyridine and propargyl bromide under …

Diphenylacetylenes containing chiral menthyl groups [C6H5C C− C6H4OCOCH2OR* and
C6H5C C− C6H4CO2R*, R*=(1 R, 2 S, 5 R)-(−)-menthyl] are synthesized and polymerized …

Biphenyl-(Biph-) containing 1-alkynes (3 and 4) and their polymers (1 and 2) with varying
bridge groups and spacer lengths were synthesized and the effects of the structural variation …
