✦ Synopsis

A variety of long alkyl acetylenic compounds was synthesized and polymerized by using Rh(I) catalysts. Particularly, the monomer having a terminal hydroxyl group was converted into the high molecular weight of polymer in good conversion, which was soluble in THF, DMSO, and DMF. The high stereoregularity (cis) in the main chain was confirmed by 1 H-NMR in DMSO-d 6 and the rod-like structure by wide-angle X-ray diffraction.
