A series of novel substituted acetylene monomers bearing fluorene pendant groups (C13H9COCH2CH2CO-R-CH2CCH, R=NH (IV1), R=O (IV2), R=NHCH(CH3)CONH (IV3), R=NHCH(CH3)COO (IV4)) have been synthesized and subsequently polymerized with [Rh(nbd)Cl]2 as a catalyst to obtain the corresponding polyacetylenes (Poly(IV1–4)). The 1H NMR spectra demonstrated that all the obtained polyacetylenes had high cis-stereoregular...
