摘要：

Copolymers of substituted phenylacetylenes containing the N,N-dimethylamino group have been produced with a rhodium catalyst, (bicyclo[2,2,1]hepta-2,5-diene)-rhodium(I)chloride dimer, from substituted phenylacetylenes (PA) monomers. These include 4-(N,N-dimethylamino)PA, PA, 4-chloroPA, 3-chloroPA and 4-nitroPA. The copolymers generally have 'better' properties in terms of solubility and molecular weight distribution than the corresponding homopolymer of 4-(N,N-dimethylamino)PA. Electron spin resonance. H-1 nuclear magnetic resonance, infrared and ultraviolet/visual spectroscopy, elemental analysis and gel permeation chromatography revealed that the structure of the copolymers resembles that of polyphenylacetylene. Doping with electron acceptors, such as iodine or chloranil, in solution, gives rise to bands in the optical absorption spectra near 700 nm, probably due to a cation involving the dimethylamine function. This indicates the possibility of doping a polyacetylene chain via a functional group on a substituent.
