ASPECTS OF SYNTHESIS, ANALYSIS AND APPLICATION OF AROMATIC CONJUGATED POLYMERS

A wide variety of soluble and fusible derivatives of poly(1,4-phenylenevinylene) were prepared by the Pd-catalysed arylation of ethylene with dihalogenoarenes. Although thermogravimetry indicates good thermal stability of most of the fusible derivatives of poly(1,4-phenylenevinylene), irreversible changes combined with a loss of anisotropy, solidification and insolubility occurred in the molten state on annealing. Soluble and fusible poly(phenyl-1,4-phenylene) was prepared by a Ni-catalysed Grignard reaction and by a precursor route.
