摘要：

Three vinylene-benzothiadiazole based alternating copolymers with carbazole, 3,6-difluoro carbazole and fluorene were prepared via Suzuki coupling polymerisation in the presence of catalytic amounts of palladium (II) acetate Pd(OAc)(2) and tri-ortho-tolylphosphine. P(o-tol)(3). The molecular weights measured by gel permeation chromatography and copolymers were characterised by NMR, UV-Vis spectroscopy and cyclic voltammetry. The physical properties and their band gaps are discussed in relation with their donor units (carbazole and fluorene derivatives).
