ABSTRACT Silicon-bridged fluorene copolymers bearing oligoarylenevinylene chromophore with longer effective conjugation length than terfluorene were prepared by the Suzuki coupling

copolymerization, where the polymer structure was designed so that the absorption spectrum of energy-accepting oligoarylenevinylene chromophore can overlap with the emission spectrum of

energy-donating terfluorene chromophore. The content of oligoarylenevinylene segment in 2A5, 2A10, 2A20, 2A48, and 2A100 could be well controlled by the monomer feed ratio as evidenced by

the UV spectra of copolymers in solution. Since the fluorescence from oligoarylenevinylene segment was observed in copolymers and the polymer blend system did not afford longer wavelength
