Among them,
direct C-H coupling reaction gave the polymer with the highest molecular
weight. The resulting polymer was soluble in common organic solvents.
Absorption and fluorescence spectra of the polymer showed a remarkable
red-shift compared with the corresponding monomer due to the expansion of
effective ¦Ð-conjugation length.</span>
