Abstract
Stille cross-coupling reactions of 2,6-bis(tributylstannyl)-4,4-bis(4-butylphenyl)dithienosilole with dihaloarenes gave dithienosilole-arene alternate polymers. The resulting copolymers showed the UV absorption and emission maxima at 450-601 nm and 543-698 nm, respectively, depending on the arene units in the polymer backbone. Electroluminescence properties of the dithienosilole-pyridine polymer were studied in its spin-coated film.
