Summary
Novel conjugated polymers based on fluorene having 1-(2-benzothiazolyl)-3, 5-diphenylpyrazoline unit in the main chain were synthesized in good yields through Suzuki coupling reactions. All polymers were quite soluble in a variety of organic solvents. Transparent and uniform thin films of the polymers were obtained easily by casting or spin-coating from toluene solution. These polymers possessed satisfactory thermal stability. The polymers exhibited strong bluish-green photoluminescence in solution and green photoluminescence in the solid state.
