Synthesis and properties of new light-emitting polymers containing fluorinated tetraphenyl units

A series of fully conjugated blue light-emitting polymers has been synthesized. The polymers are composed of fluorinated tetraphenyl units, and dialkoxybenzene, carbazole and fluorene containing arylenevinylene units. The synthesized polymers were soluble in common organic solvents and thermally stable up to 300 degrees C. The photoluminescence (PL) peak wavelengths of the polymers were varied from 490 to 468 nm, depending on the polymer structure. Single-layer EL devices using the polymers were fabricated. Light emission from the devices becomes visible between 12 and 22 V, depending on the device structure. (C) 2000 Elsevier Science S.A. All rights reserved.
