- Abstract
- A new series of alternating copolymers composed of 1,4-phenylenevinylene and 2,5-thienylenylvinylene repeating units with various side chain substituents were synthesized via the Heck coupling reaction for use in light-emitting diodes (LEDs). The resulting copolymers were characterized using H-1- and C-13-NMR, DSC, and TGA. These polymers were found to be soluble in common organic solvents and are easily spin-coated onto glass substrates, producing high optical quality thin films without defects. The electro-optical properties of ITO/PEDOT/Polymer/Al devices were investigated using UV-VIS, PL and EL spectroscopy. The turn-on voltages of these devices were found to be in the range 4-16 V, with a maximum brightness of about 2900 cd/m(2) at 12 V. (C) 2004 Elsevier Ltd. All rights reserved.
