Abstract
Recent results are reported on the synthesis of statistical copolymers 8 and 9 derived from the highly luminescent silyl PPV derivative (DMOS-PPV) with various alternative building blocks carrying side chains capable of supporting polyelectrolytes. These polymers are prepared by Gilch dehydrohalogenation polymerization. It is of interest to study the effect on charge transport in standard electroluminescent (EL) devices using these PPV copolymers. Moderately efficient conventional single-layer devices are obtained for copolymer 9. When fabricated in a light-emitting electrochemical cell (LEC) configuration (lithium triflate) without any extra supporting polymer electrolyte (e.g., poly(ethylene oxide), PEO), devices based on both 8 and 9 show lower turn-on voltages and improved efficiency.
