Expanded benzofuran-decorated twistacene derivatives: synthesis, characterization and single-component white electroluminescence

Author affiliations

Abstract

Two novel phenanthro[9,10-b]benzofuran and pyreno[4,5-b]benzofuran modified twistacene derivatives, 9 and 10, have been successfully synthesized via Suzuki coupling and then characterized. The photophysical properties were examined and DFT calculations were carried out in a comparative manner, and both molecules emitted strong blue light in organic solvents and in the solid state. Impressively, fabricated electroluminescent devices based on these single emitters radiate pure white light.
