Simple solution processable carbazole-oxadiazole hybrids for un-doped deep-blue OLEDs
Journal of Photochemistry and Photobiology A: Chemistry(2018)
Abstract
•Synthesized and characterized two novel carbazole-oxadiazole based D-π-A hybrids.•These hybrids exhibited favorable photophysical, and thin film forming properties.•Showed blue emission in solution and thin film states with excellent color purity.•OLEDs based on these hybrids exhibited blue electroluminescence with a narrow FWHM.•The luminance and current efficacy demonstrate the use of these hybrids in OLEDs.
