Abstract
In this paper, a new UV-violet emission type material 9'-((9,9-dibutyl-9H-fluorene-2,7-diyl)bis(4,1-phenylene)) bis(9H-carbazole) (DBF-2PC) was synthesized by incorporating carbazole groups and fluorine into one molecule. The steric and bulky compound DBP-2PC exhibits good thermal stabilities with high glass transition temperatures (117 °C) and good thermal stability (403 °C at 5% weight loss). The fluorescence emission of as-prepared DBP-2PC compounds results in the UV to blue-violet region of 397 nm with narrow full width half maximum (FWHM) of 44 nm in solution. Light-emitting device is successfully fabricated using the material as emitter, and emit UV to blue-violet light.
