Kay, Kwang-Yol published the artcileSynthesis and electroluminescent properties of fluorene- and anthracene-derivatives containing novel tetraphenylbenzene moiety, COA of Formula: C18H10, the publication is Molecular Crystals and Liquid Crystals (2004), 167-172, database is CAplus.
2,7-Bis[(2,3,4,5-tetraphenyl)phenyl]-9,9-diethylfluorene (BTPDF) and 2,7-bis[(2,3,4,5-tetraphenyl)phenyl]-9,10-anthracene (BTPA), which consist of a diethylfluorene and an anthracene with two tetraphenylbenzene moieties, were synthesized by Diels-Alder reaction and characterized to investigate electroluminescent (EL) behavior. BTPDF and BTPA showed violet and blue photoluminescence spectra at 400 nm and 456 nm. The device of m-MTDATA (600 脜)/NPB (150 脜)/BTPDF or BTPA (300 脜)/Alq3 (300 脜)/LiF (10 脜)/Al (2000 脜) showed turn-on voltage of 9 V and 13 V and blue and green EL spectrum at 466 nm and 504 nm, resp.
