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 PL spectra at 400 nm and 456 nm. The device of m-MTDATA(600Angstrom)/NPB(150Angstrom)/BTPDF or BTPA(300Angstrom)/ Alq(3)(300Angstrom)/LiF(10Angstrom)/Al(2000Angstrom) showed turn-on voltage of 9 V and 13V and blue and green EL spectrum at 466 nm and 504 nm, respectively.
