Blue OLED materials applied to color mobile phone market and took growing public interests but display panel manufacturer still cannot be satisfied with the current blue performance as a high performance color display panel and highly efficient blue emitting materials are the remaining subjects to be solved. In this work we synthesized a new deep-blue and sky-blue emitting material using fluoranthene moieties such as 7,8,10-triphenylfluoranthene[TPF] and 7,12-diphenylbenzo[k]fluoranthene[DPBF]. The TPF and DPBF thin films exhibited maximum UV-visible absorption at 382 and 415 nm, respectively. The PL emission peaks of TPF and DPBF were found to be 456 and 453nm. EL devices were fabricated with synthesized material and evaluated in terms of emission color and luminescence efficiency. |
