Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. In an article, author is Xiao, Lixin, once mentioned the application of 709-63-7, Name is 4-(Trifluoromethyl)acetophenone, molecular formula is C9H7F3O. Now introduce a scientific discovery about this category, COA of Formula: https://www.ambeed.com/products/709-63-7.html.
A series of 1,8-naphthyridine derivatives is synthesized and their electron-transporting/injecting (ET/EI) properties are investigated via a multilayered electrophosphorescent organic light-emitting device (OLED) using fac-tris(2-phenylpyridine)iridium [Ir(ppy)3] as a green phosphorescent emitter doped into a 4,4-N,N-dicarbazolebiphenyl (CBP) host with 4,4-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (a-NPD) as the hole-transporting layer, and poly(arylene ether sulfone) containing tetraphenylbenzidine (TPDPES) doped with tris(4-bromophenyl)ammonium hexachloroantimonate (TBPAH) as the hole-injecting layer. The turn-on voltage of the device is 2.5 V using 2,7-bis[3-(2-phenyl)-1,8-naphthyridinyl]-9,9-dimethylfluorene (DNPF), lower than that of 3.0 V for the device using a conventional ET material. The maximum current efficiency (CE) and power efficiency (PE) of the DNPF device are much higher than those of a conventional device. With the aid of a hole-blocking (HB) and exciton-blocking layer of bathocuproine (BCP), 13.213.7% of the maximum external quantum efficiency (EQE) and a maximum PE of 50.254.5 lm W1 are obtained using the naphthyridine derivatives; these values are comparable with or even higher than the 13.6% for conventional ET material. The naphthyridine derivatives show high thermal stabilities, glass-transition temperatures much higher than that of aluminum(III) bis(2-methyl-8-quinolinato)-4-phenylphenolate (BAlq), and decomposition temperatures of 510518 degrees C, comparable to or even higher than those of Alq3.
These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. If you like, you can also browse other articles about this kind.
