Synthesis, morphology and optoelectronic properties of tris[(N-ethylcarbazolyl)(3′,5′-hexyloxybenzoyl)methane](phenanthroline)- europium

Abstract: The complex tris[1(N-ethylcarbazolyl)(3A,5A-hexyloxybenzoyl)methane](phenanthroline)europium 1 incorporates a phenanthroline ligand for electron transport and a carbazole fragment in the diketonate ligand for hole transport; furthermore, the six hexyloxy groups prevent crystallization and allow for the formation of transparent clear films directly from solution; the photoluminescence from films of 1 is nearly monochromatic, characteristic of the europium ion and proceeds with an efficiency of 50(3)%; light emi… Show more

“…To the best of our knowledge, this is the highest luminescence from single-layer devices based on pure Eu III complexes reported so far. [9,[12][13][14] Device C had a higher turn-on voltage of 10 V. Its maximum brightness of 21 cd m À2 was achieved at 17.8 V and 58.4 mA cm…”

“…Both of the four-layer devices based on pure 1 and 2 had a maximum brightness of more than 1000 cd m bazolyl, were introduced into the b-diketone ligand. [9] Furthermore, since the most popular neutral ligands, such as 1,10-phenanthroline (phen), triphenylphosphine oxide (TPPO) and 2,2'-bipyridine (bpy), also only exhibit very good electron-transport ability, [10,11] the hole-transporting triphenylamine and carbazole groups were introduced into phen or bpy derivatives to obtain a double-carrier transport ability. [12][13][14][15] Thus, the EL performance of these complexes was much improved.…”

“…These complexes have sharp as well as narrow emission, large Stoke's shifts, and long lifetime. These properties make them applicable for light emitting devices [1], electroluminescent materials [2], laser materials [3], luminescence probe [4], sensory materials [5] and full color light emitting display devices [6]. Out of three primary colors i.e red, blue and green, which is basic requirement for mechanized application of rare earth complexes, the terbium(III) ion metal complexes provide green color.…”

“…The synthesis of organic lanthanide complexes attract the attention of the researchers mainly owing to their captivating photophysical properties which found various applications such as luminescence materials [1], electroluminescence devices [2],], luminescent probes for development of fluoroimmuno-assays [3],organic light emitting devices (OLEDs) [4] and labels in biological system [5]. The emission of light originates from laporte forbidden intra-configurational 4f-4f transition of metal ion in the luminescent lanthanide complexes which lead to low intense absorption and emission spectra.…”
