2-Phenyl-5-(p-tolyl)-1,3,4-oxadiazole
The title compound, C(15)H(12)N(2)O, adopts the expected near-planar geometry, the phenyl and tolyl rings being inclined relative to the oxadiazole ring by 3.8 (3) and 8.3 (2)°, respectively. This allows adjacent mol-ecules to pack in a parallel fashion and form stacking along [010] via π-π inter-actions [centroid-centroid distances = 3.629 (2) and 3.723 (2) Å]. Further inter-molecular inter-ac...
متن کاملDegradation mechanism of phosphorescent-dye-doped polymer light-emitting diodes
The degradation mechanism of phosphorescent-dye-doped polymer light-emitting diodes ~PLEDs! is investigated. The active medium of our PLED is a polymer blend comprising poly~vinylcarbazole! ~PVK!, @2-~4-biphenylyl!-5-~4-tert-butyl-phenyl!-1,3,4-oxadiazole# ~t-PBD!, and platinum~II!-2,8,12,17-tetraethyl-3,7,13,18-tetramethylporphyrin ~PtOX!. The cyclic voltammetry result shows that the reductive...

In the title compound, C(28)H(28)N(4)O(4)S, the dihedral angles between the central thio-phene ring and its pendant oxadiazole rings are 1.2 (3) and 9.8 (3)°. The dihedral angles between the oxadiazole and phenyl rings are 2.9 (3) and 1.8 (3)°. Some short intra-molecular C-H⋯O contacts occur.
متن کاملRed Phosphorescent Organic Light-Emitting Diodes Using Mixture System of Small-Molecule and Polymer Host
We study two types of polymer materials, poly(n-vinylcarbazole) (PVK) and starburst small-molecule 1,3,5-tris[4(diphenylamino)phenyl]benzene (TDAPB), as the host for electrophosphorescent organic light-emitting diodes (PHOLEDs) doped with red-emitting phosphor tris(1-phenylisoquinoline) iridium (III) [Ir(piq)3]. PHOLEDs employed a PVK and TDAPB blend as the host exhibited a maximum red light em...
متن کاملBromidotricarbonyl[2-phenyl-5-(pyridin-2-yl-κN)-1,3,4-oxadiazole-κN 4]rhenium(I) dichloromethane monosolvate
In the title rhenium(I) complex, [ReBr(C(13)H(9)N(3)O)(CO)(3)]·CH(2)Cl(2), the dichloro-methane solvent mol-ecule is disordered over two positions with an occupancy ratio of 0.81 (15):0.19 (15). The Re(I) atom is coordinated by two N atoms from a 2-phenyl-5-(pyridin-2-yl-κN)-1,3,4-oxadiazole (L) ligand, three C atoms from three carbonyl groups and a Br atom in a distorted octa-hedral geometry. ...
