Hole transporting layer plays a crucial role to realize high efficiency and long lifespan by balancing the charge carrier into desired recombination zone.
Micro-light-emitting diodes (μLEDs) are getting much attention in display industry because of their outstanding optical and electrical characteristics. μLEDs have several advantages over liquid crystal displays (LCDs) organic light-emitting (OLEDs). showing long lifetimes, high reliability, power efficiencies, brightness, fast response times with tiny pixels. However, for commercial usage, the production cost low external quantum efficiency (EQE) major hurdles. In this review, we briefly...
Wet-process enables organic light-emitting diodes (OLEDs) to be made cost-effectively <italic>via</italic> a continuous process, such as roll-to-roll manufacturing.
Two bipolar non-conjugated deep-blue emitters, PICFOCz and BICFOCz, were synthesized by incorporating the charge transporting carbazole (donor/hole transporting) imidazole (acceptor/electron moieties <italic>via</italic> a flexible alkyl spacer.
Five new, star-shaped compounds containing a central oligo(phenylenevinylene) core carrying six alkoxy chains were synthesized, and with varying alkyl the changes in their supramolecular assembly explored by small wide-angle X-ray scattering (SAXS/WAXS) studies. For shortest peripheral chain (3.1; R = 3,7-dimethyl octyl) lamellar stacking was favored, whereas increasing length (3.2, 3.3, 3.4, 3.5; n-C12H25, n-C14H29, n-C16H33, n-C18H35) columnar rectangular (Colr) observed. The compound...
We report several molecules based on a central pyrazino[2,3-g]quinoxaline unit which is substituted with eight peripheral flexible tails of varying length. The out-of-plane conformation the phenyl moieties made self-assembly very sensitive to minute variation in molecular structure. compounds short and branched chains did not stabilize any liquid crystalline phase, while medium- long-chain homologues exhibited columnar phases. All high extinction coefficient good greenish-yellow emission...
We present a strategy for developing an in-depth understanding of the synergy between triplet energy (ET) and structural composition molecular hosts organic light-emitting diodes (OLEDs) initially through virtual screening molecules with help density functional theory (DFT) followed by experimental validation. Four solution-processable belonging to two groups positional isomers based on similar constitutional core have been theoretically screened employed in OLED devices. Remarkably,...
Well-defined electroactive bipolar derivatives of new structure have been synthesized from 3-(N,N-diphenylamino)-9H-carbazole and bis(4-fluorophenyl)sulfone, 4-fluorophenylsulfone or 4,4′-difluorobenzophenone, respectively. The full characterization their is described. amorphous materials with very high glass transition temperatures 111–173 °C also possess thermal stability, onset decomposition 351–398 °C. Some the compounds having best solubility were tested as emitters dispersed in...
Nano structures enable organic light-emitting diode (OLED) devices to be fabricated with relatively high efficiency and brightness, opening up a new era for quality displays lighting, wherein devising pseudo-natural light is always must. The uses of incandescent bulbs are the most friendly, electricity-driven lighting sources, measure from perspectives human eye protection, melatonin generation, artifacts, ecosystems, environment, night skies due their intrinsically low blue emission....
Surface roughness of electrodes plays a key role in the dielectric breakdown thin-film organic devices. The rate will increase when there are stochastic sharp spikes on surface electrodes. Additionally, having spiking morphology makes determination strength very challenging, specifically layer is relatively thin. We demonstrate here new approach to investigate thin films for light-emitting diodes (OLEDs). were deposited substrate using physical vapor deposition (PVD) under high vacuum....
Pyridinyl-carbazole fragments containing low molar mass compounds as host derivatives H1 and H2 were synthesized, investigated, used for the preparation of electro-phosphorescent organic light-emitting devices (PhOLEDs). The materials demonstrated high stability against thermal decomposition with temperatures 361–386 °C suitable thin amorphous homogeneous layers very values glass transition 127–139 °C. It was determined that triplet energy are, correspondingly, 2.82 eV derivative 2.81 H2....
