We have achieved a remarkable enhancement in current efficiencies and power efficiencies for red, green, and blue tandem phosphorescent organic LEDs (T-PhOLEDs) by employing LiF/Al/fullerene/zinc-phthalocyanine/MoO3 as a charge generation unit (CGU). Fullerene/zincphthalocyanine with a proper absorption property in the visible region can absorb a part of photons from emission layers within T-PhOLEDs, which facilitates the charge generation and separation within CGU.

Stable hosts with high triplet energy levels are of great importance for achieving highly efficient phosphorescence organic light-emitting diodes (PhOLEDs).

A thermally activated delayed fluorescence (TADF)-type exciplex host employing a novel electron-transport type (n-type) type host managing pos. polarons and stabilizing excitons was developed to elongate the device lifetime of deep blue phosphorescent organic light-emitting diodes (PhOLEDs). The bipolar n-type host was designed to prevent hole leakage and secure hole stability while being stabilized under excitons by introducing a CN-modified carbazole moiety as a weak donor. The TADF-type exciplex host-based blue PhOLEDs showed high (>20%) quantum efficiency with a deep blue color coordinate of (0.14, 0.16) and elongated device lifetime. The device operational lifetime of the blue PhOLEDs bearing the TADF-type exciplex host was extended by more than twice compared to that of the exciplex-free unipolar host. This work suggested a design concept of the n-type host to develop the TADF-type exciplex host for deep blue phosphors to reach a long lifespan in the deep blue PhOLEDs.

The high color rendering index (CRI) and doping-free four-emitting-layer (EML) white organic light-emitting diode (WOLED) with bipolar spacer layer was researched by different emitter sequence arrangements (pos. emitter sequence: B-G-O-R, reverse emitter sequence: R-O-G-B). The resulting four-emitting-layer WOLEDs with different sequences show opposite CRI trends when voltage increases, which includes the decreased trend in B-G-O-R sequence and increased trend in R-O-G-B sequence. That leads to WOLEDs with different sequences exhibit the highest CRI at obviously distinguishing luminance, which are CRI of 86 @ 531 cd m-2 in B-G-O-R sequence and CRI of 87 @ 13,340 cd m-2 in R-O-G-B sequence, resp. Meanwhile, the B-G-O-R and R-O-G-B sequences devices also exhibit a difference in the power efficiency. The different manifestations of CRI and efficiency characteristics are meticulously analyzed by a combined operation of energy transfer mechanism, carrier trap effect and the movement of carrier recombination zone in EML, resulting in a meaningful concept to design high CRI WOLEDs in different application scene.

The scaffolding of DNA (DNA) makes DNA mols. effective templates for hosting various types of nanomaterials. Recently, electrospun fibers formed by a variety of polymers have begun to see use in a number of applications, such as filtration in energy applications, insulation in thermodn. and protein scaffolding in biomedicine. In this study, we constructed electrospun fibers and thin films made of DNA and cetyltrimethylammonium chloride (CTMA)-modified DNA (CDNA) embedded with dyes, organic light-emitting materials (OLEMs), and gold nanorods (GNRs). These materials provide significant advantages, including selectivity of dimensionality, solubility in organic and inorganic solvents, and functionality enhancement. In addition, coaxial fibers made of CDNA were constructed to demonstrate the feasibility of constructing relatively complex fibers with an electrospinner. To determine the basic phys. characteristics of the fibers and thin films containing GNRs and OLEMs, we conducted current measurements, photoluminescence (PL) measurements, XPS, and UV-visible (UV-Vis) spectroscopy. The currents in DNA and CDNA were found to exhibit Ohmic behavior, while the PL emission could be controlled by OLEMs. In addition, the XPS provided the chem. configuration of samples, and the UV-Vis spectra revealed the plasmon resonance of GNR. Due to their simple fabrication and enhanced functionality, these DNA and CDNA fibers and thin films could be used in various devices (e.g., filters or blocking layers) and sensors (e.g., gas detectors and bio sensors) in a number of industries.

Organic light emitting diode has become a highly attractive technol. for high quality displays and lighting. These applications, however, strongly rely on their lifetime. Probing all the possible failure mechanisms has hence become crucial. We reveal here that the device lifespan depends on the dielec. strength, internal elec. field, morphol., thermal stability, and migration of the composing organic and inorganic materials as well as span of recombination zone and device efficiency. Addnl., the lifetime is highly sensitive to the thickness of electron transporting layer. By taking a green emitter doped in 4,4-bis(carbazol-9-yl)biphenyl host for example, the device lifetime can be increased from 51 to 209 h at 1000 cd/m2, an increment of 310%, and its efficacy increased from 21 to 41 lm/W, an increment of 96%, as the thickness is increased from 20 to 40 nm. The results show high device reliability to be achievable provided it composes materials with high dielec. strength, high glass transition property and low migration tendency, and uniform layered structure with low built-in internal elec. field, wide recombination zone and high efficiency.

Keywords: phosphorescent organic LED blue green red universal bipolar host; aggregation-induced emission; bipolar host; carrier transport; energy transfer; phosphorescent OLEDs. Let’s learn more about this compound (cas:435294-03-4).

Host materials are indispensable for the fabrication of organic light-emitting diodes (OLEDs) with phosphorescent emitters, but high-quality host materials that can efficiently and simultaneously function in blue, green, and red phosphorescent OLEDs (PHOLEDs) are much rare. Four bipolar materials are developed using carbazole and 9,9-dimethyl-9,10-dihydroacridine as hole-transporting groups, pyridine as electron-transporting groups, and biphenyl and m-methylbiphenyl as π-spacers. The crystal and electronic structures indicate that these materials have highly twisted conformations, which endow them with aggregation-induced emission features, intramol. charge transfer processes, wide energy band gaps, and high triplet energies. The carrier transport ability and energy transfer property analyses show that these materials are able to achieve balanced hole and electron transports and can serve as bipolar host materials for PHOLEDs. Monochromatic PHOLEDs with different phosphorescent dopants, including blue-emissive FIrpic, green-emissive Ir(ppy)2(acac), and red-emissive Ir(piq)2(acac), are fabricated by employing these 4 host materials. The green PHOLEDs can provide an impressive luminance of up to 230,200 cd m-2. Based on an identical host material, excellent external quantum efficiencies ≤25.12, 24.73, and 19.71%, as well as minor efficiency roll-off, are attained for blue, green, and red PHOLEDs, resp., clearly demonstrating the promising applications as universal bipolar host materials in PHOLEDs with monochromatic light and white light.
