Stable hosts with high triplet energy levels are of great importance for achieving highly efficient phosphorescence organic light-emitting diodes (PhOLEDs). In this work, a simple and robust spirobifluorene derivative peripherally substituted with tetrakisarylsilyls was designed and synthesized. The spirobifluorene derivative exhibits high thermal/morphol. stabilities and ultra-violet blue emissions with moderate fluorescence quantum yields. DFT calculation indicates that the frontier MOs (FMOs) are mainly associated with the spirobifluorene segment and there is very limited distribution on the peripheral substituents. PhOLEDs using TPSiF as a universal host were fabricated and blue to red emissions were achieved with high efficiencies, among which the green device using Ir(ppy)2acac as guest showed high performance with maximum luminance, current efficiency, power efficiency and external quantum efficiency (EQE) of 11690 cd m-2, 77.2 cd A-1, 47.3 lm W-1, and 21.1%, resp.

The paper describes the preparation and characterization methodol. of thermal neutron sensitive inorganic compound loaded polystyrene based thin-film Plastic Scintillators (PS). Inorganic compounds with thermal neutron sensitive elements such as B2O3, LiF, Gd2O2S:Tb, Gd2O3, Gd(BO2)3:Tb is loaded in plastic scintillators, at predetermined weight percentage in a solvent-based fabrication method. The PS base solution is prepared by dissolving required quantities of polystyrene, 2,5-Diphenyloxazole (PPO), 1,4-bis(5-Phenyloxazol-2-yl) Benzene (POPOP) in the p-xylene solvent. The loading material is mixed with the scintillator solution and coated over cellulose acetate-based transparency sheet. Thin sheets of 200 x 150 mm size and 250 ± 50 μm thickness PS are prepared through multiple coating. Photoluminescence (PL), Radioluminescence (RL) and pulse height spectra (PHS) of α, β, γ and neutron sources of the composite scintillators are studied. The selection of loading compounds is decided on their phys. properties such as refractive index, the at. percentage of neutron sensitive elements in the inorganic compound, band gap, and cost and availability of material. Gadolinium based compounds as a thermal neutron absorber showed higher detection capability for low-energy neutrons. Among the gadolinium loaded PS, Gd(BO2)3:Tb (14.3 wt%) composite scintillator showed the highest RL. A comprehensive anal. of PL, RL, PHS of α, pure β and γ sources, un-moderated and moderated Am-Be neutron source is discussed in the paper.

The capture and conversion of H2S is of importance towards long-standing economic and environmental challenge. Hence, a series of task-specific ionic liquids were developed and presented as both absorbents and catalysts for simultaneous capture and conversion of H2S into high valuable mercaptan acids using unsaturated acids as starting materials. Good to quant. conversion was realized with catalytic loading of ILs. Water extraction was employed to sep. the product from the reaction system. The kinetic isotherm demonstrated that the addition reaction can achieve 98% conversion at 90°C and 50 mol% of catalyst loading within 1 h. A plausible reaction-separation-integration strategy was further proposed. This work discloses a green, simple, and mild but effective method for the capture and catalytic conversion of H2S into high valuable mercaptan acids.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Triplet Exciton Upconverting Blue Exciplex Host for Deep Blue Phosphors, published in 2021-09-01, which mentions a compound: 435294-03-4, Name is Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III), Molecular C35H27N2O2Ir, Reference of Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III).

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.

Color-tunable white organic light-emitting diodes (CT-WOLEDs) having daylight chromaticity and a wide correlated color temperature (CCT) span can mimic our circadian cycle and realize application for lighting or decoration. The effects of the recombination zone and energy distribution on the electro-optical properties and color span are investigated in this paper. We find that it is beneficial to expand the CCT span by increasing the distance between the red ultrathin phosphorescent emissive layer and the center of the recombination zone. By increasing the concentration (y) of mCP in mixed host material in the emitting layer and the thickness (z nm) of the red ultrathin phosphorescent emissive layer, the CCT spans can be expanded towards high CCT and low CCT, resp. The widest CCT span reaches 4032 K (2391-6423 K) in a simple all-phosphorescent CT-WOLED with a maximum luminance and power efficiency of 9249 cd m-2 and 15.35 lm W-1, resp.
