A self-host thermally activated delayed fluorescence (TADF) dendrimer POCz-DPS for solution-processed nondoped blue organic light-emitting diodes (OLEDs) was designed and synthesized, in which the bipolar phosphine oxide carbazole moiety introduced by alkyl chain to ensure balanced charge transfer. The investigation of physical properties showed that dendrons not only improve morphological stability but also restrain concentration quenching effect TADF emissive core. spin-coated OLEDs...
A liquid/liquid interfacial reaction system was designed to fabricate α-Fe2O3 cubes. The uses a hydrophobic ionic liquid containing iron ions ([(C8H17)2(CH3)2N]FeCl4) for manufacturing cubes by novel and environmentally friendly hydrothermal method under low-temperature conditions (140 °C). iron-containing is can form interface with water, which vital fabrication of the Nanomaterials synthesized from liquids show good crystallinity, well-developed morphology, uniform size. effect different...
Due to the encapsulation of emissive core, concentration quenching effect TADF material can be effectively restrained.
Two soluble bipolar host materials (mCP-BPBI and CP-QPBI), comprising different proportions of hole-transporting carbazole electron-transporting benzimidazole, were synthesized. Their thermal, physical, electrochemical properties characterized. The designated bulky star-shaped structures efficiently suppress the direct intramolecular interaction between donor acceptor subunits to give high triplet energies. Through computational studies, varying ratio hole- moieties could significantly...
Abstract A series of nonionic surfactants, polyoxyethylene(n) monodehydroabietates (PEGylated DHAAs), were synthesized by an addition polymerization reaction between dehydroabietic acid (DHAA) and ethylene oxide (EO). The structures PEGylated DHAAs characterized FTIR, UV–vis 1 H NMR, their hydrophilic-lipophilic character surface activities evaluated water titration tension measurement, respectively. Meanwhile, the degree PEG chain in structure was determined according to results NMR...
Three solution-processable exciplex-type host materials were successfully designed and characterized by equal molar blending hole transporting molecules with a newly synthesized electron material, which possesses high thermal stability good film-forming ability through spin-coating technique. The excited-state dynamics the structure–property relationships systematically investigated. By gradually deepening highest occupied molecular orbital (HOMO) level of electron-donating components,...
To realize power efficient nondoped solution-processed OLEDs, a novel strategy of constructing TADF dendrimer with the characteristic exciplex-forming dendrons has been presented.
A benzimidazole/phosphine oxide hybrid 1,3,5-tris(1-(4-(diphenylphosphoryl)phenyl)-1H-benzo[d]imidazol-2-yl)benzene (TPOB) was newly designed and synthesized as the electron-transporting component to form an exciplex-type host with conventional hole-transporting material tris(4-carbazoyl-9-ylphenyl)amine (TCTA). Because of enhanced triplet energy electron affinity TPOB, leakage from exciplex-state constituting molecule eliminated. Using transfer exciplex-state, solution-processed blue...
Spatial separation of the TADF sensitizer and fluorescent emitter improve energy transfer efficiency by suppressing loss further enhance electroluminescent performance.
ABSTRACT A new highly selective photocatalyst (RhB‐MIP/TiO 2 ) was successfully prepared by surface molecular imprinting technique using rhodamine B (RhB) as template molecule. The adsorption kinetics show RhB‐MIP/TiO possessed fast rate, and behavior followed the pseudo‐second‐order kinetics. static binding experiments revealed displayed strong affinity high capacity for RhB. Moreover, equilibrium rate of RhB can be well fitted Langmuir isotherm model. thermodynamics parameters indicated...
