Usage

Applications

1,3-Bis(N-carbazolyl)benzene, known as mCP, with a high triplet energy (ET = 2.91 eV) and a very deep highest occupied molecular orbital (HOMO) level, is often used as host materials for efficient blue phosphorescent light-emitting diodes. Kawamura et al. demonstrated that the photoluminescence internal quantum yield of the blue emitter of FIrpic could approach nearly 100% when doped into the wide energy gap host of mCP.

Preparation method of 1,3-dicarbazolyl benzene

The invention provides a preparation method of 1,3-dicarbazolyl benzene, which is characterized in that 1,3-dichlorobenzene and carbazole are effectively coupled to generate 1,3-dicarbazolyl benzene (mCP) under the action of a tri(aryl phosphine) coordinated palladium catalyst and an organic magnesium reagent. The method is characterized in that a tri(aryl phosphine) having the general formula Ia,Ib or mixtures thereof is used as a supporting ligand for the palladium catalyst.

Mixed er-NHC/phosphine Pd(ii) complexes and their catalytic activity in the Buchwald-Hartwig reaction under solvent-free conditions

A series of novel (NHC)PdCl2-PR3 complexes were synthesized and fully characterized by 1H, 13C, 31P NMR and FT-IR spectroscopy. These complexes showed high catalytic activity toward solvent-free Buchwald-Hartwig amination. Both primary and secondary amines were efficiently utilized under the same reaction conditions. The solvent-free synthesis of valuable N-aryl carbazoles and similar N-heterocyclic systems was described.

Solution-processable highly efficient deep-red and orange organic light-emitting diodes based on multi-functional Ir(III) complexes

A heteroleptic deep-red iridium(iii) complex, TPQIr-HT, based on thiophene-phenylquinoline (TPQ), and orange Ir(iii) complexes, m-CF3DPQIr-HT and m-CF3DPQIr-ET based on diphenylquinoline (DPQ), are designed by attaching a carbazole-based hole transporting (HT) group and an oxadiazole (OXD)-based electron transporting (ET) group to the parent Ir(iii) complexes, TPQIr and m-CF3DPQIr. The Ir(iii) complexes TPQIr-HT show a deep-red emission peak at 612 nm, similar to that of TPQIr, whereas m-CF3DPQIr-HT and m-CF3DPQIr-ET show an orange emission peak at 567 ± 1 nm, which is similar to that of m-CF3DPQIr. The newly functionalized Ir(iii) complexes show improved device performance compared to the Ir(iii) complexes, TPQIr and m-CF3DPQIr, without the additional functional groups. The phosphorescent organic light-emitting diodes (PhOLEDs) fabricated using a deep-red Ir(iii) complex, TPQIr-ET, achieved a maximum external quantum efficiency (EQE) of 17.47% using GraHIL as the hole injection layer (HIL). Similarly, the orange Ir(iii) complex, m-CF3DPQIr-HT, achieved a maximum EQE of 21.61%.
