Dibenzo[a,d]cycloheptenyl dibenzophosphole palladium dichloride: Synthesis, X-ray-crystal structure and application in the Suzuki-Miyaura coupling

A highly rigid dibenzo[a,d]cycloheptenyl dibenzophosphole with a pre-organized concave shaped binding site acts as an efficient ligand in the palladium catalyzed Suzuki-Miyaura coupling process between halogenoaromatics and phenylboronic acid. The Royal Society of Chemistry 2005.

Phosphafluorenyl lithiums: direct synthesis from white phosphorus, structure and diversified synthons

While rich chemistry of phospholyl anions is discovered, phosphafluorenyl anions are only proposed as the critical intermediates for the synthesis of phosphafluorenes. In this article, we reported the direct synthesis of phosphafluorenyl lithiums from white phosphorus (P4) through direct P–C bond formation. The reaction between P4 and biphenyl dilithio reagents efficiently afforded phosphafluorenyl lithiums, which were further used to synthesize different kinds of organophosphorus compounds. The aggregation states of phosphafluorenyl lithiums were investigated for the first time. Mechanistic studies by DFT calculations revealed a cooperative nucleophilic attack of two C?Li bonds on P4 molecule.[Figure not available: see fulltext.]

Phosphorescent OLEDs assembled using Os(ii) phosphors and a bipolar host material consisting of both carbazole and dibenzophosphole oxide

We report on the synthesis of a new series of Os(ii) complexes (1-3) functionalized with 2-pyridyl (or 2-isoquinolyl) pyrazole chelates, together with a new diphosphine, 1,2-bis(phospholano)benzene chelate (pp2b). The resulting Os(ii) complexes are fully characterized and their structural versus spectroscopic properties have been comprehended by absorption/emission together with computational approaches. The inherent electron richness, restricted rotational barrier and good steric hindrance of pp2b lead to the production of both orange and red phosphorescence with high quantum efficiency. For exploring these Os(ii) based OLEDs, we also synthesized a bipolar material 5-[4-(carbazo-9-yl)phenyl] dibenzophosphole-5-oxide (CzPhO), possessing both carbazole donor and dibenzophosphole oxide acceptor. Successful fabrication of OLEDs using complexes 1 and 3 as the dopant and either 4,4′-N,N′- dicarbazolebiphenyl (CBP) or CzPhO as host is reported. For comparison, the CBP and CzPhO devices with 1 as the emitter showed peak efficiencies EQE of 10.9%, ηL of 21.7 cd A-1, and ηp of 11.9 lm W-1, and EQE of 14.3%, ηL of 34.8 cd A-1, and ηp of 45.2 lm W-1, respectively.
