Reference of 13991-08-7, An article , which mentions 13991-08-7, molecular formula is C30H24P2. The compound – 1,2-Bis(diphenylphosphino)benzene played an important role in people’s production and life.
The reaction of [Cu(NCCH3)4]ClO4 with a chelating diimine ligand and 1,2-bis(diphenylphosphane)benzene (bdpp) in dichloromethane solution gives good yields of a series of mixed-ligand copper(I) complexes [Cu(diimine)(bdpp)]ClO4, where the diimine ligands are 2,2?-bipyridine (bpy), 5,5?-dibromo-2,2?-bipyridine (BrbpyBr), 5,5?-diethynyl-2,2?-bipyridine (HCCbpyCCH), 1,10-phenanthroline (phen) and 3,8-dibromo-1,10-phenanthroline (BrphenBr) in complexes 1-5, respectively. All the structures are confirmed by single crystal X-ray structure analysis. A study of the HRMS results suggest that the [Cu(diimine)(bdpp)] + cations for complexes 1-5 are kinetically stable products, and [Cu(bdpp)2]+ is the thermodynamically stable product in DCM solution. In the crystal structures of complexes 1-5, pi…pi and C-H…pi interactions widely exist, among which 4·CH 2Cl2 shows the most striking example. The triple pi…pi interactions within the cation dimer and the rich C-H…pi interactions among the cation dimers are suggested to be the main reasons of the high emissive quantum yield of 18.33% in the solid state under air for complex 4.
