Syntheses and Characterizations of Luminescent Complexes (BINAP)Pt(C≡CC6H4R-p)2 (R = H, 1; CH3, 2) (BINAP = 2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl)

摘要

cqvip:[(BINAP)Pt(C≡CC6H4R-p)2] (R = H, 1; CH3, 2) (BINAP = 2,2’-bis(diphenylphos- phino)-1,1’-binaphthyl) were synthesized and characterized by X-ray crystallography. Complex 1 crystallizes in triclinic, space group P1 with a = 11.699(3), b = 12.512(3), c = 15.611(4) ’, α = 93.277(3), β = 97.626(2), γ = 97.375(14)o, V = 2239.9(9) ’3, Mr = 1014.92, Z = 2, Dc = 1.505 g/cm3, F(000) = 1010, μ(MoKα) = 3.244 mm–1, the final R = 0.0338 and wR = 0.0905 for 7738 observed reflections (I > 2σ(I)). Complex 2 crystallizes in monoclinic, space group P21/n with a = 18.03690 (10), b = 13.06060(10), c = 21.6913(3) ’, β = 96.5430(10)o, V = 5076.60(9) ’3, Mr = 1132.94, Z = 4, Dc = 1.482 g/cm3, F(000) = 2272, μ(MoKα) = 2.973 mm–1, the final R = 0.0481 and wR = 0.0893 for 8916 observed reflections (I > 2σ(I)). Both complexes emit intensively photoluminescence in both solid state and fluid solution due to MLCT (Pt→–C≡CC6H4R-p) emissive state.
