AbstractA novel Pt(II) complex [(L)PtCl] (HL = 4-{4p-[N-(4-(9-carbazole))butyl-N-phenyl] aniline}-6-phenyl-2,2'-bipyridine) has been synthesized and verified by (1)H NMR, elemental analysis and X-ray crystallography. The crystal (C(44)H(35)N(4)ClPt, M(r) = 850.30) belongs to monoclinic system, space group P2(1)/c, with a = 21.864(6), b = 9.306 (3), c = 17.240(5) angstrom, beta = 96.483(6)degrees, Z = 4, V = 3485.3(16) angstrom(3), D(C) = 1.620 g/cm(3), mu(Mo-K alpha) = 4.141 mm(-1), F(000) = 1688, R(1) = 0.0591, wR(2) = 0.0976. The coordinate geometry of the Pt atom is a distorted square planar configuration. The complex molecules are stacked by a weak pi-pi interaction in a head-to-tail fashion along the b axis to form 1D chain and the alternating 10 chains are packed to form the 2D lamellar system. The complex shows an intense metal-to-ligand charge transfer ((1)MLCT) (d pi(Pt) -> pi*(L)) transitions (epsilon similar to 2 x 10(4) dm(3) mol(-1) cm(-1)) at 448 nm in the UV-Vis absorption spectrum and a strong phosphorescence at 592 nm in CH(2)Cl(2) solution at room temperature. An intramolecular energy transfer process from the carbazole unit to the arylamine-modified (C boolean AND N boolean AND N)PtCl] emissive center exists in the complex. (C) 2010 Elsevier B.V.
