Electrically conductive metal-organic frameworks (MOFs) provide a rare example of porous materials that can efficiently transport electrical current, a combination favorable for a variety of technological applications. The vast majority of such MOFs are highly anisotropic in both their structures and properties: only two electrically conductive MOFs reported to date exhibit cubic structures that enable isotropic charge transport. Here, we report a new family of intrinsically porous frameworks made from rare earths and hexahydroxytriphenylene that are cubic, porous, and intrinsically conductive with conductivities reaching 10−5 S/cm and surface areas of up to 780 m2/g. By expanding the list of MOFs with isotropic charge transport, these results will help improve our understanding of design strategies for porous electronic materials.<br>

New Square-Planar Bis(Dithiolene) Complexes: Synthesis, Crystallography, and Properties of [Bu4N][MIII(btdt)2] (M=Cu, Au) and [Bu4N]2[PtII(btdt)2] ({btdt}2 - =2,1,3-Benzenethiadiazole-5,6-dithiolate)

The syntheses, crystal structures, and properties of three new coordination complexes [Bu4N][MIII(btdt)2] [M = Cu (1), Au (2)] and [Bu4N]2[PtII(btdt)2] (3) ({btdt}2– = 2,1,3-benzenethiadiazole-5,6-dithiolate) are described. Compounds 1–3 crystallize in a triclinic P-1, and monoclinic P2(1)/c and C2/c space groups, respectively. The {MS4} chromophore lies in almost a square-planar coordination environment in complex 1, but has a slightly distorted square-planar geometry around the central metal ion in compounds 2 and 3. Interactions in the solid state have been studied by intermolecular contacts, in particular, compounds 2 and 3 have been characterized by S⋅⋅⋅N and S⋅⋅⋅S non-covalent interactions among dithiolate complexes, resulting in two- and one-dimensional supramolecular motifs, respectively. Complexes 1–3 show broad absorption bands in the visible region, with that of 3 being sensitive to solvent polarity. Complex 1 exhibits a very low reduction potential for a CuIII-coordination complex, while the PtII complex 3 shows two irreversible oxidative responses at 0.45 V and 0.74 V versus Ag/AgCl, respectively.

Important Approach

ABSTRACTOrganic electroluminescent (EL) diodes based on fluorescent dyes and conducting polymers have attracted the interest of researchers, mainly because of their emission in the visible region and for application to large area portable flat panel display devices, driven at low voltages. Therefore, for the development of higher efficiency polymer EL diodes, the optimal combination of the merits of organic fluorescent dye molecules with that of conjugated polymer is an important approach. We report electroluminescence studies of polymer light emitting diodes (p-LEDs) fabricated with poly[2-(3-thienyl)ethanol n-butoxy carbonylmethyl urethane] (PURET) and its composite with 4-dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H pyran (DCM) dye. These materials have been chosen in view of the fact that PURET exhibits a small overlap between emission and absorption spectra whereas DCM has a good efficiency of trapping both electrons as well as holes. Polyaniline has been utilized as hole injecting layer whereas tris-8-hydroxyquinoline-aluminum as electron injecting layer. Enhanced electroluminescence with bright yellow color has been observed in p-LEDs by the addition of dye.
