Synthesis of a novel organometallic dendrimer with a backbone composed of platinum-acetylide units

Novel organometallic dendrimers containing platinum-acetylide units in the main chain have been synthesized using 1,3,5-triethyny1-2,4,6-trimethylbenzene (4) as a bridging ligand up to a nonanuclear complex (8).

Modular syntheses of star-shaped pyridine, bipyridine, and terpyridine derivatives by employing sonogashira reactions

A simple and flexible synthesis for a series of star-shaped pyridine, bipyridine, and terpyridine derivatives is reported by using a modular approach that combines the use of a ligand, spacer, and core unit. A fairly efficient method to prepare 4′-nonafloxy-functionalized terpyridine derivatives is described. The building blocks that contain the functionalized pyridine, bipyridine, or terpyridine derivatives were linked to different C3-symmetrical core units. In most cases, Sonogashira reactions were employed in the crucial final steps of the synthesis. A star-shaped dodecafluorinated compound was also prepared in a straightforward fashion. A simple procedure for the preparation of partially silylated 1,3,5-triethynylbenzene derivatives is presented, which provides an approach to C2-symmetrical star-shaped compounds that have only one terpyridine and two terphenyl units as "dummy" ligands. The absorption and emission spectra of the fully conjugated C3-symmetrical pyridine derivatives were systematically investigated, and fairly large Stokes shifts were observed.

Modifying cage structures in metal-organic polyhedral frameworks for H 2 storage

Three isostructural metal-organic polyhedral cage based frameworks (denoted NOTT-113, NOTT-114 and NOTT-115) with (3,24)-connected topology have been synthesised by combining hexacarboxylate isophthalate linkers with {Cu 2(RCOO)4} paddlewheels. All three frameworks have the same cuboctahedral cage structure constructed from 24 isophthalates from the ligands and 12 {Cu2(RCOO)4} paddlewheel moieties. The frameworks differ only in the functionality of the central core of the hexacarboxylate ligands with trimethylphenyl, phenylamine and triphenylamine moieties in NOTT-113, NOTT-114 and NOTT-115, respectively. Exchange of pore solvent with acetone followed by heating affords the corresponding desolvated framework materials, which show high BET surface areas of 2970, 3424 and 3394 m 2 g-1 for NOTT-113, NOTT-114 and NOTT-115, respectively. Desolvated NOTT-113 and NOTT-114 show high total H2 adsorption capacities of 6.7 and 6.8 wt %, respectively, at 77 K and 60 bar. Desolvated NOTT-115 has a significantly higher total H2 uptake of 7.5 wt % under the same conditions. Analysis of the heats of adsorption (Qst) for H2 reveals that with a triphenylamine moiety in the cage wall, desolvated NOTT-115 shows the highest value of Qst for these three materials, indicating that functionalisation of the cage walls with more aromatic rings can enhance the H2/framework interactions. In contrast, measurement of Qst reveals that the amine-substituted trisalkynylbenzene core used in NOTT-114 gives a notably lower H 2/framework binding energy. Copyright
