AbstractThe introduction of branching in multi‐thiophene semiconductors, although granting the required solubility for processing, results in an increased molecular fluxionality and a higher level of distortion, thus hampering π conjugation. Accordingly, branched oligothiophenes require rationalization of their structure–reactivity relationships for target‐oriented design and optimization of the synthetic effort. Our current research on spiderlike oligothiophenes affords deep insight into the subject, and introduces new, easily accessible molecules with attractive functional properties. In particular, a regular series, T′XY, of five new multi‐thiophene systems, T′53, T′84, T′115, T′146, and T′177, constituted by five, eight, 11, 14, and 17 thiophene units, respectively, their longest α‐conjugated chain consisting of tri‐, tetra‐, penta‐, hexa‐, and heptathiophene moieties, respectively, has been synthesized and fully characterized from the structural, spectroscopic, and electrochemical point of view. The electronic properties of the monomers and their electropolymerization ability are discussed and rationalized as a function of their molecular structure, particularly in comparison with the series of 5‐(2,2′‐dithiophene)yl‐persubstituted α‐oligothiophenes (TXY) previously reported by us. These oligothiophenes are easily accessible materials, with promising properties for applications as active layers in multifunctional organic devices including solar cells.

AbstractWe report a modified seed‐mediated approach for the synthesis of uniform Au nanocages (AuNCs). HAuCl4 was reduced in an aqueous mixture of hexamethylenetetramine (HMT), poly(N‐vinyl‐2‐pyrrolidone) (PVP), and AgNO3. The nanocages were (54.6±13.3) nm in outer‐edge length and about 12 nm in wall thickness. The structure of the AuNCs was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray energy dispersive spectroscopy (EDS), X‐ray diffraction (XRD), Fourier‐transform infrared (FTIR) spectroscopy, and X‐ray photoelectron spectroscopy (XPS). Morphological changes associated with the seed‐mediated growth of Au nanoparticles (AuNPs) in the absence of HMT or PVP were examined. The results demonstrate that both PVP and HMT play important roles in the formation of the nanocage structure. The function of AgNO3 was also studied. A possible formation mechanism for the AuNCs was investigated by monitoring TEM images of the Au nanostructures formed at various reaction times. The electrocatalytic activity of the AuNCs towards the oxidation of glucose was explored, and a nonenzymatic glucose sensor with high sensitivity and good stability was further fabricated. To the best of our knowledge, this is the first report of the preparation of AuNCs by a seed‐mediated strategy and of the application of AuNCs in the electrocatalytic oxidation of glucose. Our results should facilitate the creation of novel nanomaterials with various morphologies and the exploration of their applications in nanotechnological, optical, catalytic, and materials science fields.

AbstractEnantiomerically pure metalated 2‐(1‐naphthyl)ferrocene (NpFc) derivatives NpFcM (M=SnMe3, HgCl) were prepared and characterized by multinuclear NMR and UV/Vis spectroscopy, cyclic voltammetry, and elemental analysis. Optical rotation measurements were performed and the absolute configuration of the new planar chiral ferrocene species was confirmed by single‐crystal X‐ray diffraction analysis. The mercuriated species NpFcHgCl proved suitable as a reagent for the preparation of the chiral organoborane Lewis acid NpFcBCl2, which can in turn be converted to other ferrocenylboranes by replacement of Cl with nucleophiles. The highly Lewis acidic perfluoroarylborane derivatives NpFcB(C6F5)Cl and NpFcB(C6F5)2 were successfully prepared by treatment with CuC6F5. The structures were studied by single‐crystal X‐ray diffraction and variable‐temperature 19F NMR spectroscopy, which suggested that π stacking of a C6F5 group on boron with the adjacent naphthyl group is energetically favorable. UV/Vis absorption spectroscopy and cyclic voltammetry measurements were performed to examine the electronic properties of these novel redox‐active chiral Lewis acids.
Dumbbell‐Shaped Dinuclear Iridium Complexes and Their Application to Light‐Emitting Electrochemical Cells

Published: June 2010

AbstractA novel family of dumbbell‐shaped dinuclear complexes in which an oligophenyleneethynylene spacer is linked to two heteroleptic iridium(III) complexes is presented. The synthesis, as well as the electrochemical and photophysical characterization of the new complexes, is reported. The experimental results are interpreted with the help of density functional theory calculations. From these studies we conclude that the lowest triplet excited state corresponds to a 3π–π* state located on the conjugated spacer. The presence of this state below the 3MLCT/3LLCT emitting states of the end‐capping IrIII complexes explains the low quantum yields observed for the dinuclear complexes (one order‐of‐magnitude less) with respect to the mononuclear complexes. The potential application of the novel dinuclear complexes in optoelectronic devices has been tested by using them as the primary active component in double‐layer light‐emitting electrochemical cells (LECs). Although the luminance levels are low, the external quantum efficiency suggests that a near‐quantitative internal electron‐to‐photon conversion occurs in the device. This indicates that the emission inside the device is highly optimized and that the self‐quenching associated with the high concentration of the complex in the active layer is minimized.
Formation and Rearrangement of SnII Phosphanediide Cages

Published: June 2010

AbstractThe room‐temperature reactions of Sn(NMe2)2 with less sterically demanding primary phosphines (RPH2) give the homoleptic phosphanediide compounds [SnPR]n in high yields (R=tBu (1 a), cyclohexyl (1 b), 1‐adamantyl (1 c)). However, the room‐temperature reaction of Mes*PH2 (Mes*=2,4,6‐tBu3C6H2) with Sn(NMe2)2 gives the model intermediate [{SnPMes*}2(μ‐NMe2)SnP(H)Mes*] (3), together with the product of complete deprotonation [SnPMes*]3 (4). Phosphorusphosphorus bonded products are produced in these reactions at elevated temperatures. If the reaction producing 1 a is heated to reflux then [tBuP(H)P(H)tBu] is produced as the major product (together with tin metal). The novel octanuclear cage [{SnPtBu}7Sn(PtBu)3] (2) can also be isolated in low yield, resulting from formal addition of the heterocyclic stannylene [(tBuP)3Sn] to a SnP single bond of the intact structure of 1 a. Prolonged heating of the reaction producing 3 and 4 leads to the formation of the diphosphene [PMes*]2 (5) and tin metal. The X‐ray structures of the heptamer 1 a (n=7), octanuclear 2 and trinuclear 3 are reported.
Al3Li4(BH4)13: A Complex Double‐Cation Borohydride with a New Structure

AbstractThe new double‐cation Al–Li–borohydride is an attractive candidate material for hydrogen storage due to a very low hydrogen desorption temperature (∼70 °C) combined with a high hydrogen density (17.2 wt %). It was synthesised by high‐energy ball milling of AlCl3 and LiBH4. The structure of the compound was determined from image‐plate synchrotron powder diffraction supported by DFT calculations. The material shows a unique 3D framework structure within the borohydrides (space group=P‐43n, a=11.3640(3) Å). The unexpected composition Al3Li4(BH4)13 can be rationalized on the basis of a complex cation [(BH4)Li4]3+ and a complex anion [Al(BH4)4]−. The refinements from synchrotron powder diffraction of different samples revealed the presence of limited amounts of chloride ions replacing the borohydride on one site. In situ Raman spectroscopy, differential scanning calorimetry (DSC), thermogravimetry (TG) and thermal desorption measurements were used to study the decomposition pathway of the compound. Al–Li–borohydride decomposes at ∼70 °C, forming LiBH4. The high mass loss of about 20 % during the decomposition indicates the release of not only hydrogen but also diborane.
