  p-Diethynylbenzene-based molecular wires, Fe–C C-p-C6H2X2–C C–Fe [Fe= Fe(η5-C5Me5)(dppe)]: Synthesis, substituent effects and unexpected formation of benzodifuran complex

  摘要：

  A series of p-diethynylbenzene- based molecular wires, Fe-C C-p-C6H2X2-C C-Fe (3) (Fe = FeCp* (dppe)), is prepared and their wire-like performance is estimated on the basis of the K-C and V-ab values. It has been revealed that electron-donating substituents (X) improve the performance. The benzodifuran complex 4 unexpectedly formed from the derivative with X = OH shows the performance comparable to 3. (C) 2009 Elsevier B.V. All rights reserved.

  A novel class of rod-coil type-organoboron polymers with p-phenylene-ethynylene as the rod segment and long alkyl chain (decyl group) as coil segment has been prepared from a Sonogashira-Hagihara coupling reaction of a BODIPY-based monomer having bis-iodophenyl and decyl groups with diyne monomers, 1,4-diethynylbenzene (a), 1,4-diethynyl-2,5bis(trifluoromethyl)benzene (b), and 2,7-diethynyl-9,9-dihexyl-9H-fluorene (c). The characterization by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the strong tendency of the obtained polymers, 2a, 2b, and 2c, to self-assemble into particles in solution and as-casted films on a mu m-nm scale. Especially, 2a showed the presence of nm-sized particles and mu m-sized fiber-like structures formed by aggregation of each particle. Further, in CHCl3, the gelation of 2a by three-dimensional aggregation of each fiber was observed at room temperature after 24 h. Their luminescent properties showed high energy transfer efficiency from pi-conjugated polymer linkers to BODIPY moieties (Phi(F) > 71%).

  A series of binuclear ruthenium vinyl complexes [RuCl(CO)(PMe3)(3)](2)(mu-CH=CH-Ar-CH=CH) (Ar = C6H4 (6a), C6H3CH3 (6b), C6H3OCH3 (6c), C6H3F (6d), C6H3Cl (6e), C6H3Br (6f), C6H3CN (6g), C6H3NO2 (6h), C6H2(CH3)(2)-2,5 (6i), C6H2(OCH3)(2)-2,5 (6i), C6H2(F)(2)-2,5 (6k), C6H2(CF3)(2)-2,5 (6l), and C6H3CF3 (6m)) have been prepared. The respective products have been characterized by elemental analyses, NMR spectrometry, and UV/vis spectrophotometry. The structures of 6h, 6i, and 6j have been established by X-ray crystallography. Electrochemical studies have revealed that intermetallic electron communication between the two Ru centers may be fine-tuned by modification of the bridging spacers, that is, by introducing one or two substituent groups on the 1,4-diethenylphenylene bridge. Electron-releasing substituents have been found to facilitate electron communication between the two metal centers.
