  hexakis(oligothienylethynyl)benzene with C6 symmetry shows solvatochromic fluorescence with a marked redshift in emission. Furthermore, the star‐shaped molecule shows a fairly large two‐photon absorption property. Interestingly, the molecule forms fluorescent fibrous materials from hexane, DMF, and isopropyl alcohol owing to its disc‐like structure (see graphic).

  coupling reaction of 5,5'-dibromo-2,2'-bipyridine with TMS and CMe 2 OH protected acetylene allows the synthesis of a disymmetrically functionalized building block which was selectively deprotected from the TMS or the 2-hydroxy-prop-2-yl site.

• A convenient method of producing thiophene linked bipyridine oligomers

  日期：2004.10

  A series of soluble polybipyridine ligands comprising one to five bipyridine modules sandwiched between rigid carboncarbon triple bonds substituted by 3,4-dibutylthiophene repeating units was synthesized. Two different protocols have been explored with the idea to use a divergent/convergent approach starting from bisymmetrically and symmetrically substituted bipyridine modules. At each stage of the iteration two bipy/thiophene modules are connected. The use of triethylsilylacetylene and 2-methylbut-3-yn-2-ol insures an easy entry to pivotal building blocks, which could be selectively deprotected from the TES or 2-hydroxyprop-2-yl sites. All cross-coupling reactions are promoted with palladium(0) tetrakistriphenylphosphine under mild conditions. (C) 2004 Elsevier Ltd. All rights reserved.

  New pi-conjugated oligomers (1-3) combined of thiophene rings, C C units, and phenylene rings were synthesized. The monomer (1) was synthesized by Sonogashira cross-coupling reaction. Lithiation and oxidation of the monomer led to the formation of dimer (2) and trimer (3). Optical and electrochemical properties of compounds 1-3 were studied. The oligomers with thioacetyl moieties were synthesized for self-assembly. (c) 2005 Elsevier Ltd. All rights reserved.

  In this work, we detail the synthesis and photophysical properties of a series of soluble polybipyridine ligands comprising one to five bipyridine units sandwiched between rigid carbon-carbon triple bonds substituted by 3,4-dibutylthiophene repeating units. The dual Sonogashira coupling reaction of 5,5'-dibromo-2,2'-bipyridine with TMS- and (CH3)(2)C(OH)-protected acetylene allows the synthesis of a dissymmetrically functionalized building block which was selectively deprotected at either the TMS or 2-hydroxyprop-2-yl site. Various combinations allow the interconnection of the terminal alkyne to 3,4-dibutyl-2,5-diiodothiophene or 3,4-dibutyl-2-iodothiophene leading to hipyridine frameworks bearing two acetylene-protected groups or one acetylenethiophene/one acetylene-protected function. It is possible therefore to construct dimeric to pentameric bipyridine ligands where the chelating subunit is bridged by a 3,4-dibutyl-2,5-diethynylthiophene spacer and endcapped by a 3,4-dibutyl-2-ethynylthiophene stopper. All cross-coupling reactions are promoted with palladium(0) tetrakistriphenylphosphine under mild conditions. Spectroscopic data for the new oligomers are discussed in terms of the extent of pi-electron conjugation. Upon increasing the number of pi-electrons from 24 to 104, there is a progressive lowering in the energy of absorption and fluorescence transitions, while the emission quantum yields remain essentially constant. The LUMO levels of these large molecules, estimated by cyclic voltammetry, lie in the range -3.06 to -3.18 eV.
