  摘要：

  5,5'-二溴-2,2'-联吡啶与 TMS 和 CMe 2 OH 保护的乙炔的双重 Sonogashira 偶联反应允许合成从 TMS 或 2-羟基-丙二醇选择性脱保护的双对称官能化结构单元-2-基位点。各种组合允许末端炔烃与 3,4-二丁基-2-碘噻吩或 3,4-二丁基-2,5-二碘噻吩互连，从而形成带有两个乙炔基噻吩单元或一个噻吩/一个乙炔官能团的联吡啶骨架。可以构建双位或三位联吡啶配体，其中螯合亚基由 3,4-二丁基-2,5-二乙炔基噻吩间隔物桥接，并由 3,4-二丁基-2-乙炔基噻吩终止剂封端。

  A convenient method of producing thiophene linked bipyridine oligomers

  摘要：

  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.

  A facile and original synthesis of four 2,2'-bipyridine (bipy) ligands grafted with thiophene subunits is described using phase transfer experimental conditions: related Ru(II) complexes exhibit well-defined redox and photophysical properties which were probed by cyclic voltammetry, UV-vis, steady-state emission and transient absorption spectroscopy.

  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.
