Homologous series of regioregular alkylsubstituted oligothiophenes up to an 11-mer
摘要:
A complete series of structurally well-defined butylated oligothiophenes up to an Il-mer was synthesized by a combination of aryl-aryl cross-coupling reactions and cyclization of 1,3-butadiyne precursors with sulfide anions. Palladium-catalyzed cross-coupling of halogenated thiophene units with trimethylsilylacetylene effectively yields ethynylated thiophenes which after deprotection are oxidatively coupled to the corresponding 1,3-butadiynes.

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 photophysicalproperties which were probed by cyclic voltammetry, UV-vis, steady-state emission and transient absorption spectroscopy.
