Suzuki–Miyaura cross coupling reaction was used for access to new macrocycles exhibiting oligoethyleneoxide bridges and embedding bithiophene, terthiophene or 3,7-bis(thiophen-2-yl)-N-ethyl-10H-phenothiazine units. The synthesis was performed under various reaction conditions and different coupling types in order to establish the correlation between yields and employed solvents and bases. The structure...
Bithiophene macrocycles with oligo(oxyethylene) loops were synthesized in good yields by reacting 4,4′-bis(hydroxymethyl)-2,2′-bithiophene with ditosylated oligoethyleneglycols. The structures of the macrocycles were elucidated by NMR spectroscopy and MS spectrometry. The electronic and electrochemical properties of the macrocyclic compounds were determined using cyclic voltammetry and UV–Vis spectroscopy.
