Abstract: A new electroactive poly(aryl ether ketone) macrocyclic oligmer with phenyl-capped tetramer was synthesized by the modified pseudo-high-dilution method, whose structure with a rigid molecular backbone contains a cavity of well-defined size. The oligomer was characterized with mass spectrometry, IR and 1H NMR, 13C NMR spectroscopies. Its redox property was checked by cyclic voltammetry and chemical oxidation process was monitored by UV spectroscopy. We found that it has a reversible electrochemical property like common oligoanilines. Combined with its well-defined structure, the oligmer is expected to act as a kind of host molecules which are capable of molecular recognition.

Key words: Electroactivity, Macrocyclic oligomer, Oligoanilines, Poly(aryl ether ketone)
