A novel semiconducting oligo(9-fluorenylideneacetic acid) (OFYA) with good redox activity and stability was successfully electrosynthesized by direct anodic oxidation of 9-fluorenylideneacetic acid (FYA) in CH2Cl2 containing boron trifluoride diethyl etherate (BFEE) as the supporting electrolyte. The as-formed OFYA film was readily soluble in dimethyl sulfoxide and tetrahydrofuran, and partly soluble in water, alcohol, acetonitrile and acetone. FT-IR and 1H NMR spectra, together with computational results proved that FYA was probably polymerized through the coupling at C(2) and C(7) positions. Further, OFYA was a typical green light-emitter with maximal emission at 555 nm and its fluorescence quantum yield was distinctly improved in comparison with that of the monomer. The oligomer was also studied by UV-vis spectroscopy, MALDL-TOF mass spectrometry, and thermal analysis, respectively.
