Original Contribution


A novel multifunctional poly(amic acid) bearing oligoaniline, fluorene groups (PAAOF) has been prepared through the one-step synthetic route. The structure of PAAOF was confirmed via nuclear magnetic resonance (NMR), Fourier-transform infrared spectra (FTIR), and gel permeation chromatography (GPC). Moreover, the electrochemical measurement results revealed that PAAOF material have an expected electrochemical activity, and good electrochromic properties with high contrast value and satisfactory coloration efficiency. The photophysical properties of the as-synthesized PAAOF at various oxidation states were studied. The results indicated that the fluorescence of PAAOF could be tuned by modulating the oxidation states of oligoaniline segments. In the fluorescence tuning, the fluorene groups are fluorophore, and the oligoaniline segments are used as regulatory unit.


A novel multifunctional poly(amic acid) containing oligoaniline and fluorene groups was synthesized. This material shows reversible electroactivity and excellent electrochromic properties. Interesting photophysical properties of the as-synthesized PAAOF at various oxidation states were found and studied in detail
