Novel poly(aryl ether) bearing oligoaniline and carbazole pendants: synthesis and properties
- 311 Downloads
A novel poly(aryl ether) bearing oligoaniline and carbazole pendants (PAEOC) was successfully designed and prepared. Fourier-transform infrared spectroscopy, 1H nuclear magnetic resonance spectroscopy, gel permeation chromatography and X-ray powder diffraction were used to characterize the structure of PAEOC. Its electrochemical properties were investigated using cyclic voltammetry on a CHI 660A Electrochemical Workstation with a conventional three-electrode system. The PAEOC material showed satisfactory electrochromic properties with high contrast value, acceptable switching times, excellent coloration efficiency and admissible stability. Moreover, tunable fluorescence properties have been found by changing the oxidation states of PAEOC.
