Low-potential electrochemical polymerization of carbazole and its alkyl derivatives

High quality polymer films can be easily electrodeposited by low-potential anodic oxidation of carbazole and its alkyl derivatives N-octylcarbazole, N-(6-bromohexyl)carbazole, 1,6-bis(carbazolyl)hexane in boron trifluoride diethyl etherate (BFEE) or mixed electrolytes BFEE + CHCl3. As-formed polymer films showed good redox behavior in monomer free BFEE and were characterized by U-V-Vis, infrared, fluorescence spectroscopy and thermal analysis. Fluorescence spectral studies both in solution and in solid state revealed that as-formed polymer films were good blue light emitters with strong emissions at about 420 and 440 nm, respectively.
