H-1 NMR spectral studies on the polymerization mechanism of indole and its derivatives

关键字:conducting polymers; polyindoles; polymerization mechanism; hydrogen nuclear magnetic resonance; boron trifluoride diethyl etherate

摘要:The existence of N-H bond according to the hydrogen nuclear magnetic resonance (H-1 NMR) spectra of polyindole and its derivatives, such as poly(5-bromoindole), poly(5-cyanoindole), poly(5-nitroindole), poly (5-methylindole), proved polymerization of high-quality polyindoles, which were electrosynthesized from middle strong Lewis acid boron trifluoride diethyl etherate (BFEE) and its mixed electrolytes with additional diethyl ether, occurred at 2,3-position. The elongation of the conjugation length made the chemical shift of all the protons of polyindoles to lower field in comparison with those of monomers. (c) 2005 Elsevier B.V. All rights reserved.
