摘要：

1Hand 13C NMR, as well as UVand IR, spectra of a new class of bipyridinium salts made by double quaternization of trans-1,2-bis (4-pyridyl) ethene unit with n-alkyl salts are reported. The effect of quaternization on the 1H and 13C NMR spectra of the salts is discussed. © 1990, Taylor & Francis Group, LLC. All rights reserved.
