(1)H and (13)C NMR spectroscopic data of 20 new non-symmetrical compounds were assigned by a combination of 1D and 2D NMR experiments (DEPT, HSQC, and HMBC). These compounds contain a 4-(N,N-dimethylamino)- or 4-(pyrrolidin-1-yl)pyridinium moiety and a 3-nitro-, 3-amino-, or 3-hydroxyphenyl ring, linked by p-xylene, 4,4'-dimethylbiphenyl, 1,2-bis(p-tolyl)ethane, or 1,4-bis(p-tolyl)butane.
