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.
