Structures of the Chiral Dimethylpyridino-18-crown-6-alpha-(1-naphthyl)ethylammonium Perchlorate Complex as Determined by T1 Relaxation and Molecular Modeling

摘要

The flexibility of the complexed ligand causes C relaxation times of allperiphery carbons to drop without significant selectivity. Rotational energy barrier measurements of the methyl groups of the complexed ligand also show that the (SS)-host-(R)-guest is the more stable complex.
