N-Centered Chiral Self-Sorting and Supramolecular Helix of Troger's Base-Based Dimeric Macrocycles in Crystalline State.

ABSTRACT: Three stereoisomers of Tröger's Base-based dimeric macrocycles Trögerophane 1 (T1) including one pair of enantiomers ( rac-T1) and one meso isomer ( R _2N S _2N -T1) were obtained and fully characterized by X-ray analysis. In the crystalline stacking state R _2N S _2N -T1 showed heterochiral self-sorting behavior along a axis with cofacial π-π stacking interactions, while rac-T1 showed heterochiral self-sorting behavior along c axis with slipped π-π stacking interactions, respectively. Meanwhile both of them showed homochiral self-sorting behavior along b axis as well as one pair of su
