Self-assembling triazolophanes: from croissants through donuts to spherical vesicles†
Abstract
Macrocyclic compounds M1–M3 with different ring sizes containing amide and triazole units were synthesized. These triazolophanes displayed a variety of self-assembled structures such as hemi-toroids, toroids, and vesicles in a concentration dependent manner. Detailed ultramicroscopic and crystallographic investigations delineated a hierarchical mechanism of self-assembly.
