Cyclodextrin-Based Host–Guest Supramolecular Nanofibrous Composite for Biomedical Applications
Chemistry Proceedings, 2022 Cyclodextrins (CDs) are macrocyclic oligosaccharides, containing between six and eight alpha(1 → 4)-linked glucopyranoses. CDs have a hydrophobic cone-shaped internal cavity and a hydrophilic exterior surface.

Uranium(III) Coordination Chemistry and Oxidation in a Flexible Small-Cavity Macrocycle [PDF]
Organometallics, 2015 U(III) complexes of the conformationally flexible, small-cavity macrocycle trans-calix[2]benzene[2]pyrrolide (L)2–, [U(L)X] (X = O-2,6-tBu2C6H3, N(SiMe3)2), have been synthesized from [U(L)BH4] and structurally characterized. These complexes show binding of the U(III) center in the bis(arene) pocket of the macrocycle, which flexes to accommodate the ...

Photochromism change by conformation control in macrocyclic boronic ester cavity [PDF]
Acta Crystallographica Section A Foundations and Advances, 2014 N-salicylideneaniline derivatives are known to show photochromism by UV light, and it depends on the molecular conformation in the crystal. The twisted molecule is photochromic but the planar one is not[1,2]. N-salicylidene-2-aminopyridine (2SAP) always has a planar conformation due to the chemical structure without steric hindrance, therefore 2SAP is ...
