This Letter describes a series of [2]rotaxanes featuring a 3,5-diphenylaniline terminus in their dumbbell-shaped component and crown ethers as the macrocyclic component, prepared through imine formation and hydrogen bond—guided self-assembly. Elect

This Letter describes an efficient method for constructing a C3-symmetric [4]rotaxane through hydrogen bond-guided self-assembly and boroxine formation. The reactions proceed under mild conditions in solution, with entropically driven forces promotin

In this study, we synthesized dibenzo[22–30]crown ethers and dumbbell-like secondary ammonium salts having stoppers of varying bulk. These crown ethers formed pseudorotaxanes with the ammonium ions...

New complexes of the bis‐type [Cr(AA)2(AA‐N)(H2O)], where AA stands for L‐amino acidato ligands (L‐leucine, L‐methionine, L‐phenylalanine, L‐serine, L‐threonine) and AA‐N represents monodentate L‐amino acidato ligand with an amino

Adduct ions of monosaccharide molecules with alkali halide triple ions were analyzed by Fast Atom Bombardment (FAB) and Collisionally Activated Dissociation (CAD) techniques. The adduct ions generally appeared in the form of [S+AiXAj]+, where S=monos

This work represents a more precise study of the characteristics of A1XA2+ ions in the gas phase, which can be formed in concentrated electrolyte solutions. In order to obtain the parent ions A1XA2+, a simple system was used, a mixture of two-alkali

Racemization between fac-Λ-(+)546- and fac-Δ-(−)546-[Cr(val)3] (1 and 2) was studied in N,N-dimethylformamide (DMF). These complexes were preferentially converted into bis-type complexes, Λ-(+)546- and Δ-(−)546-[Cr(val)2(val-N)DMF] (4 and 3),
