Hybrid Organic–Inorganic Rotaxanes, Including a Hetero-Hybrid [3]Rotaxane Featuring Two Distinct Heterometallic Rings and a Molecular Shuttle
Timco, Grigore A.,Fernandez, Antonio,Kostopoulos, Andreas K.,Charlton, Jodie F.,Lockyer, Selena J.,Hailes, Thomas R.,Adams, Ralph W.,McInnes, Eric J. L.,Tuna, Floriana,Vitorica-Yrezabal, Inigo J.,Whitehead, George F. S.,Winpenny, Richard E. P.

[2] and [3] hybrid rotaxanes are reported based on {Ti7M} rings (M is a trivalent metal such as FeIII or GaIII). NMR studies show that [2]rotaxanes can act as molecular shuttles, while EPR studies of [3]rotaxanes show weak interactions between the paramagnetic components of the supramolecular assemblies.
Unexpected lanthanide cation selectivity of bis-b-ketovinylated diaza-18-crown-6 and open-chain diamines: Cooperative effect of the second keto group

New diaza-18-crown-6 based ligands were prepared by the b-ketovinylation of diaza-18-crown-6 by TMS-protected ynones. The obtained N,N0-bis-(3-oxo-3- Arylpropen-1-yl)-7,16-diaza-18-crown-6 ligands (aryl = p-MeOC6H4, p-Me2NC6H4) selectively bind the Ln3? i
Sequence stereoisomerism in calixarene-based pseudo[3]rotaxanes
Talotta, Carmen,Gaeta, Carmine,Pierro, Teresa,Neri, Placido
, p. 2098 - 2101 (2011/06/21)
Two calix[6]arene directional wheels can be ordered in the right stereosequence by their through-the-annulus threading with a rationally designed bis(benzylalkylammonium) axle. These stereoisomeric pseudo[3]rotaxanes can be considered as a minimal "inform
