4,4′-Bipyridinium-based ditopic ligands assemble with Pd(ii) centers generating constitutionally dynamic systems in which concentration is a suitable stimulus to influence the speciation between mononuclear [PdL]5+ and dinuclear [Pd2L2]10+ species.

Stoddart's "blue box" (B4+), is one of the most iconic molecules in the recent history of chemistry. This rectangular tetracationic cyclophane has not only the ability to complex a wide variety of aromatic guests in organic or aqueous media, but beca

The self-assembly of [2]rotaxane has been achieved in aqueous media at pD 4 by the simultaneous threading into CB[7] of an appropriate axle ended with acyl hydrazine groups and its concurrent capping with two molecules of a triphenylphosphonium aldeh

We present here an efficient method for the preparation of non-symmetric viologen-containing ditopic ligands, as well as the Pd(ii)/Pt(ii)-directed self-assembly of some of these into metallacyclic receptors. The designed synthetic route, that implie

A series of aryl-extended N-monoalkyl-4,4'-bipyridinium salts L (aryl=1,4-phenyl, 4,4'-biphenyl, 2,6-naphthyl and 9,10-anthracenyl) have been implemented by PdII /PtII -directed self-assembly into constitutionally dynamic systems (CDSs). As a result,

[Abstract] Concentration, temperature and/or solvent polarity control the speciation on the metal-directed self-assembly of a ditopic pyridyl ligand L with cis-protected Pd(II) metal centers. This results into a controllable dynamic system, involving

A family of mono- and dinuclear metallacycles has been self-assembled from (en)M(NO3)2 metal centers (M = PdII or PtII) and 4,4′-bipyridinium/2,7-diazapyrenium-based ligands incorporating quinoline subunits in their structures. These receptors reco

A M2L2 rectangular-shaped metallacycle, obtained by metal-directed self-assembly of a 2-(pyridin-4-ylmethyl)-2,7-diazapyrenium salt and [(en)Pd (NO3)2] (en=ethylenediamine), has been investigated as a molecular receptor for a wide range of aromatic s
