Intramolecularly enhanced molecular tweezers with unusually strong binding for aromatic guests in unfavorable solvents

Molecular tweezers using aromatic interactions for binding normally work best in polar instead of nonpolar solvents due to the strong solvophobic effect in the binding.

Narcissistic chiral self-sorting of molecular face-rotating polyhedra

Narcissistic chiral self-sorting prevailed in the assembly of molecular face-rotating polyhedra from a C3h building block 5,5,10,10,15,15-hexabutyl-truxene-2,7,12-tricarbaldehyde and racemic mixtures of 1,2-diamines.

Taking advantage of Co(II) induced enhanced VCD for the fast and sensitive determination of enantiomeric excess

Large Co(II)-induced VCD signals provide a method for determining the enantiomeric excess of α-amino acids. This strategy can be followed for building new VCD protocols.

Backbone conformation affects duplex initiation and duplex propagation in hybridisation of synthetic H-bonding oligomers

Forming the first intramolecular H-bond is straightforward, but forming subsequent intramolecular interactions is difficult, because the backbone imposes more severe constraints.

Effects of cucurbit[n]uril (n = 7, 8, 10) hosts on the formation and stabilization of a naphthalenediimide (NDI) radical anion

The binding interactions of a NDI diammonium dichloride salt with cucurbit[n]uril (CB[n], n = 7,8, 10) and the formation process of a NDI radical anion upon photoexcitation of the NDI derivative in the presence of a CB[n] host have been investigated.

Push–pull quinoidal porphyrins

Quinoidal porphyrins with electron-donating 1,3-dithiolane and electron-withdrawing dicyanomethylene groups form tightly π-stacked layer structures, despite their curved geometries and bulky aryl substituents. The crystal structures of these quinoidal porphyrins indicate that there is no significant contribution from singlet biradical or zwitterionic resonance forms.

Complete tetraglycosylation of a calix[4]arene by a chemo-enzymatic approach

It was demonstrated that a calixarene can be a substrate for glycosyltransferases and thanks to an exhaustive glycosylation a multivalent tetralactosaminyl calix[4]arene was obtained.
