Amplification of chirality in benzene tricarboxamide helical supramolecular polymers.
The chirality of benzene tricarboxamides is expressed and amplified into the helicity of self-assembled columnar aggregates according to 'sergeants and soldiers' and 'majority rules' principles; the strength of the amplification is analysed quantitatively and the effect of the number of chiral groups in the sergeants is studied.
متن کاملSolvent-dependent amplification of chirality in assemblies of porphyrin trimers based on benzene tricarboxamide.
Self-assembling achiral and chiral porphyrin trimers based on benzene tricarboxamide exhibit amplification of chirality only in solvents in which the assemblies are dynamic enough to rearrange their constituting components.
متن کاملThe energetics of ion-pair and hydrogen-bonding interactions in a helical peptide.
A single pair of Glu and Lys residues has been placed at four different spacings, and in both orientations, in an otherwise neutral alanine-glutamine peptide helix, and the contribution to helix stability of the different Glu-Lys interactions has been measured. The contribution from the interaction of each charged side chain with the helix macrodipole has also been determined. A side-chain inte...
متن کاملHelical organization of chiral binaphthyl tetrathiafulvalene primary amides through hydrogen bonding interactions
Chiral tetrathiafulvalenes, (R) or (S), or racemic, (R,S), are obtained from a phosphite-mediated cross coupling reaction of a 1,3-dithiole-2-thione derivative bearing one binaphthol moiety, and are transformed into binaphthol-based tetrathiafulvalene ortho-diamides. The X-ray crystal structures of five intermediate chiral 1,3-dithiole-2-one and 1,3-dithiole-2-thione derivatives reveal the form...
متن کاملA hydrogen bonding motif for forming extended assemblies.
Oligoamide strands containing tertiary amide groups were found to share a basic structural motif that promotes the formation of H-bonded, chain- or tape-like supramolecular assemblies.
