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 کاملUnexpected helicity control and helix inversion: homochiral helical nanotubes consisting of an achiral ligand.
The ligand tppda has been designed and synthesized as molecular leverage for helicity control when reacted with Cd(2+) ions. The guests MeOH or DMF preferentially stabilize the P-helical isomer, while the guest H2O causes a helix inversion to give the M-helical isomer as the major isomer without any chiral auxiliary.
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 کاملConstitutional self-sorting of homochiral supramolecular helical single crystals from achiral components.
Double-helical architectures obtained from achiral ligands and metal ions present supramolecular homochirality in the single -crystal state under constitutional self-sorting.
متن کاملFormation of triple helical nanofibers using self-assembling chiral benzene-1,3,5-tricarboxamides and reversal of the nanostructure's handedness using mirror image building blocks.
Intertwining triple helical nanofibers with an overall handedness have been formed from self-assembling chiral benzene-1,3,5-tricarboxamides , and , whereas the achiral benzene-1,3,5-tricarboxamide upon self-association gives rise to straight nanofibers without any twist and transmission electron microscopy images of chiral compounds clearly demonstrate that the handedness of the triple helical...
