Pop, Flavia; Melan, Caroline; Danila, Ion; Linares, Mathieu; Beljonne, David; Amabilino, David B.; Avarvari, Narcis published an article in 2014, the title of the article was Hierarchical Self-Assembly of Supramolecular Helical Fibres from Amphiphilic C3-Symmetrical Functional Tris(tetrathiafulvalenes).Name: [2,2′-Bipyridine]-3,3′-diamine And the article contains the following content:
The preparation and self-assembly of the enantiomers of C3-sym. compounds incorporating three tetrathiafulvalene (TTF) residues is reported. The chiral citronellyl and dihydrocitronellyl alkyl chains lead to helical one dimensional stacks in solution Mol. mechanics and dynamics simulations combined with exptl. and theor. CD support the observed helicity in solution These stacks self-assemble to give fibers that have morphologies that depend on the nature of the chiral alkyl group and the medium in which the compounds aggregate. An inversion of macroscopic helical morphol. of the citronellyl compound is observed when compared to analogous 2-methylbutyl chains, which is presumably a result of the stereogenic center being further away from the core of the mol. This composition still allows both morphologies to be observed, whereas an achiral compound shows no helicity. The morphol. of the fibers also depends on the flexibility at the chain ends of the amphiphilic components, as there is not such an apparently persistent helical morphol. for the dihydrocitronellyl derivative as for that prepared from citronellyl chains. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Name: [2,2′-Bipyridine]-3,3′-diamine
