Hydrogen-bonded supramolecular assemblies of folic acid with simple hexoses

Multiple Hydrogen-Bonded Supramolecular Polymers

Mesoscopic correlation of supramolecular chirality in one-dimensional hydrogen-bonded assemblies.

The ordering of 4-[trans-2-(pyrid-4-yl-vinyl)] benzoic acid, a two-dimensional chiral species, was studied by scanning tunneling microscopy at noble metal surfaces. Homochiral molecules self-assemble in supramolecular chiral hydrogen-bonded twin chains, which order in nanogratings where the supramolecular chirality is strictly correlated over the entire microm domains without intimate molecular...

Supramolecular gel from folic acid with multiple responsiveness, rapid self-recovery and orthogonal self-assemblies.

Through a good/poor solvent strategy, native folic acid (FA) which behaves as a super-gelator in DMSO-water system can be successfully employed to construct supramolecular gels. The system exhibited morphological evolution with the increase of FA concentration; various phases such as vesicles, fiber/vesicles, fiber/nanoparticles, nanoparticles were probed. In the self-assembly process, l-glutam...

Supramolecular hydrogen-bonded structure of a 1:2 adduct of melamine with boric acid

Boric acid (B) forms a 2:1 hydrogen-bond adduct, M·2B, with melamine (M), wherein, a finite tetrameric ribbon of boric acid forms hydrogen bonds with the nitrogen donor sites of M. Hydrogen-bonded layers of B and M in the bc-plane are connected by boric acid units along the a-axis to give a three dimensional structure. Interestingly, one of the amino groups of M does not participate in hydrogen...

Hydrogen-bonded self-assemblies in a polychlorotriphenylmethyl radical derivative substituted with six meta-carboxylic acid groups.

The synthesis, self assembly and magnetic properties of a polychlorotriphenylmethyl radical, substituted with six meta-carboxylic groups, are reported showing that radical-radical hydrogen bonds in the solid state yield to very weak intermolecular ferromagnetic interactions.
