Self-assembly of supermolecular species directed by hydrogen bonding and aromatic π–π stacking interactions

open access: diamondEclética Química, 2018
A new Cu(II) trimers, [Cu3(dcp)2(H2O)8]. 4DMF, with the ligand 3,5-pyrazoledicarboxylic acid monohydrate (H3dcp) has been prepared by solvent method. Its solid-state structure has been characterized by elemental analysis, thermal analysis (TGA and DSC ...

Stacking-induced fluorescence increase reveals allosteric interactions through DNA [PDF]

open access: yes, 2018
From gene expression to nanotechnology, understanding and controlling DNA requires a detailed knowledge of its higher order structure and dynamics. Here we take advantage of the environment-sensitive photoisomerization of cyanine dyes to probe local and ...

4-{(E)-[(2-Hydroxynaphthalen-1-yl)methylidene]amino}-1,5-dimethyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one: a new polymorph (β-phase)

open access: yesIUCrData, 2017
The title molecule, C22H19N3O2, is a new polymorphic modification, viz. the β-phase; the α-phase has been previously published [Liang & Wang (2010). Acta Cryst. E66, o1968–o1969].

d8···d10 RhI···AuI Interactions in Rh 2,6-Xylylisocyanide Complexes with [Au(CN)2]: Bond Analysis and Crystal Effects [PDF]

open access: yes, 2019
Producción CientíficaThe well known [RhL4]n(anion)n structures, with RhI···RhI d8···d8 interactions, are replaced by others with RhI···AuI d8···d10 interactions such as [{RhL4}{Au(CN)2}] (L = 2,6-Xylylisocyanide) or [{RhL4}{Au(CN)2} {RhL4}{Au2(CN)3}·4(

1-Methyl-3-(2-methylphenyl)-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine

open access: yesIUCrData, 2017
In the title compound, C19H16N4, the pyrazolopyrimidine unit is slightly twisted. A combination of π-stacking and offset π-stacking interactions forms columns along the b-axis direction.

Influence of perylenediimide–pyrene supramolecular interactions on the stability of DNA-based hybrids: Importance of electrostatic complementarity

open access: yesBeilstein Journal of Organic Chemistry, 2014
Aromatic π–π stacking interactions are ubiquitous in nature, medicinal chemistry and materials sciences. They play a crucial role in the stacking of nucleobases, thus stabilising the DNA double helix.

Fmoc–RGDS based fibrils: atomistic details of their hierarchical assembly [PDF]

open access: yes, 2016
We describe the 3D supramolecular structure of Fmoc–RGDS fibrils, where Fmoc and RGDS refer to the hydrophobic N-(fluorenyl-9-methoxycarbonyl) group and the hydrophilic Arg-Gly-Asp-Ser peptide sequence, respectively.
