Adsorption of imidazole on Au(111) surface: Dispersion corrected density functional study [PDF]
, 2016 We use density functional theory in the generalized gradient approximation to study the adsorption of imidazole on the Au(111) surface and account for dispersion effect using Grimme's empirical dispersion correction technique.

Solution-phase synthesis of pyrrole-imidazole polyamides [PDF]
, 2009 Pyrrole−imidazole polyamides are DNA-binding molecules that are programmable for a large repertoire of DNA sequences. Typical syntheses of this class of heterocyclic oligomers rely on solid-phase methods. Solid-phase methodologies offer rapid assembly on

Evolutionary convergence in the biosyntheses of the imidazole moieties of histidine and purines. [PDF]
PLoS ONE, 2018 The imidazole group is an ubiquitous chemical motif present in several key types of biomolecules. It is a structural moiety of purines, and plays a central role in biological catalysis as part of the side-chain of histidine, the amino acid most ...

2-[(1H-Imidazol-2-yl)disulfanyl]-1H-imidazole [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 In the title molecule, C(6)H(6)N(4)S(2), a twofold rotation axis passes through the mid-point of the S-S bond. The C-S-S-C torsion angle is 83.62 (17)°. π-π stacking between imidazole rings of adjacent mol-ecules is observed in the crystal structure, the centroid-centroid distance being 3.447 (2) Å. Inter-molecular N-H⋯S hydrogen bonding results in the
