Supramolecular synthon polymorphism in 2 : 1 co-crystal of 4-hydroxybenzoic acid and 2,3,5,6-tetramethylpyrazine.
Co-crystals of 4-hydroxybenzoic acid and 2,3,5,6-tetramethylpyrazine (2 : 1) exhibit the first supramolecular synthon polymorphism in a co-crystal; metastable anti-hierarchic polymorph I converts to stable hierarchic form II.
متن کامل1,1,2,2-Tetracyanocyclopropane (TCCP) as supramolecular synthon.
The 1,1,2,2-tetracyanocyclopropane (TCCP) unit presents a synthetically accessible and versatile synthon that can interact with lone-pair or π-electrons by 'non-covalent carbon bonding'. Complexes of TCCP with common small molecules, anions, aromatics like fullerenes, amino acids and nucleobases were computed at the DFT BP86-D3/def2-TZVP level of theory. Binding energies vary between about -10 ...
متن کاملBalancing supramolecular reagents for reliable formation of co-crystals.
The rational design and synthesis of a supramolecular reagent (SR) composed of two distinct hydrogen bonding sites (pyrazole-benzamide), and four co-crystals resulting from reactions between this SR and a variety of carboxylic acids are described; the observed primary intermolecular interaction is consistent and predictable in each case.
متن کاملIdentification of a new supramolecular synthon in o-anisaldehydes: molecular self-assembly into tapes and staircases
We have shown through a rational design, synthesis and X-ray structural analyses of a set of aldehydes that omethoxybenzaldehydes tend to associate in a centrosymmetric fashion, akin to the carboxylic acids, to give rise to a dimer motif II, which derives stabilization from four C–H/O hydrogen bonds in addition to a dipole–dipole interaction. That the synthon II is credible to be structure dete...
متن کاملOrganizing supramolecular functional dye-zeolite crystals.
Artificial photonic antenna systems have been realised by incorporating organic dyes in a microporous material.[1] We have been using zeolite L in most of our experiments as it has proven to be a very versatile host material. Zeolite L crystals are cylindrically shaped, porous aluminosilicates featuring a hexagonal symmetry. The size and aspect ratio of the crystallites can be tuned over a wide...
