Nature of the mesophase of a conducting charge transfer complex : neither discotic nor calamitic
2014 We describe the structure of the mesophase of a conducting charge transfer complex formed by a donor substituted by four long paraffinic chains and TCNQ as acceptor. In the mesophase the donor cores remain in stacks with a short core-to-core distance (3.6 A). The presence of paraffinic chains favours a layer structure, the stacks being localized in the lamellae and TCNQ likely filling the ...
متن کاملSupramolecular Liquid Crystals. Self-Assembly of a Trimeric Supramolecular Disk and Its Self-Organization into a Columnar Discotic Mesophase
6,7-Bis(alkyloxy)-2,3-dihydrophthalazine-1,4-diones self-assemble into lactim-lactam trimeric disks in solution as demonstrated by SEC and NMR. With suitable substituents, as in Phthal8, Phthal12, and Phthal16, these disks self-organize into a thermotropic, columnar, discotic phase. The disubstituted phthalhydrazide unit thus represents a general motif for the recognition-induced generation of ...
متن کاملMesophase behaviour of polyhedral particles.
Translational and orientational excluded-volume fields encoded in particles with anisotropic shapes can lead to purely entropy-driven assembly of morphologies with specific order and symmetry. To elucidate this complex correlation, we carried out detailed Monte Carlo simulations of six convex space-filling polyhedrons, namely, truncated octahedrons, rhombic dodecahedrons, hexagonal prisms, cube...
متن کاملGlucosylation of sucrose laurate with cyclodextrin glucanotransferase.
Sucrose monolauroyl esters were found to serve as substrates for cyclodextrin glucanotransferase (CGTase)-catalyzed transglucosidation reactions, affording new sucrose esters that have an additional 1-3 glucose residues on the pyranose ring of the sucrose moiety in the ester.
متن کاملNovel banana-discotic hybrid architectures
Here we present the design and synthesis of novel banana-discotic dimers and banana-bridged discotic dimers. The chemical structures have been characterized by spectral techniques and elemental analysis. The thermal behaviors of the compounds have been investigated by polarizing optical microscopy and differential scanning calorimetry. None of these synthesized compounds exhibit any liquid crys...
