The ability to tune the structural properties with respect to size, polarity, and terminal functionalities makes dendrimers a highly attractive class of compounds with potential biological and catalytic applications.In the present study, Janus (J) and Twi

Hiremath, Uma S.

The first examples of mesogenic bis(N-salicylideneaniline)s (BSANs), wherein two lipophilic (half-disk shaped) entities are interlinked through the dihydroxydiformylbenzene core, were synthesized and characterized. In particular, three constitutional (positional) isomeric BSANs were prepared by the facile twofold condensation of 3,4,5-tris(alkoxy)anilines with 2,3-dihydroxyterephthalaldehyde, 4,6-dihydroxyisophthalaldehyde, and 2,5-dihydroxyterephthalaldehyde and their structures were established by elemental analyses, FT-IR, 1H NMR, and 13C NMR. Proton NMR experiments demonstrated their existence in enol-imine (OH) form solely. Polarizing optical microscopic, differential scanning calorimetric, and powder X-ray diffraction studies evidenced the occurrence of columnar mesomorphism in two sets of isomers.

Discotic hydrazone molecules are of particular interest as they form discotic phases where the discs are rigidified by intramolecular hydrogen bonds. Here, we investigate the thermotropic behavior and solid-state organizations of three discotic hydrazone
A generalized supramolecular strategy for self-sorted assembly between donor and acceptor gelators

supporting information; experimental part, p. 8922 - 8924 (2011/09/30)
An effective supramolecular strategy for self-sorting between naphthalene-diimide (NDI) acceptor and dialkoxy-naphthalene (DAN) donor organogelators is reported. The concept is based on mismatch in the placement of the two amide functionalities in the don

(Chemical Equation Presented) Two series of a unique class of columnar liquid crystals derived from tris(N-salicylideneaniline)s [TSANs] in which the proton and the electron interact with each other through the H-bonding environment are reported. The synt

Complexation of non-mesomorphic dithiooxamide ligands to Pt(II) leads to square planar complexes which exhibit mesomorphic properties. The synthesis of these complex was accomplished in three steps: the formation of bisamides, starting from conveniently s
Effects of isocyanide substituents on the mesogenic properties of halogeno(isocyanide)gold complexes: Calamitic and discotic liquid crystals
Coco, Silverio,Espinet, Pablo,Marti-Alvarez, Jose M.,Levelut, Anne-Marie
, p. 19 - 23 (2007/10/03)
The liquid crystal behaviour of linear [AuX(CNC6H4OCnH2n+1)] (X = halogen) complexes is tuned by systematically changing the structure of the isocyanide ligand. The changes studied are lateral fluorination at the 2- and 3-positions of the phenyl ring and modification of the rod-like structure of the complexes by addition of two alkoxy chains at the meta positions. None of the free isocyanides used here are liquid crystals, but all the gold complexes prepared display mesomorphic properties, except iodo(2-fluoro-4-butoxyphenyl isocyanide)gold(I). The (2- and (3-fluorophenyl isocyanide)gold(I) complexes show smectic A mesophases, except the 2-fluoro derivative with n = 6, which shows a nematic phase, while the (3,4,5-trialkoxyphenyl isocyanide)gold compounds display columnar hexagonal phases at room temperature.
