Mesomorphic behaviour in copoly(ester-imide)s of poly(butylene-2,6-naphthalate) (PBN)

Mesomorphic Behaviour of N-4-hexadecylpyridinium Chloride

Unusual mesomorphic behaviour of an ethynyl-substituted phthalocyanine.

An ethynyl-substituted nickel(II) phthalocyanine has been synthesised and its thermotropic properties studied; optical microscopy, differential scanning calorimetry (DSC) and X-ray diffraction (XRD) techniques revealed an unusual mesomorphic behaviour observed for the first time in phthalocyanine systems where each disk of the hexagonal columnar mesophase is formed by two ethynyl-substituted ph...

Behaviour of mesomorphic systems of conformationally rigid and flexible molecules in external orienting fields

Mesomorphic Lamella Rolling of Au in Vacuum

Lamellar nanocondensates in partial epitaxy with larger-sized multiply twinned particles (MTPs) or alternatively in the form of multiple-walled tubes (MWTs) having nothing to do with MTP were produced by the very energetic pulse laser ablation of Au target in vacuum under specified power density and pulses. Transmission electron microscopic observations revealed (111)-motif diffraction and low-...

Mechanochemical N-alkylation of imides

The mechanochemical N-alkylation of imide derivatives was studied. Reactions under solvent-free conditions in a ball mill gave good yields and could be put in place of the classical solution conditions. The method is general and can be applied to various imides and alkyl halides. Phthalimides prepared under ball milling conditions were used in a mechanochemical Gabriel synthesis of amines by th...
