“…Surprisingly, in this case the diol group does not induce a smectic mesophase. This is in contradiction to our experience with diol mesogens containing calamitic structural units different from the cyanobiphenyl system (compare compounds 3 [4] and 4 [5] in figure 1). Also the cyanobiphenyl derivative 5, which differs from 1 in the structure of the hydrophilic diol group, exhibits a monotropic nematic phase.…”

The crystal and molecular structures of (R)-4'-(2,3-dihydroxypropyloxy)-4-cyanobiphenyl, 1 and 4'-(cis-cis-3,5-dihydroxycy~l0hexyloxy)-4-cyanobiphenyl, 5 have been determined. The packing of compound 1 occurs in sheets, with a dense hydrogen bonding network within the layer of one sheet and to the next sheet, whereby the cyano groups are incorporated into the hydrogen bonding network. The hydrogen bonding scheme of compound 5 involves a water molecule; there is some disorder with regard to the hydrogen atoms bound to the water molecules.

“…These results suggest that the 1,2-diol groups are capable of forming stable hydrogenbonded networks and induce layered liquid-crystalline molecular association. 72 73 74 The effect of the diol groups at the end of the alkyl chains has been compared for compounds 75 and 76 [160]. Compound 75 has a structure that incorporates diol moieties into its parent compound 76.…”

~ Spri ngerThe series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table. It focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant.As a rule, contributions are specially commissioned. The editors and publishers will, however, always be pleased to receive suggestions and supplementary information. Papers are accepted for Structure and Bonding in English.In references Structure and Bonding is abbreviated Struct. Bond. and is cited as a journal.Springer www home
