Inclusion compound based approach to arrays of artificial dipolar molecular rotors: Bulk inclusions

We examine the insertion of two dipolar molecular rotors as guests into a host, tris(o-phenylenedioxy)cyclotriphosphazine (TPP, 1), using differential scanning calorimetry, solid-state NMR, powder X-ray diffraction, and dielectric spectroscopy. The rotors are 1-(4′-n-pentylbiphenyl-4-yl)-12-(2,3- dichlorophenyl)-p-dicarba-closo-dodecaborane and 1,12-bis(2,3-dichlorophenyl)-p- dicarba-closo-dodecaborane. Both enter the bulk even though their nominal diameter exceeds the nominal channel diameter and although a closely related rotor, 1-n-hexadecyl-12-(2,3-dichlorophenyl)-p-dicarba-closo-dodecaborane, is known to produce a surface inclusion compound. Rotational barriers of 5.4-9.3 kcal/mol were found for the dichlorophenyl rotator contained within the TPP channel. Clearly, van der Waals diameters in themselves do not suffice to predict TPP channel entry. It is suggested that the efficacy of the p-carborane stopper is reduced by the presence of the two relatively bulky adjacent benzene rings, which help to stretch the channel, and by the axial direction of its axis, which prevents the attached rotator from contributing to the stopping action.

The synthesis of chiral fluorinated 4-alkyl-4′-[(4-alkylphenyl) ethynyl]biphenyls

We have designed, synthesized, and evaluated the physical properties of new fluorinated phenyltolane based chiral liquid crystal materials with 2-methylbutyl chains. This type of fluoro-substitution in chemical combination with a phenyltolane core brings a surprising improvement to the mesomorphic properties. The investigated compounds exhibit broad temperature ranges for the N* phase and very low melting points. All homologues exhibited Blue Phase. We have applied a Cu-catalyzed cross-coupling reaction between aryl Grignard reagents and alkyl bromides for the synthesis of the products.

NEW SIMPLE METHOD FOR OBTAINING 4-n-ALKYL-4 prime -CYANOBIPHENYLS.

A new method is described of obtaining 4-n-alkyl-4 prime -cyanobiphenyls from biphenyl. First biphenyl is acrylated and the resulting ketone is reduced in conditions of the Huang-Minlon reaction; next the obtained 4-n-alkylbiphenyl is converted to 4-n-alkyl-4 prime -iodobiphenyl which readily reacts with copper cyanide giving the required nitrile with a good yield.
