Novel bolaamphiphiles consisting of a rigid biphenyl unit, two terminal polar 1,2-diol units and laterally attached (semi)perfluorinated chains have been synthesized via palladium-catalyzed cross coupling reactions as the key step. The thermotropic liquid

An efficient method for the preparation of perfluorooctylated aromatic and heteroaromatic compounds has been developed using photolysis of perfluoroazooctane (E)-1 upon 185 nm irradiation. The use of a two-phase system made up of a perfluorohexane solution of (E)-1 and a suitable aromatic compound has proved efficient for this reaction. The photolytic mechanism of (E)-1 upon 185 nm irradiation has also been investigated on the basis of quantum yield, light intensity dependence and UV-VIS spectra. It is shown that (E)-1 is photoisomerized by one photon absorption to the (Z)-isomer, with subsequent extrusion of nitrogen by a second photon absorption.
