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.

The present invention relates to a fluorine-bridged associate consisting of an oligomer or polymer containing fluorine radicals which are bonded to the oligomer or polymer backbone, and up to three types of functional units in the backbone which differ with respect to function and are selected from the group consisting of a hole-transport and/or hole-injection unit, an electron-transport and/or electron-injection unit and an emitter unit, and one to three types of compounds containing a fluorine radical which differ with respect to function and are selected from a hole-transport and/or hole-injection unit, an electron-transport and/or electron-injection unit and an emitter unit, and to an opto-electronic device in which the fluorine-bridged associate is employed.
