摘要:
A material in the form of a film is described which contains, in an orientated arrangement which does not display point symmetry, compounds of formula I ##STR1## wherein X is .dbd.CH-- or .dbd.N--, R.sup.1 is C.sub.12 -C.sub.30 -alkyl, R.sup.2 is hydrogen or C.sub.1 -C.sub.30 -alkyl, R.sup.3 is --NO.sub.2, --CN, --CF.sub.3, --COCF.sub.3, --SO.sub.2 CH.sub.3 or --SO.sub.2 CF.sub.3, R.sup.4 is hydrogen or is defined in the same way as R.sup.3, R.sup.5 is hydrogen or --NR.sup.6 R.sup.7 and R.sup.6 and R.sup.7 independently of one another are hydrogen or C.sub.1 -C.sub.30 -alkyl, it also being possible for any of the alkyl radicals to be partially fluorinated or perfluorinated.The compounds of formula I can be arranged in Langmuir-Blodgett layer systems. Such systems can be used for example for the manufacture of opto-electronic units.
