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.
本文描述了一种以薄膜形式存在的材料,其中包含具有公式I的化合物,其呈定向排列,不显示点对称性,其中X为.dbd.CH--或.dbd.N--,R.sup.1为C.sub.12-C.sub.30-烷基,R.sup.2为氢或C.sub.1-C.sub.30-烷基,R.sup.3为--NO.sub.2,--CN,--CF.sub.3,--COCF.sub.3,--SO.sub.2 CH.sub.3或--SO.sub.2 CF.sub.3,R.sup.4为氢或与R.sup.3相同方式定义,R.sup.5为氢或--NR.sup.6R.sup.7,R.sup.6和R.sup.7独立地为氢或C.sub.1-C.sub.30-烷基,也可以是任何烷基部分氟化或全氟化。公式I的化合物可以排列在Langmuir-Blodgett层系统中。这种系统可以用于制造光电元件。
