- 27 - Abstract of the Disclosure: A layer element comprises a base having a hydrophobic surface and, applied on this, one or more solid, thin, ordered layers of defined uni- form and regular structure, in particular monolayers or multilayers, having a uniform orientation of the layer- forming molecules in one direction. The said layers are formed from a metallomacrocyclic polymer which is fusible and/or soluble in an organic, water-immiscible solvent and is of the general formula [M(Pcyc)O]n, where M is Si, Ge or Sn, (Pcyc) is a complex-forming centrosymmetric poly- cyclic ring system, in particular a phthalocyanine ring system having hydrophobic substituents, and n is the mean degree of polymerization and is equal to or greater than 3. The novel layer elements can advantageously be pro- duced by the Langmuir-Blodgett technique, in which a solid- like monolayer Produced on a water surface from the metallo- macrocyclic polymers is transferred to a substrate having a hydrophobic surface by immersion and withdrawal of the said substrate. The layer elements according to the in- vention can be used, for example, as optical filters, eg. grey filters, interference filters or polarization fil- ters, in electrochemistry and the electrical industry, for example as electrodes, sensors, catalysts etc., as photosensitive elements for electrophotography, and for many other applications.
