Abstract: The invention relates to novel compounds which are suited for the production of multilayer films which have piezoelectric, and pyroelectric properties, and which provide second harmonic generation. The novel compounds are amphiphilic and it is possible to prepare from same polar single-layer and multi-layer films by depositing them on a substrate. When such substrate is a solid support, polar Z-type Langmuir-Blodgett films are obtained. Upon compression of films of such compounds, at an air/water interface, stable Langmuir monolayers are formed.
