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.
本发明涉及新型化合物,适用于制备具有压电、热释电性能和提供二次谐波生成的多层薄膜。这些新型化合物是两性的,可以通过在基底上沉积它们来制备相同极性的单层和多层薄膜。当这样的基底是固体支撑时,可以获得极性Z型Langmuir-Blodgett薄膜。在这些化合物的薄膜在空气/水界面压缩时,形成稳定的Langmuir单层。
