Abstract
Non-centrosymmetric films are shown that exhibit pyroelectric and piezoelectric properties. The films, which comprise alternating layers of omega-tricosenoic acid and omega-tricosenoic amine of up to nine layers thick, and alternatively, layers of polymeric amphiphiles that utilize their liquid crystalline side chains to impose order on the lamiante structures, are useful in constructing devices for measuring temperature and pressure functions.
