英文摘要： Molecular switches can be used as basic unit in future logic and storage circuits, which become the hot topic and front research area in material science and technology. It is of great scientific significance and application value to realize molecular switch with switchable chirality and ferroelectricity in life science and information storage areas. This project is carried out on investigating the proportions of trans- and cis-conforms of bi-1,3,4-oxadiazole derivatives in different conditions to develop a new type of organic molecules with switchable functions.It is expected to build chiral and ferro/antiferoelectric supramolecular structures based bi-1,3,4-oxadiazole derivatives by modulating their molecular conformations, and get the informations of corresponding structures, such as XRD spectra, emission spectra, absorption spectra, polarizability, dielectric constants, electron mobilities.This project is aimed at realizing a novel type of organic electronic devices with electric field or light induced switchable chirality and ferroelectricity based bi-1,3,4-oxadiazole derivatives,and providing materials,theories and preparation technologies for molecular switch with electric field or light induced switchable chirality and ferroelectricity.
