Numerical results show that the current through the closed-state system is larger than that through the open-state system under small bias, indicating the switching behavior is stable under small bias, and the photoswitchable performance can be improved by F-substituent significantly. %K 二芳烯, %K 分子开关, %K 取代 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=BA7668FDF732DED176918146F8DC7E30&yid=67289AFF6305E306&vid=11B4E5CC8CDD3201&iid=B31275AF3241DB2D&sid=64A7D9D26DF68B46&eid=858F8C9C69F21D66&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=37
