Abstract：The Schiff base’s reduced product N,N-bis(4-methoxybenzyl) ethane-1,2-diamine, which was used as a receptor L, was designed and synthesized for the first time in the present article. It was found that Cu2+ and Fe3+ could quench L in fluorescence observably and Zn2+ and Cd2+ could enhance L remarkably. So the two pair metal cation could set up “OR” logical gate relation with the receptor molecule L, then a logical recognition system be formed. The data of resolved ZnL’s single crystal indicated that ZnL belonged to monoclinic (CCDC No.747994). Integrated spectrum instrument was used to characterize the structure of its alike series of complex compound. According to ZnL’s excellent fluorescence character and the ability to exchange with contiguous metal cation, Zn2+/ZnL/Co2+, Zn2+/ZnL/Ni2+ fluorescent molecule switch was designed. It is hoped that the work above could be positive for the development of molecule computer, bio-intellectualized inspection technology (therapy) and instrument.
