摘要：

Based on a metal-template synthetic strategy, a new polyaza macrocycle bearing two anthracenyl fluorophores ligand, N,N'-bis[(anthracen-10-yl)methylene]-5,6,8,9,14,15,17,18-octahydrodibenzo[f,m][1,3,5,8,10,12]hexaazacyclotetradecine-7,16-diamine (L), was prepared and fully characterized. In the presence of Zn(II), L displayed remarkable chelation-enhanced fluorescence and can selectively respond to the presence of Zn(II) ion compared with other cations in HEPES-buffered aqueous methanol solutions. Results obtained from UV-Vis and fluorescence titrations indicated that L chelates to Zn(II) by forming a complex with a 1:1 molar ratio.
