摘要：
Two new macrocyclic systems (L-1, L-2) containing two emissive naphthalene were synthesized and characterized. The macrocycles were studied by NMR, C-13 NMR, COSY, HMQC, DEPT. microanalysis and mass spectroscopy. The influence of metal cations Na+, Cr3+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, and Hg2+ on the spectroscopic properties of the macrocyclic systems in acetonitrile/DMF 9:1 (v/v) mixtures were investigated by means of absorption and emission spectrophotometry. The macrocycle L-1 was found to be as an effective fluorescence sensor for Zn2+ ions. Zn2+ and Cd2+ ions show the most effects on the fluorescence intensity of L-2. C) 2012 Elsevier B.V.
