| Summary: | 碩士 === 靜宜大學 === 應用化學系 === 105 === In this thesis, a series of azine derivatives were designed and synthesized as for metal ion chemosensors. UV-Vis spectra showed that 1,2-di(N,N-dimethylaminobenzylidene)hydrazine (3) in acetonitrile and dichloromethane had interactions with silver, chromium, ferrous, ferric, and copper ions. The interaction of azine 3 with ferric ions was most pronounced. Symmetric azine 7 and asymmetric azine 8 showed interactions with copper, cobalt, cadmium, nickel, lead, and zinc ions.
At pH 8, both asymmetric azine 8 and symmetric azine 2, 2-hydroxyphenyl azine, exhibited weak orange fluorescence at high concentrations and weak green fluorescence at low concentrations. At the same condition, both symmetric azine 8 and symmetric azine 2 demonstrated strong AIEE phenomena, namely, no fluorescence in DMSO/water 9:1, weak green fluorescence in fluorescence in DMSO/water 1:1, and strong green fluorescence in DMSO/water 1:9.
