摘要: Abstract A novel fluorescent sensor N-((2-hydroxynaphthalen-1-yl)methylene)-1H-1,2,4-triazole-3-carbohydrazide (NTA), based on triazole was synthesized in two facile steps, characterized systematically and used as a turn-on for both Al3+ F−. The fluorescence spectra changes showed that NTA is highly selective over other metal ions MeCN–H2O solution. receptor could also sense F− selectively MeCN. complexation properties of with were observed by 1H NMR titration experiments.
