文摘
- •
A novel rhodamine-2-chloronicotinaldehyde (R6CN) chemosensor was designed and synthesized in high yield.
- •
Rhodamine-2-chloronicotinaldehyde (R6CN) exhibits very high selectivity toward Al3+ ions and reversible “turn-off” fluorescence was achieved using the azide (N3−) anion.
- •
The complex between the chemosensor R6CN and Al3+ was found to have a 1:1 ratio by titration.
- •
The structure of the R6CN-Al3+ complex was determined using 1H NMR and FT-IR titration and molecular modeling studies.
- •
R6CN was mixed with PEGDMA polymer for chemosensing the Al3+ ion with reversibility by N3− ion.
