Novel optical/electrochemical selective 1,2,3-triazole ring-appended chemosensor for the Al3+ ion.
A chemosensor (1) bearing a 1,2,3-triazole ring spacer was synthesized for the selective detection of Al(3+) with respect to dual optical and electrochemical changing events. The addition of Al(3+) ions to 1 induced a significant change in fluorescence intensity, attributable to ICT and CHEF effects from the 1,2,3-triazole ring. The electrochemical behavior of 1 in the presence of the Al(3+) ion was significantly altered compared with those of the other metal cations tested.
