Abstract

A new chemosensor S8 compound from the flavon group that has been successfully synthesized. Test its ability as a chemosensor for F^- anion, providing positive results that it can recognize F^- anion with response to an increase in fluorescent solution. Titration of S8 solution in DMSO solvents was carried out with F^- anion at various concentrations and then measurements were made on fluorometry instruments. The fluorescent titration emission spectrum shows that the S8-FË‰ host-guest interaction quantitatively in the form of LOD and k_ass. LOD and K_ass values are 6.43 Ã— 10Ë‰⁴ M and 2 Ã— 10⁶ MË‰¹, respectively.
