The investigation of cooperative binding between p-sulfonatocalix[6]arene and fluorescein with transition metal ions by spectrometrically

The ternary complexes are formed by self-assembly through cooperative hydrogen bonding between p -SCX6-FL and M 2+ through water molecule which is reinforced by columbic and electrostatic interactions. The binding efficiency of Cu 2+ and Zn 2+ is observed at a greater extent than Co 2+ and Ni 2+ . F...

Description
Summary:The ternary complexes are formed by self-assembly through cooperative hydrogen bonding between p -SCX6-FL and M 2+ through water molecule which is reinforced by columbic and electrostatic interactions. The binding efficiency of Cu 2+ and Zn 2+ is observed at a greater extent than Co 2+ and Ni 2+ . Furthermore, the kinetic study of p -SCX6-FL-Cu 2+ and Zn 2+ reveals that the process of complexation is slower than the binary system (FL+ p- SCX6). Graphic abstract Synopsis. Herein we report the systematic complexation study of ternary model i.e., p -SCX6-FL-M 2+ by IR, NMR and UV-Visible and florescence technique.
