Interaction of Schiff base ligand with tin dioxide nanoparticles: Optical studies

• Optical studies of Schiff base (SB) ligand with semiconductor oxide NPs were studied.
• Weak interaction between BMTPMB and SnO2 NPs was observed.
• Scott plot was employed to determine the molar absorptivity of the SB-NPs system.

Interaction between 1,4 Bis ((2-Methyl) thio) Phenylamino methyl benzene (BMTPMB) Schiff base with tin dioxide nanoparticles (SnO2 NPs) of various concentrations in methanol have been studied using UV–Visible and Fluorescence spectroscopic techniques. The low value of Stern–Volmer quenching constant and non-linear plot of Benesi–Hildebrand equation suggests the less affinity of SnO2 NPs towards the adsorption of BMTPMB Schiff base. The Scott equation has been employed to determine molar absorptivity of the Schiff base-NPs system.
