(A) Tauc plot of energy (hυ) against (αhυ)2 for the CTC of SEL with DDQ in acetonitrile. (B) Benesi-Hildebrand plot for the formation of CTC of SEL with DDQ. In panel (B), linear fitting equation and its determination coefficient (R2) are provided on the plot. [SEL], [DDQ], and A, are the molar concentration of SIT, molar concentration of DDQ, and absorbance of the CTC, respectively
