Figure 2. Synthesis of the WCC.

Figure 2

(a) A schematic displaying the synthetic route to the WCC. (b) Simulated structure of the WCC. (c) Raman spectra of β-CAR and the WCC. (d) Fluorescence spectra of WP5 (150 μM) on addition of β-CAR in ethanol/water (excited at 268 nm) at room temperature. (e) The fluorescence intensity changes of WP5 at 653 nm. (f) Time-dependent ultraviolet–visible spectra showing the formation of the WCC, as indicated by the changes in the intensities of the peaks at 290 and 484 nm (20 min each). (g) Plot of absorbance intensity as a function of time (20 min each). (h) FT-IR spectra of WP5, β-CAR and the WCC.
