Fluorescence and UV-Vis absorption spectra for the CA + [EMIM]N(CN)2 (a,c) and [EMIM]N(CN)2 alone (b,d) samples heated in a 90 W microwave oven for 4.5 min (a,b) and in an autoclave at 200 °C for 30 min (c) and 5.0 h (d). After the addition of 1.0 mL of H2O to the heated products, the product solutions of 0.2 μL for (a); 0.3 μL for (b); 2.0 μL for (c); and 15 μL for (d) were diluted with 3.0 mL of H2O to measure the spectra.
