Fluorescence spectra of compounds 1–4 in the presence of 4-Nitrotoluene (Nitro 3). The concentration of 4-Nitrotoluene in DMSO is in the order of 0 M, 9.09 \(\times\) 10−5 M, 16.6 \(\times\) 10–5 M, 23.0 \(\times\) 10−5 M, 28.5 \(\times\) 10−5 M, and 33.3 \(\times\) 10−5 M for all (additions of 0 μL, 200 μL, 400 μL, 600 μL, 800 μL, and 1000 μL).
