“…S4 and S5 †) presented a distinctive peak at ∼157 ppm corresponding to imine carbon (-C]N), conrming the Tab-Dfp and Tta-Dfp formation. 41,43,45,[48][49][50] The carbon atoms of the phenyl, triazine, and pyridine groups are responsible for the signals at 120, 126, 130, 150, and 167 ppm respectively, conrming the Tta-Dfp's chemical structure. Similarly, the carbon atoms of the pyridine and phenyl rings of the Tab-Dfp structure are responsible for the signals at 147, 136, 126, 121, 114 ppm, con-rming the Tab-Dfp's chemical structure.…”
