In this research, a novel nano-sized cube-shaped magnetic ionic liquid based on caffeine was synthesized and characterized by various spectroscopic and analytical techniques including Fourier transform infrared spectroscopy, Raman spectroscopy, proton NMR (1H NMR), carbon-13 NMR (13C NMR), mass spectroscopy, thermal gravimetric analysis/differential thermal gravimetric analysis, elemental analysis, inductively coupled plasma analysis, X-ray diffraction, energy dispersive X-ray analysis, field emission scanning electron microscopy, and vibrating sample magnetometer. The nano-magnetic IL exhibited eminent catalytic activity in the synthesis of various xanthenes under solvent-free conditions.
