A new gelator of urea‐containing triazine derivatives was synthesized, and its gelation potential was examined in different organic solvents. The compound was found to form organogels with a variety of organic solvents such as decalin and other solvents. The resulting thermo‐reversible gel was characterized by using the dropping ball method and a number of other instruments. The melting temperature of the gels in decalin and DMSO increased with the gelator concentrations. Intermolecular hydrogen bonding of gelation was observed with a FT‐IR spectrometer. Temperature‐dependent UV‐Vis and fluorescence analysis revealed that the organogels displayed the H‐type aggregation in decalin and the J‐type aggregation in DMSO. The morphological features of the gels in decalin and DMSO were studied by applying atomic force microscopy (AFM), and the morphological features demonstrated that there were different aggregations in different solvents.
