| Abstract: | A synthesis strategy for low molecular weight organogelators using the ureidopyrimidinone (UPy) group is reported. The prepared gelators showed robust thermal reversible gelation abilities in various solvents, including dimethyl sulfoxide. The morphology of the dried gels was determined using scanning electron microscopy, revealing a macroscopic porous structure of the gels. Rheology was performed to determine storage (G′) and loss modulus (G″) confirming network gel structures. |
