    • To investigate the effect of π-π stacking interactions on gelation ability, bisurea 8 lacking OPV moieties was also subjected to a gelation test. Compound 8 only gelated n-hexane (minimum gelation concentration = 0.332 wt%), n-decane (0.160wt%), and dioxane (0.706 wt%). This result clearly shows the significant contribution of π-π stacking interactions on gelation. figure presented
