A newly designed stiff-stilbene functionalized biscalix[4]arene in its cis form Z-1 could be near-quantitatively photoswitched to the trans-isomer E-1 under irradiation of 385 nm UV light. The trans-biscalix[4]arene E-1 was found to be a supergelator in nonpolar organic solvents, e.g., cyclohexane, hexane, pentane, and ether, with critical gelation concentrations as low as 0.2, 0.5, 0.5, and 0.4% w/v
