A series of fluoroaryl 1,3,4-oxadiazole derivatives I [R = Et, hexyl, decyl] substituted with different para terminal ethers were synthesized using SNAr chem. to afford fluorescent and thermally reversible low mol. weight organogelators (LMWOs). SNAr was used to synthesize these highly fluorinated organogelators in high purity and good yields starting from pentafluorobenzoic acid and 4′-hydroxy-4-biphenylcarbonitrile. These fluorinated 1,3,4-oxadiazole derivatives were characterized by elemental anal., FTIR and 1H, 13C and 19F NMR spectroscopy. The photophys. properties of those organogelators were described. Both UV-visible absorption and fluorescence spectral profiles displayed a solvatochromic and solvatofluorochromic properties. The absorption maxima for the developed organogelators were monitored in the range of 260-289 nm, whereas the emission maxima were monitored in the range of 278-305 nm. The best gelation properties were monitored for the compound I [R = hexyl] in different solvents with critical gel concentrations in the range of 1.86-5.07 mM. The self-assembly process was monitored to occur via van der Waals forces and π-π stacks to result in gelation of solvents. Scanning electron microscope (SEM) demonstrated nanofiber-like structures (350-550 nm). The thermal stability of the compound I [R = hexyl] was monitored at 48°C. Both cytotoxicity and antimicrobial activity of the produced fluoroaryl 1,3,4-oxadiazole derivatives were explored to verify their potential use for biomedical applications, such as drug delivery and bioimaging.
