Novel luminescent organogelators based on nucleosides functionalized with carbazole ( UC8 , UC12 and UC16 ) were designed and synthesized. Their gelation ability was tested and it was found that both UC12 and UC16 could form stable organogels in toluene/petroleum ether. The UV/Vis absorption, fluorescence emission, and IR spectral changes during the gelation of UC12 proved that the self‐assembly was driven by hydrogen‐bonding. The morphology of the xerogel UC16 obtained from toluene/petroleum ether (v/v 1:1) displayed tough rod‐like microstructures, and 3D networks formed from numerous nanofibers were observed for the xerogel UC16 obtained from toluene/petroleum ether (v/v 2:1). It was interesting that the obtained organogels emitting blue light could be destroyed by the addition of F – , accompanied by a reduction of the emission intensity. Therefore, these organogels could be used as sensory materials to recognize F – .
