Fluorescent gelators containing stilbene segments were synthesized, and their gelation abilities were studied. Fibrous xerogel films were prepared from the gels on quartz plates, and their abilities to detect explosives were evaluated by the fluorescence quenching of the xerogel films upon exposure to saturated TNT or RDX vapor. The morphologies of the xerogel films were studied by TEM and DFM. The xerogel films that showed effective fluorescence quenching were found to have 3D fibrous networks with widths of several tens of nanometers and entangled fibrous aggregates with very uneven surfaces. The mechanism for detecting TNT was discussed from the viewpoint of HOMO and LUMO levels.
