Carbazole-Derived Amphiphile-Based AIEgen: Detection of Nitro-Antibiotics and Water-Repelling Surfaces

We have designed three amphiphilic substituted urea compounds
with
varying chain lengths. These hydrophobic amphiphiles displayed aggregation-induced
emission on solvent switching. The aggregates were further detailed
by microscopy. The hydrophobicity of these AIEgens has been used to
create water-repelling fluorescent surfaces. The AIEgen via the photoinduced
electron transfer-mediated mechanism has been applied in the detection
of nitroantibiotics. The analytical utility of the AIEgen is being
demonstrated concerning the detection of nitroantibiotics in biofluids.
