Two novel carborane-based benzimidazolium fluorescent probes 4a and 4b were synthesized using 1,2-bis(4-benzylbromophenyl)-o-carborane as starting materials. The structures were characterized by IR, 1H NMR, 13C NMR, 11B NMR and ESI-MS, and the recognition properties of probes 4a and 4b for nucleotides were studied by fluorescence and ultraviolet spectroscopy. The results of fluorescence titration showed that probes 4a and 4b could achieve on-off response to uridine monophosphate (UMP), and had good selectivity and sensitivity. The detection limit of probe 4b for UMP could reach 3.41×10–8 mol/L. The recognition mechanism of the probe 4b was studied by Jobʼs curve and 1H NMR titration.

Key words: carborane, benzimidazole, recognition, fluorescence quenching, uridine monophosphate
