| Abstract: | A luminescence‐sensing process based on coordination compound [H2N(CH3)2]3[Tb(dipic)3] was developed. It shows fast response (within 1 min), high selectivity, and is ultrasensitive to detect Fe3+ or Cr3+ in aqueous solution and living cells (KSV values are calculated to be 3.6×104 L mol?1 for Fe3+ and 1.9×104 L mol?1 for Cr3+). The whole recognition process has been witnessed through electrospray ionization mass spectrometry (ESI‐MS) analysis, and the ligand‐transfer‐induced luminescence‐quenching mechanism is interpreted. This work contributes to extend the potential applications of lanthanide coordination compounds (LnCCs) in the fields of biological and environmental technologies. |
