  Rhodamine-based ‘turn-on’ fluorescent probe for Cu(II) and its fluorescence imaging in living cells

  摘要：

  A novel rhodamine spirolactam derivative 3',6'-Bis(diethylamino)-2-(2-hydroxyethylamino) spiro[iso-indoline-1,9'-xanthen]-3-one (RO1) was synthesized, and characterized by high-resolution mass spectrometry (HRMS), X-ray crystallography, Infrared spectroscopy (IR), and H-1 NMR and C-13 NMR spectroscopy. RO1 exhibited highly sensitive and exclusively selective fluorescence response toward Cu2+ over other metal ions with a detection limit of 0.56 ppb in mixed aqueous solution. The fluorescence was pH-independent in the wide range pH 3.1-11.6. The turn-on fluorescence enhancement of the probe is based on Cu2+ induced ring-opening mechanism of the rhodamine spirolactam. Moreover, by means of fluorescence microscopy experiments, it was demonstrated that RO1 could monitor trace Cu2+ changes by live cell imaging. (C) 2013 Elsevier Ltd. All rights reserved.

  hydrazide (ARBHE) was synthesized from N-hydroxyl ethyl-N′-rhodamine hydrazide (RBHE) and acryloyl chloride (Ac) in the presence of triethylamine in dry dichloromethane (CH2Cl2) at room temperature. The synthesized ARBHE was identified by FTIR, 1H NMR spectra and elementary analysis. Copolymer poly(AM-ARBHE) of ARBHE and AM was synthesized with thermal initiator by free radical precipitation polymerization
