An ‘off–on’ fluorescent chemosensor of selectivity to Cr3+ and its application to MCF-7 cells
摘要:
A 'switching-on' fluorescent chemosensor for the selective and sensitive signaling of intraceullar Cr3+ has been designed and synthesized exploiting the guest-induced prohibition of the photoinduced electron transfer process between naphthyridine moiety and 7,10-diphenylfluoranthene moiety, the system shows a Cr3+-selective chelation-enhanced fluorescence response not only in ethanol but in cell.

A fluorescent color/intensity changed chemosensor for Fe3+ by photo-induced electron transfer (PET) inhibition of fluoranthene derivative
摘要:
A fluorescent color/intensity changed fluoranthene derivative chemosensor for Fe3+ has been prepared and confirmed by H-1-NMR, C-13-NMR, HRMS, and crystal data, which displays a high selectivity and antidisturbance for Fe3+ among environmentally and biologically relevant metal ions. Fluorescence studies show that fluorescent emission peak blue shifts about 100 nm with fluorescent intensity enhancing 75-fold, indicating a Fe3+-selective dual-emission behavior. Further study demonstrates the detection limit on fluorescence response of the sensor to Fe3+ is down to 10(-7) M range. The fluorescence signals of chemosensor can be restored with o-phenanthroline, showing the binding of chemosensor and Fe3+ is really chemically reversible. (C) 2011 Elsevier Ltd. All rights reserved.
