A novel intramolecular fluorescence resonance energy transfer (FRET) and photo-induced electron transfer (PET) based dendritic compound PDI-BODIPY has been developed: Tetra-boron-dipyrrin (BODIPY) attached perylene bisimide by click chemistry. Compound PDI-BODIPY as a fluorescence probe for rapid, selective, and sensitive determination of Hg(II) ions has 98% of high energy transfer efficiency. The dissociation constant (K-d) of the probe PDI-BODIPY with Hg2+ is 6.67 x 10(-12) M and the detection limit estimated from the titration results was 2 x 10(-8) M. Moreover, the imaging of Hg(II) ions in Hela cells further certified the potential value of the probe. (C) 2015 Elsevier B.V. All rights reserved.
