Additionally, its behaviour in the presence of several ions (H+, Zn2+, Cd2+, Cu2+, Ni2+, Pb2+, Fe2+, Hg2+ and Al3+) was investigated in CH2Cl2. It was found that the absorption spectra of probe 1 shows no differences for all ions titrations except in the presence of H+ and Hg2+ where a new longer wavelength band becomes visible (inducing a colour change from yellow to orange and pink, respectively). In the emission, a blue-shift and an enhancement of the fluorescence of the probe for all metal ions was observed with the exception of Al3+ where no detectable changes could be observed. The probe was found to be selective for Hg2+ ion at low concentrations (till one equivalent).Elsevier2014-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/27907http://hdl.handle.net/10316/27907https://doi.org/10.1016/j.dyepig.2014.04.012engPINHEIRO, Daniela [et. al] - From yellow to pink using a fluorimetric and colorimetric pyrene derivative and mercury (II) ions.
