ABSTRACT
The sensing behavior of 2,5-thienylene-bridged tetrakis(2,6-dichlorophenyl)-[26]hexaphyrin (2) towards various metal ions and anions were investigated by UV-vis and fluorescence spectroscopies. Using this strapped hexaphyrin (2), the molecular sensor displayed highly selective and sensitive colorimetric responses to Cu2+ and Hg2+ in MeOH/THF. The spectral changes are distinctive enough in the visible region of the spectrum to enable naked-eye detection. The detection limits of Cu2+ and Hg2+ using this chemo-sensor in a mixed MeOH/THF solution were 1.978 and 1.283â
µM, respectively, and 1.052â
µM for F- in dichloromethane. Chemosensor 2,5-thienylene strapped [26]hexaphyrin (2) shows absorption responses both a 1 1 molecular ratio for 2 interacting with Cu2+ and Hg2+ and a 1 2 ratio between 2 and F- ions.
