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. The molecular sensor using this strapped hexaphyrin (2) 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‐sen… Show more
