Abstract: The synthesis of a new chromogenic N,N′-phenyltetrazole receptor is reported here. The cationbinding properties of this receptor in solution were investigated by naked-eye colour change, electrochemical methods and UV-Vis spectroscopy in various solvents (CH₃CN, dimethylsulphoxide (DMSO), DMSO/H₂O, CH₃CN/H₂O and CH₃CN/MeOH). In addition, the receptor was used as a sensing material in ion-selective membrane electrodes. The selectivity and sensitivity of these electrodes towards alkali, alkali-earth, transition and heavy metal cations in aqueous solution were tested. The relation between the carrier structure and membrane plasticisers was investigated.

Keywords: UV-Vis spectroscopy – bis-tetrazoles – ionophores – copper sensor – naked-eye detection
