Abstract
An oligo(dimethylsiloxane) carrying ionophorous calix[4]arene moieties at the side chain was synthesized as a Na+ neutral carrier for highly durable silicone-rubber membranes of ion-selective electrodes by reac ting calix[4]arene tetraallyl ester with an oligo(methylsiloxane). Thi s medium-molecular-weight calix[il]arene ionophore alleviated the draw back of chemically-modified calixarene-based silicone-rubber membranes , such as a high membrane impedance and a slow electrode response.
