## Abstract A heterogeneous βnakedβeyeβ colorimetric and spectrophotometric cation sensor, SNTβ**1**, was prepared by immobilization of the azoβcoupled macrocyclic receptor **1** on a silica nanotube (SNT) via solβgel reaction. The optical sensing ability of SNTβ**1** was studied by addition of met
