A Crown-Ether Loop-Derivatized Oligothiophene Doubly Attached on Gold Surface as Cation-Binding Switchable Molecular Junction
A crown‐ether dithiol quaterthiophene is synthesized and immobilized on gold surface by double covalent fixation. UV‐vis spectroscopy and cyclic voltammetry show that the corresponding dithioester precursor can complex Pb2+ in solution and that this property is maintained for monolayers of the dithi...

| description | A crown‐ether dithiol quaterthiophene is synthesized and immobilized on gold surface by double covalent fixation. UV‐vis spectroscopy and cyclic voltammetry show that the corresponding dithioester precursor can complex Pb2+ in solution and that this property is maintained for monolayers of the dithiol on gold. Current‐voltage measurements by eutectic GaIn drop contact on the monolayer show a significant increase (up to 1.6 × 103 times) of the current at low bias after Pb2+ complexation. |
