Abstract

original image

A sequential deprotection and immobilization procedure was enabled by the synthesis of two thiophene–thiazole diblock oligomers with two different thiol protection groups. Investigation of the I/V behaviors of these diblock molecules between two gold electrodes (see picture) showed that the rectifying direction was controlled by their orientation between the electrodes.
