Abstract
In this work, we studied the discotic liquid crystals (DLCs) of dibenzo[a,c]phenazine at the liquid-solid interface using scanning tunnelling microscopy/spectroscopy, by which we show how to tailor the DLC assemblies and in turn their electron-transfer efficiency. This study presents an alternative method for phase control and electronic measurements for DLCs, especially at the microscopic level.
