Figure 4. (A) The cooperative effect of intramolecular hydrogen-bonding in processing solution and intermolecular hydrogen-bonding on ITO surface leads to the formation of a molecular layer with both increased assembly density and enhanced assembly stability; (B) SAMs Structure of MeO-CzPACA and MeO-CzPA2 binding to ITO surfaces; (C) Schematic illustration of structure changes for SAMs with or without intermolecular hydrogen bonds after heating and cooling.
