| Popis: | We report a versatile functionalization and pattering technique that permits multicomponent pattern-specific modification of indium tin oxide (ITO) with organic species. The method relies on a bilayered molecular system that simultaneously protects ITO from degradation and provides uniform chemical functionality suitable for further elaboration. Pattern-specific modification is achieved via specific reaction between functionality on an elastomeric stamp and functionality of cognate reactivity at the surface of a bilayered molecular substrate. We demonstrate that a single molecular system in a combination with different printing approaches can be used to immobilize multiple organic functionalities with exquisite spatial control on a single ITO surface. Our study provides the first general approach that permits patterning and functionalization of ITO with different molecules using a single set of printing conditions and materials. |
