Pattering of luminescent materials is an important issue in the fabrication of various display devices. While vapor deposition through fine masks is the method of choice in manufacturing pixels for state-of-the-art organic light-emitting diodes (OLEDs), the method is limited to small organic molecules which could be sublimed at practical temperature and pressure ranges. In order to pattern non-vaporizable luminescent materials such as quantum dots (QDs.), one possible alternative is utilize surfaces pre-patterned with orthogonal anchoring groups which could selectively recognize complementary functional groups on the ligands of QDs with different colors. We herein report two orthogonal hydrophobic interactions, one involving fluorous interaction and the other involving arene-arene interactions, which could be exploited in such approach. Synthesis of thiol ligands terminated with desired functional groups, surface functionalization of substrates, and deposition methods are discussed. |
