Understanding how to control nanostructures in organic molecules can boost their performance in devices like organic solar cells and transistors. In order to achieve hierarchically ordered nanostructures, phase separation and supramolecular forces have been used in block copolymers (BCPs) and liquid crystals (LCs) respectively.

Another innovative approach involves block molecules with organic components attached to oligodimethylsiloxane (oDMS). This method creates nanoscale ordering through directional interactions and phase separation. In this thesis, the design of block molecules has been studied in order to utilize oDMS's immiscibility with many organic molecules to obtain well-defined nanostructures with efficient energy transport between molecules. Furthermore, we showcase the improved properties of these block molecules, demonstrating their effectiveness in both light upconversion systems and energy transport.
