In this presentation, a variety of examples of the self-assembled nanostructures are demonstrated, based on BCPs as well as supramolecular assembly of end-functionalized polymers, forming BCP-like supramolecules for displays, sensors and energy harvesters. First, we demonstrate an ink-jet printable and re-writable BCP structural color (SC) display that can be quickly written and erased. We also demonstrate that BCP SC is used as a stretchable strain capacitive sensor which can visualize the strain. Second, a surface switchable triboelectric nanogenerator is demonstrated with an alkali metal-bound nanoporous film arising from supra-molecularly assembled end-functionalized polymers. Finally, we show that the BCP assembly allows for fabricating nanostructured organic-inorganic hybrid perovskite films with significantly enhanced photoluminescence with high resistance to humidity and heat, enabling a facile control of color coordinates by color conversion layers in blue-emitting devices.
