Noncovalent interactions for enhancing organic electronic device function.

Organic electronic device performance is increasingly recognized as an emergent property governed by molecular organization. This review highlights how noncovalent interactions enable precise control over molecular packing and nanoscale morphology in organic semiconductors. The key concept is the structure-function relationship, demonstrating that supramolecular chemistry is a crucial factor in achieving programmable, multifunctional and highly efficient devices. As design rules continue to mature and understanding of supramolecular order deepens, these strategies are poised to play a central role in the development of next-generation organic electronic devices with enhanced efficiency, stability, and functional richness.
