Luminescent Mo?bius Strip of a Flexible Halogen-Bonded Cocrystal Evolved from Ring and Helix

Luminescent Mo''bius strip microstructures have been created for the first time based on flexible organic single crystals via a template-free solution self-assembly. We herein demonstrated a rationally designed morphological evolution toward Mo''bius strips from rings and helixes. Our findings lay the foundation for the future construction of complex matters with predetermined morphologies and functions from crystal systems.
