Self-Assembling Luminophores Form Nanotubes with Multidirectional Exciton Transport

Research
For many years, designing synthetic polymer systems has been inspired by the hierarchical self-assembly of folded proteins into functional nanostructures. However, extending folding-based design principles to small synthetic molecules has remained elusive. In particular, luminescent molecules with complex three-dimensional structures were considered difficult to assemble. Now, researchers from Japan demonstrate that such molecules can undergo folding-mediated self-assembly to form highly ordered nanotubes. These structures exhibit unique multidirectional energy transport, highlighting their potential for advanced optoelectronic applications.

A recent study shows that sterically demanding diphenylanthracene-based artificial π-luminophores can be programmed to self-fold and preorganize into highly ordered supramolecular nanotubes. This folding-mediated assembly guides directional π–π stacking and cooperative interactions, enabling the formation of stable curved architectures. Notably, the resulting nanotubes exhibit multidirectional exciton migration—both along the tube axis and around its circumference—revealing a new molecular design strategy for advanced optoelectronic materials.
