文摘
- •
One-dimensional supramolecular organic nanofibers self-assembled by a carboxy-substituent perylene diimide (PDI) molecule through H-type π-π stacking and hydrogen bonding.
- •
PDI supramolecular nanofibers show highly efficient and stable photocatalytic activity under visible light.
- •
The highly efficient and stable activity was attributed to the well-defined H-type π-π stacking and the internal electric field caused by terminal carboxyl group.
- •
The electronic properties of PDI supramolecular nanofibers were elucidated.
