Ordered π-conjugated polymer backbone in amorphous blend for high efficiency nonfullerene organic photovoltaics

open access: yesCommunications Materials, 2023
In π-conjugated polymers, the amorphous region absent from π–π stacking order typically limits polymer functions compared to the crystalline region with high π–π stacking order.

Coupling of iron phthalocyanine at carbon defect site via π-π stacking for enhanced oxygen reduction reaction [PDF]

open access: yes, 2021
The intrinsic activity of transition metal catalytic centers for oxygen reduction reaction (ORR) depends heavily on its electronic structure, which with an electron-rich environment will boost the ORR performance.

π-Stacking Stopper-Macrocycle Stabilized Dynamically Interlocked [2]Rotaxanes

open access: yesMolecules, 2021
The synthesis of mechanically interlocked molecules is valuable due to their unique topologies. With π-stacking intercomponent interaction, e.g., phenanthroline and anthracene, novel [2]rotaxanes have been synthesized by dynamic imine clipping reaction ...
