RESUMEN
Controlling supramolecular polymerization is of fundamental importance to create advanced materials and devices. Here we show that the thermodynamic equilibrium of Gd3+-bearing supramolecular rod networks is shifted reversibly at room temperature in a static magnetic field of up to 2 T. Our approach opens opportunities to control the structure formation of other supramolecular or coordination polymers that contain paramagnetic ions.
RESUMEN
We demonstrate supramolecular pathway selection of a perylenediimide derivative in aqueous solution using chemically fueled redox reactions to control assembly/disassembly cycles. The number and frequency of cycles affect the nucleation and growth process, providing control over the size and internal order of the resulting self-assembled structures.
