Spontaneous Supramolecular Polymerization Driven by Discrete Platinum Metallacycle-Based Host–Guest Complexation

Considerable
progress in platinum metalla­cycle-based supra­molecular
polymerization has promoted the fabrication and application of supra­molecular
materials. However, despite recent advances, supra­molecular
polymers constructed through platinum metalla­cycle-based host–guest
complexation remain rare because of the dynamics of platinum metalla­cycles.
Here, we achieve linear supra­molecular polymerization via platinum
metalla­cycle-based host–guest complexation by following
the design rule of suppressing the dynamics of the metalla­cycles.
The establishment of the platinum metalla­cycle-based host–guest
system and the realization of this type of supra­molecular polymerization
are expected to open opportunities for platinum metalla­cycle-based
functional materials.
