Host‐enhanced π–π interaction based on anthracene derivatives and cucurbit[8]uril can be used as the driving force for constructing water‐soluble supramolecular polymers. For this purpose, two anthracene moieties were encapsulated into one cucurbit[8]uril cavity, forming a ternary complex. After encapsulation in the host, the distance between the two anthracene moieties was shortened, and the π–π interaction between them was enhanced significantly. To realize supramolecular polymerization, a bifunctional monomer consisting of two anthracene moieties and a short linker in between was carefully designed. Cyclization was avoided in this way. Thus, host‐enhanced π–π interaction can function as a new driving force for supramolecular polymerization.
