“…Among these interactions, orthogonal self-assembly represents a unique process in which different kind of interactions do not interfere with each other during the self-assembly process . Particularly, supramolecular polymers that are constructed via orthogonal noncovalent interactions have been used to produce smart materials with enhanced stimuli responsiveness and also to fabricate hierarchically ordered systems. − Responsive behavior of these materials is provided by means of dynamic bonds based on various intermolecular reversible interactions such as π–π stacking, hydrophobic interactions, metal–ligand coordination, hydrogen bonding, anion recognition, and host–guest interactions. ,− …”

Supramolecular alternating polymers (SAPs) were constructed based on orthogonal interactions between an alkylnitrile-tethered calix [4]pyrrole and two different carboxylatefunctionalized pillar[5]arene monomers possessing different chain lengths. Concurrent anion complexation and host−guest interactions were utilized by means of calix[4]pyrrole-and pillar[5]arene-based molecular recognitions. Characterization and multiresponsive behaviors of the resulting SAPs were characterized by means of a series of analyses, including various nuclear magnetic resonance techniques, viscosity measurements, and scanning electron microscopy. The resulting polymers were also applied to the fabrication of hierarchical materials with different dimensionalities. These materials include spherical aggregates with zero-dimensionality, fibers with one-dimensionality, two-dimensional microporous films, and finally three-dimensional materials. Current work represents the first example of SAPs based on calix[4]pyrrole and pillar [5]arene molecular recognition and is expected to be useful for designing and preparation of advanced, multicomponent synthetic self-assembled systems.

Supramolecular combination therapy adopts supramolecular materials to design intelligent drug delivery systems with different strategies for cancer treatments. Thereinto, macrocyclic supramolecular materials play a crucial role in encapsulating anticancer drugs to improve anticancer efficiency and decrease toxicity towards normal tissue by host–guest interaction. In general, chemotherapy is still common therapy for solid tumors in clinics. However, supramolecular combination therapy can overcome the limitations of the traditional single-drug chemotherapy in the laboratory findings. In this review, we summarized the combination chemotherapy, photothermal chemotherapy, and gene chemotherapy based on macrocyclic supramolecular materials. Finally, the application prospects in supramolecular combination therapy are discussed.
