A Supramolecular Polymer Blend Containing Two Different Supramolecular Polymers through Self‐Sorting Organization of Two Heteroditopic Monomers

Abstract

Sorting itself out: A novel and modular supramolecular polymer blend was prepared by means of self‐sorting organization of two heteroditopic AB‐type monomers. By blending two different low‐molecular‐weight molecules, versatile and interesting micro‐ and macroscopic aggregates were prepared. This research provides a powerful strategy to prepare complex and highly ordered structures.

“…107 The monomer 67 also showed a blending property with other similar low molecular weight molecules to form micro-and macroscopic aggregates. 108 Instead of dibenzo [24]crown-8, benzo-21-crown-7 was also employed to generate a 3D supramolecular polymer network upon the addition of bisammonium salt to form [2]pseudorotaxane host/guest linkages. 109 The resulted dynamer presented dual thermal-and cation-responsive gel−sol transitions.…”

Self‐Sorting of Four Organic Molecules into a Heterowheel Polypseudorotaxane

“…The influence of the alkyl chains: To obtain further insight into the role of alkyl chains in viologens, we synthesized additional three viologen derivatives with different alkyl-chain lengths ( Figure 1); namely, N,N'-dibutyl-4,4'-bipyridinium (6), N,N'-dihexyl-4,4'-bipyridinium (7), and N,N'-didecyl-4,4'-bipyridinium (8), respectively. With the exception of viologens with shorter aliphatic N-substituents (n 3), compounds 2, 6-8 or other viologens with longer aliphatic Nsubstituents favor the formation of complex with 1.…”

“…The appearance of the new absorption band should be attributed to CT interactions between the Np moiety of 1 and bipyridinium of viologen derivatives, whereas the difference of their strength is perhaps due to the stronger hydrophobic interaction between the longer alkyl chains and the cavity of CD (see the Supporting Information, Figure S19). When 1,3,CB[8] and one of viologen derivatives (6,7,2,8) were mixed in D 2 O solutions, the NMR experiments were performed in turn. These observations suggest that increasing the chain length of viologens can affect the formation of ternary complex of viologens, 3, and CB [8].…”

Catenation and encapsulation induce distinct reconstitutions within a dynamic library of mixed-ligand Zn4L6 cages

“…This approach has been used to identify protein inhibitors,6 design mixtures of compounds that self-sort into different host–guest complexes7 and to engineer separations of mixtures of molecules held together by dynamic covalent bonds 8. In some cases, the response of a DCL to a stimulus has led, through reconstitution of the system, to the promotion of library members that may otherwise not be observed 9…”
