Side-Chain Supramolecular Polymers Employing Conformer Independent Triple Hydrogen Bonding Arrays
نویسندگان
چکیده
Derivatives of thymine have been extensively used to promote supramolecular materials assembly. Such derivatives can be synthetically challenging to access and may be susceptible to degradation. The current article uses a conformer-independent acceptor-donor-acceptor array (ureidopyrimidine) which forms moderate affinity interactions with diamidopyridine derivatives to effect supramolecular blend formation between polystyrene and poly(methyl methacrylate) polymers obtained by RAFT which have been functionalized with the hydrogen bonding motifs.

Chiral Solvation Induced Supramolecular Chiral Assembly of Achiral Polymers
To date, liquid crystal chirality, mechanophysical chirality, circularly polarized photon chirality, gelation and chiral solvation are all feasible candidates to generate optically active polymers and supramolecular chirality when employing achiral molecules as start‐ ing substances. Among this, chiral‐solvation‐induced chirality is one of the dominant methods for construction of chirality from...
متن کاملHydrogen Bonding Modules for Use in Supramolecular Polymers
Nature utilizes a wide range of noncovalent interactions to maintain the well-defined, three-dimensional structure of key biomacromolecules, such as proteins, DNA, and RNA. Because their discrete structures are the key to their biomacromolecular function, noncovalent interactions truly underpin all biological complexity and function and, thus, life itself. Supramolecular polymer chemistry takes...

Supramolecular polymers are a class of materials characterized by a repetition of monomer units held together by non-covalent forces such as metal coordination, π–π interactions and hydrogen bonding1–4. Compared with their covalent counterparts the unique properties of these polymers have attracted considerable attention, for instance, the self-healing ability that arises from the thermodynamic...
متن کاملHydrogen bonding: Attractive arrays.
hydrogen bonding is considered by many to be the ‘master key’ of molecular recognition — owing to its relatively predictable strength and directionality — and plays a major role in the assembly of diverse non-covalent assemblies1. Consequently, the study and exploitation of hydrogen bonds has been central to the development of modern supramolecular chemistry. In particular, numerous applied set...
