Synthesis and Self‐Assembly of Hydrogen‐Bonded Supramolecular Polymers

Facile Construction of Metallo-supramolecular Poly(3-hexylthiophene)-block-Poly(ethylene oxide) Diblock Copolymers via Complementary Coordination and Their Self-Assembled Nanostructures

“…Although these methods have been successfully applied in the preparation of well-defined rod–coil block copolymers, development of facile synthetic strategies to avoid tedious purification steps still remains a formidable challenge. In contrast to covalent connectivity, supramolecular polymers consist of monomers or segments held together by noncovalent interactions such as metal–ligand coordination, π–π stacking, host–guest interaction, and hydrogen bonding . The supramolecular methodology provides an alternative way to readily produce a wide variety of block copolymers possessing dynamic functions. , Despite the weak bonding strengths, the recent advances have manifested that supramolecular block copolymers constructed through complementary molecular building blocks could preserve the structural integrity and afford well-ordered, self-assembled nanostructures …”

Facile preparation of supramolecular (ABAC)n multiblock copolymers from Hamilton wedge and barbiturate-functionalized RAFT agents

“…With the spread and expanding interest in supramolecular chemistry, there has been a growing realization of supramolecular multiblock copolymers over recent decades. [1][2][3][4][5][6][7][8][9][10] So far, mainly two types of noncovalent interactions, i.e. hydrogen bonding, [11][12][13][14][15] and metal-ligand coordination, [16][17][18] have been studied for creating well-dened supramolecular multiblock copolymers.…”

Micelles Protect Intact Metallo-supramolecular Block Copolymer Complexes from Solution to Gas Phase during Electrospray Ionization

“…Rod–coil diblock copolymers, comprising rigid macromolecules covalently connected with flexible counterparts, have drawn tremendous research interest because of their unique self-assembled morphologies both in solution and in the solid state. − In the midst of various rod segments, poly­(3-hexylthiophene) (P3HT) has aroused particular attention due to its wide applicability, but tedious synthetic procedures have impeded development of diversified polymer architectures. In contrast to irreversible covalent binding, supramolecular polymerization and coupling methods through reversible noncovalent interactions, such as metal–coordination bonds, − aromatic interactions, − host–guest interactions, − and hydrogen bonding, − not only offer a facile access to preparation of sophisticated topologies but also endow the materials with dynamic functions. − Nevertheless, the structural characterization of supramolecular polymers by size-exclusion chromatography (SEC) or mass spectrometry (MS) commonly encounters difficulties because the weak interactions are unsustainable in such harsh analytical environments. , Hence, developing new characterization techniques for molecular weight measurements of intact supramolecular polymers is still an urgent and challenging task.…”
