In recent years, the field of supramolecular chemistry has progressed from rather simple non-covalent complexes of small molecules to increasingly complex and dynamic structures and materials. Also the interplay of supramolecular chemistry and polymer chemistry has witnessed exciting developments. The formation of supramolecular polymers by non-covalent interaction of monomers and the self-assembly of block-copolymers in solution and bulk are two prominent examples. This special issue of Polymers aims to highlight recent advances in the area of molecular recognition and folding of polymers, chirality and controlled growth of supramolecular polymers, smart polymersomes, stimulus-responsive and self-healing polymers, and more.

Title: Charge-Transfer Complexes Studied by Dynamic Force Spectroscopy

Abstract: In this manuscript, the strength and kinetics of two charge-transfer complexes, naphthol-methylviologen and pyrene-methylviologen, are studied using dynamic force spectroscopy. The dissociation rates indicate an enhanced stability of the pyrene-methylviologen complex, which agrees with its higher thermodynamic stability compared to naphthol-methylviologen complex.

Title: Metal Coordination and Organometallic Chemistry for Supramolecular Metal Containing Polymers and Nanomaterials

Abstract: Building on established supramolecular chemistry, metal coordination and organometallic chemistry have been widely investigated for their potential application in supramolecular polymers and nanostructures. Increasingly, literature has demonstrated that this is a promising approach for the synthesis of novel materials with functions derived from metal elements and their coordination structures. However, when systems involve multiple non-covalent interactions in addition to metal coordination, unique self-assembly behaviour and unexpected supramolecular strucutres are frequently discovered. Understanding the synergistic effects of non-covalent interactions for the designed synthesis of metal containing assemblies with high structure complexity is a key challenge at the forefront of the field. Recent reports are highlighted in this review in an attempt to illustrate the state of the art of the area and stress the importance to develop controlled chemistry for the synthesis of metal containing assemblies.

Abstract: Hybrid polymersomes, where the polymersome membrane is blended with phospholipids, display interesting self-assembly behavior and incorporate the robustness and chemical versatility of polymersomes, with the softness and biocompatibility of liposomes. Such structures can conveniently be characterized by the formation of giant vesicles formed via electroformation. We were interested to show the behavior of these giant structures correlate with that of nanoscale hybrid polymersomes of the same (initial) composition, an architecture that has so far not been thoroughly investigated. It is shown that the stability and compound release behavior of nanoscale polybutadiene-PEG/POPC hybrid polymersomes can be tuned by the mixing ratio of the amphiphiles, analogous to the way in which the drug-release behavior of phospholipid vesicles can be tuned by ‘pegylation’. In brief, these hybrids provide alternative tools for drug delivery purposes and molecular imaging/sensing applications that clearly warrant further study.

Title: Tetrachloride Transition-metal dianion-induced Ccoordination and Supramolecular self-Assembly of Strontium Dications to Cucurbit8uril

Abstract: In the present work, we describe a kind of novel cucurbit8uril-based coordination supramolecular self-assemblies in the presence of tetrachloride transition-metal dianion ([MtransCl4]2-, Mtrans = Cd, Zn, Cu, Co) in the HCl solution. Again the “honeycomb effect” of the tetrachloride transition-metal dianion ([MtransCl4]2- has been observed in the coordination of strontium cations to cucurbit8uril molecules (Q8s). It seems that the [MtransCl4]2− anions form honeycomb structure with hexagonal cells filled with the Sr2+-Q8 linear coordination polymers in which the Sr2+ cations coordinate to Q8 molecules and form zigzag coordination polymers.
