“…The discussed lipid vesicle membranes are good and excellent material for biomimetic construction of processes, but their dynamic and relatively labile molecular and material properties might be disadvantageous for large scale solar fuel production. Polymer based vesicles (so called polymersomes) have proven to be very versatile in properties [46,47,56,[48][49][50][51][52][53][54][55] as well as opportunities for functionalization with proteins such as transmembrane proteins. [57] Polymersome membranes are generally constructed by selfassembly of individual AB or ABC linear, branched or dendritic copolymers (examples for linear copolymers see Figure 2).…”

Lipid bilayer membranes are ubiquitous in natural chemical conversions. They enable self-assembly and compartmentalization of reaction partners and it becomes increasingly evident that a thorough fundamental understanding of these concepts is highly desirable for chemical reactions and solar energy conversion with artificial systems. This minireview focusses on selected case studies from recent years, most of which were inspired by either membrane-facilitated light harvesting or respective charge transfer. The main focus is on highly biomimetic liposomes with artificial chromophores, and some cases for polymer-membranes will be made. Furthermore, we categorized these studies into energy transfer and electron transfer, with phospholipid vesicles, and polymer membranes for light-driven reactions.

“…More drastic shape transformations were observed for polymersomes of alternating copolymers while being driven out-of-equilibrium through the BZ reaction [ 153 ]. Poly(2,3-dihydroxybutylene- alt -bipyridyl-dithioether) (P(DHB- alt -BpyDT) copolymers were synthesized from 5,5′-bis(mercaptomethyl)-2,2′-bipyridine and 1,3-butadienediepoxide via step-growth polymerization in the presence of triethylamine in DMF (epoxy/thiol “click” polymerization).…”

Recent Advances in the Synthesis and Application of Polymer Compartments for Catalysis

Catalysis is one of the most important processes in nature, science, and technology, that enables the energy efficient synthesis of essential organic compounds, pharmaceutically active substances, and molecular energy sources. In nature, catalytic reactions typically occur in aqueous environments involving multiple catalytic sites. To prevent the deactivation of catalysts in water or avoid unwanted cross-reactions, catalysts are often site-isolated in nanopockets or separately stored in compartments. These concepts have inspired the design of a range of synthetic nanoreactors that allow otherwise unfeasible catalytic reactions in aqueous environments. Since the field of nanoreactors is evolving rapidly, we here summarize—from a personal perspective—prominent and recent examples for polymer nanoreactors with emphasis on their synthesis and their ability to catalyze reactions in dispersion. Examples comprise the incorporation of catalytic sites into hydrophobic nanodomains of single chain polymer nanoparticles, molecular polymer nanoparticles, and block copolymer micelles and vesicles. We focus on catalytic reactions mediated by transition metal and organocatalysts, and the separate storage of multiple catalysts for one-pot cascade reactions. Efforts devoted to the field of nanoreactors are relevant for catalytic chemistry and nanotechnology, as well as the synthesis of pharmaceutical and natural compounds. Optimized nanoreactors will aid in the development of more potent catalytic systems for green and fast reaction sequences contributing to sustainable chemistry by reducing waste of solvents, reagents, and energy.

“…In particular, synthetic systems of nonequilibrium self-assembly driven by chemical fuels have attracted immense attention because they could closely mimic structures and processes of nonequilibrium self-assembly in the living body. [22,24,39] To date, nonequilibrium self-assembly systems mediated by chemical fuels, such as transient nanoreactors, [40][41][42] hydrogels, [4,[43][44][45][46][47][48][49] supramolecular polymerization, [23,50,51] structure switching, [52][53][54] transient coacervates, [55] and photonic materials [56] have been explored. Despite the significant advances in nonequilibrium self-assembly, the number of successful nonequilibrium self-assembly systems driven by chemical fuels remains rather limited.…”

Synthetic systems of nonequilibrium self-assembly have made considerable progress; however, the achievement of innovative materials with self-regulated functions analogous to living systems remains a grand challenge. Herein, a versatile nonequilibrium system of polymer brushes with spatiotemporally programmable properties and functions driven by chemical fuels is reported. By combining a responsive polymer with an autonomous pH regulator, the polymer brushes self-regulate their swelling and deswelling process with tunable lifetimes. By using patterned copolymer brushes with pH-responsive fluorescence moiety, an autonomous fluorescence modulator is created that self-regulates its fluorescence in spatiotemporally programmable fashion driven by a chemical or an enzymatic reaction. Furthermore, a self-regulated wettability switcher of polymer brushes both in air and in an aqueous solution is implemented. The methodology and results in the work provide a useful avenue into the exploration of nonequilibrium synthetic materials with programmable functions and would accelerate the transformative developments of nonequilibrium materials and systems in practical applications.
