“…Meanwhile, fiber-like polymers were observed between the NPs (Figure c inset). Transmission electron microscopy (TEM) measurements clearly display polymers surrounding the ZIF-8-P(MMA- co -AAAB) NPs (indicated by gray regions), , which are not observed for ZIF-8 (Figure e,f). The ZIF-8-P(MMA- co -AAAB) NPs were digested in sulfuric acid and analyzed by 1 H NMR.…”

Two-dimensional metal−organic framework (MOF) monolayer films, which can be considered as large-area, periodically ordered thin films with atom-or single-unit thickness, have attracted extensive attention due to their special properties and wide range of potential applications. However, the preparation of MOF monolayer films is still a great challenge, and the introduction of functional groups into MOF monolayer films is seldom reported. Here, we report the first centimeterscale, photo-switchable, free-standing MOF monolayer film formed by self-assembly of poly(methyl methacrylate-co-acrylamidoazobenzene)-coated MOF nanoparticles at the water−air interface. This self-assembled MOF monolayer film is extremely thin (∼220 or 50 nm) and has a high MOF loading (85 wt %), while exhibiting remarkable reversible photoswitching properties under alternating exposure to 365 nm UV and white light. Inspired by this, a light-gated ion nanochannel device is fabricated, which enables reversible ″OFF−ON″ changes of the ionic flux and has promising applications in the field of photoelectric conversion. This provides a modular route to design large-area, free-standing functional MOF monolayer films.

Charged block copolymers (BCPs) find use in numerous applications spanning from gene delivery to electromechanical transducers. Recent advances in polymer synthesis have provided researchers with the necessary tools to study the properties of a wide variety of BCPs bearing cationic and anionic substituents. Controlling the architecture of these charged BCPs plays a key role in tailoring their performances in the desired application. Likewise, the polymer morphology significantly affects ion transport and thermomechanical properties of the charged BCP. This article aims to compare the structure–property relationships in charged BCPs across a variety of different polymer architectures including linear, branched, segmented, and multiply charged BCPs with a focus on tailoring properties for specific applications. Linear BCPs comprise of diblock, triblock, and multiblock copolymers. Diblocks frequently serve as micelles for drug delivery while triblocks, multiblocks, and segmented BCPs act as ion exchange membranes for transducers and fuel cells. The section on branched BCPs discusses polymer brushes, stars, micelles, and cross‐linked networks. The final section describes synthetic routes toward synthesizing multiply charged monomers and polymers while also emphasizing the challenges and benefits associated with these materials.
