Synthesis of Heterocyclic Scaffolds from Nitrobenzyl Alcohols Using Reduction‐Generated Azaquinone Methides and Cyclization

European Journal of Organic Chemistry, EarlyView.
Intramolecular cyclization to quench an in situ reduction‐generated azaquinone methide is a strategy that could be used for late‐stage heterocycle synthesis. Herein, synthetically accessible 4‐nitrobenzyl alcohols with a nucleophilic handle adjacent to the benzyl alcohol group are reduced under mild conditions to afford six‐ and seven‐membered ...

Structural design and property regulation of organic polymers for photocatalytic synthesis of H2O2

InfoScience, EarlyView.
Photocatalytic synthesis of H2O2 offers a sustainable approach. Photocatalytic efficiency depends critically on interfacial electron transfer kinetics and spatial charge separation. Herein, we systematically analyze key factors governing photogenerated carrier dynamics and propose engineered strategies to optimize performance, thereby providing design ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Advancements in 3D Printing of Self‐Healing Polymer Systems

Macromolecular Materials and Engineering, EarlyView.
This review provides an overview of the most common 3D printing technologies and summarizes the numerous methods to produce self‐healing materials. The challenges and strategies used to adapt these methods to 3D printing are then highlighted to provide a framework for future research in 3D printing self‐healing polymer systems.

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

Macromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Diacetylene‐Functionalized Glycan Mimetics for Receptor‐Mediated Cluster Imprinting in Model Membranes

Macromolecular Rapid Communications, EarlyView.
Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular

A Non‐Antigenic Randomized Polyethylene Glycol/Poly(2‐Phenyl‐2‐Oxazine)‐Based Drug Delivery Platform

Macromolecular Rapid Communications, EarlyView.
Randomized PEG (rPEG), a conceptually new PEG alternative, is combined with poly(2‐phenyl‐2‐oxazine) (PPheOzi) to establish an rPEG‐b‐PPheOzi‐b‐rPEG micellar drug delivery platform. The PPheOzi block enables high drug loadings, while competitive ELISA reveals a drastic reduction in anti‐PEG antibody affinity of rPEG in comparison to PEG.

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

Macromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.
