Design and synthesis of responsive glycopolymers for biomedical and environmental applications

open access: yesResponsive Materials, EarlyView.
This review highlighted recent advances in the synthetic methodology of polymerization and post‐polymerization modification, which enable precise structural control and broaden the applications of responsive glycopolymers in biomedical and environmental fields. Abstract Glycopolymers are a unique class of synthetic polymers bearing pendant carbohydrate

Azobenzene‐based molecular solar thermal integrated with phase change materials for smart thermoregulating textiles

open access: yesResponsive Materials, EarlyView.
This work introduces azobenzene (azo)‐based molecular solar thermal energy storage systems with phase change materials (PCM): molecular engineering toward smart textiles. Integrating Azo with PCM, the fabric captures solar energy and ambient heat concurrently.

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

open access: yesSmall, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

Interplay Between Oxidation State, Intervalence Charge Transfer Transitions and Electronic Conductivity in a Series of Ru‐Based Metal–Organic Frameworks

open access: yesSmall, EarlyView.
Ru‐based square‐grid metal–organic frameworks undergo dramatic conductivity enhancements after chemical oxidation. The mixed‐valent states exhibit the highest conductivity values, which correlate with the appearance of intervalence charge transfer bands.

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

open access: yesSmall, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

An ‘Empty’ [Fe16] Cage and its Transformation into [Fe17] and [Fe30]

open access: yesSmall, EarlyView.
Polymetallic clusters of FeIII constructed without organic bridging ligands are an emerging class of molecules with structures akin to iron oxide minerals, possessing large spin ground states and/or displaying spin frustration effects. All previous examples, [Fe8], [Fe17], [Fe30] and [Fe34], have been isolated from pyridine or analogous heterocyclic ...
