Single‐Particle FRET Probes Heterogeneity in the Ligand Shell of Colloidal Perovskite Quantum Dots

Advanced Materials, EarlyView.
Single‐particle, single‐molecule Förster resonance energy transfer turns dye‐tagged ligands into nanorulers for the otherwise elusive organic shell of CsPbBr3 quantum dots. Distance variations within individual particles reveal pronounced local heterogeneity, while changes in the surrounding ligand chemistry shift the average dye–surface separation ...

UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces

Advanced Materials Interfaces, EarlyView.
PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.

Thermoplastic Dielectric Coatings for Flexible Electrodynamic Dust Shields: Structural and Functional Performance

Advanced Materials Interfaces, EarlyView.
Thermoplastic attachment is introduced as a scalable surface coating strategy to improve the durability and dielectric reliability of flexible electrodynamic dust shields. By embedding chemically modified reduced graphene oxide (CMrGO) electrodes within thermoplastic laminates, mechanical degradation, abrasion damage, and vacuum‐induced electrical ...

In Situ Forming, Dual-Crosslink Network, Self-Healing Hydrogel Enabled by a Bioorthogonal Nopoldiol–Benzoxaborolate Click Reaction with a Wide pH Range

, 2019
The use of click chemistry as a hydrogel cross-linking reaction is often limited by slow reaction rates and harsh conditions, such as exposure to UV light and/or use of nonspecific or toxic reagents.

Click-to-Release Reactions for Tertiary Amines and Pyridines

Journal of the American Chemical Society
Click-to-release reactions, transformations that liberate molecules of interest under physiological conditions, are gaining traction as powerful means to control biological processes and enable spatiotemporal drug delivery. A major limitation of current click-to-release strategies remains their narrow scope of releasable functional groups, leaving many

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

Advanced Optical Materials, EarlyView.
Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...
