Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement

Angewandte Chemie, EarlyView.
Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization

Circularly Polarized Red‐NIR Emission With High Dissymmetry Factor From Achiral [Mo6I8(OCOC2F5)6]2− Cluster Anion Embedded in a Bent‐Core Liquid Crystal Host

Advanced Optical Materials, EarlyView.
Associating a chiral bent core liquid crystal molecule, that self‐assembles into helical nanofilaments, with an achiral red‐NIR phosphorescent octahedral molybdenum cluster produces a hybrid material exhibiting efficient red‐NIR circularly polarized emission under UV excitation.

Layer-by-Layer Freezing of Nanoconfined Water [PDF]

Scientific Reports, 2020
AbstractNanoconfined water plays a pivotal role in a vast number of fields ranging from biological and materials sciences to catalysis, nanofluidics and geochemistry. Here, we report the freezing and melting behavior of water (D2O) nanoconfined in architected silica-based matrices including Vycor glass and mesoporous silica SBA-15 and SBA-16 with pore ...

Ga-In Alloy Segregation within a Porous Glass as Studied by SANS

Nanomaterials, 2023
Nanolattices can play the role of templates for metals and metallic alloys to produce functional nanocomposites with particular properties affected by nanoconfinement. To imitate the impact of nanoconfinement on the structure of solid eutectic alloys, we

Architected Inverse Nacre Hydrogels With High Strength and Crack‐Insensitive Toughness

Advanced Science, EarlyView.
Hydrogels hold promise for biomedical and engineering applications, yet their practical use is fundamentally limited by the strength‐toughness trade‐off and poor fatigue resistance. In this study, a bioinspired inverse nacre architecture constructed via a scalable thermo‐calendering process is introduced, which overcomes these classic limitations ...

Heterointerface Engineering of Bismuth Nanosheets/Nitrogen‐Doped Carbon Nanoleaves Enables High‑Performance Electrochemical Dechlorination

Advanced Science, EarlyView.
Bismuth nanosheets integrated with nitrogen‐doped carbon nanoleaves are constructed via a 2D‐on‐2D heterointerface engineering strategy. The resulting BiNS/NCL electrode delivers high chloride adsorption capacity, fast kinetics, and stable cyclability. A built‐in electric field at the heterointerface promotes chloride electrosorption and stabilizes the
