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

Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

Macromolecular Rapid Communications, EarlyView.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...

Surface photochemistry: benzophenone as a probe for the study of silica and reversed-phase silica surfaces [PDF]

, 2006
This work reports the use of benzophenone, a very well characterized probe, to study new hosts: two reversed-phase silicas. Laser-induced room temperature luminescence of argon purged solid powdered samples of benzophenone adsorbed onto the two different

Optical Durability of Contemporary PV Encapsulants Through Artificial UV Weathering

Progress in Photovoltaics: Research and Applications, EarlyView.
Encapsulant choice can be used to mitigate UV‐induced degradation in modern silicon photovoltaic modules, but this strategy is only effective if encapsulants are durable under UV weathering. This study identifies optical changes to 14 commercial encapsulants as a function of UV weathering and identifies that, while changes to material transmittance ...

Bioconjugation Strategies for Revealing the Roles of Glycerophospholipids in Cells. [PDF]

Chembiochem
Glycerophospholipids are the main class of phospholipids, essential for membrane structure, compartmentalization, and cellular signaling. To study their roles, innovative probes and advanced bioconjugation strategies have been developed, including by de novo lipid synthesis and bioorthogonal conjugation chemistry.

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

Smart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.
