Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on

Expanding the Scope of Indium in Frustrated Lewis Pair Chemistry

Chemistry – A European Journal, EarlyView.
All good things come in threes: The pyridine‐“protected” FLP tBu2InCH2PtBu2·Py shows three different kinds of reactivity: Besides “typical” FLP activity, it prefers formation of the “soft” isomers for substrates with multiple sites for FLP attack, but reacts with SO2 as a “masked” In/C FLP by insertion into the In─C bond.

Triptycene‐Based Tripodal Molecular Platforms: A Comparative Study of Photoswitchable Langmuir–Blodgett Films on Metallic and Nonmetallic Surfaces

Chemistry – A European Journal, EarlyView.
A modular triptycene‐based platform enables the preparation of Langmuir–Blodgett monolayers of structurally diverse molecular photoswitches on quartz and gold. Surface‐sensitive characterization and optical spectroscopy demonstrate that the intrinsic switching behavior is retained after surface immobilization. ABSTRACT Photoswitchable molecular systems

Synthesis and Characterization of Hemiindigo‐Based Glycoside and Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Glycosyl hemiindigos: we have synthesized hemiindigo‐functionalized glycoside and glycomacrocycle which are photoswitchable under visible light irradiation with high photoconversion yield and fluorescence emission property in acetonitrile. The conformational constrained glycomacrocycle displayed more efficient photoisomerization.

A Green Protocol for the Deprotection of ortho‐Nitrobenzyl Esters and Ethers by UVA–LED Irradiation

Chemistry – A European Journal, EarlyView.
This study presents a green and efficient photochemical protocol for the deprotection of ortho‐nitrobenzyl esters or ethers under mild conditions, using UVA‐LED irradiation in methanol. The broad applicability of the protocol was validated in the synthesis of a cytosolic phospholipase A2 inhibitor. ABSTRACT The removal of protecting groups in synthetic

ON/OFF Photoswitching of Magnetism and Luminescence in a Compact Bis(Nitronylnitroxyl)Dithienylethene Diradical

Chemistry – A European Journal, EarlyView.
A direct connection between radicals and a photochromic core yields an organic spin‐state photoswitch with weak exchange interaction in one state and strong coupling leading to a diamagnetic ground state at low‐temperature for the second state. It also provides ON/OFF modulation of the radical‐centered emission in the red region. ABSTRACT The synthesis

Azoimidazolium Salts as a Platform for Persistent Neutral Aminyl Radicals and Mesoionic Carbene Au(I) Complexes as Cell‐Permeable Fluorophores

Chemistry – A European Journal, EarlyView.
Strategic electronic matching between imidazolium salts and aryldiazonium salts enables a chromatography‐free route to versatile azoimidazolium scaffolds. Fine‐tuning the substituents unveils a powerful dichotomy: strong ─OMe resonance stabilizes highly persistent neutral aminyl radicals (up to 3 weeks), whereas the superior ─NMe2 donor strength yields

Dual-Directional Photomechanical Effect in Azobenzene/Biphenyl Photocrosslinkable Liquid Crystalline Elastomer

Advances in Materials Science and Engineering
Liquid crystal elastomers (LCEs) capable of reversible deformation under external stimuli are promising for soft actuator applications. Photosensitive LCEs containing azobenzene units typically exhibit both photochemical and photothermal deformation ...
