Manipulation of Chemistry and Biology with Visible Light Using Tetra‐ortho‐Substituted Azobenzenes and Azonium Ions

Angewandte Chemie, EarlyView.
Tetra‐ortho‐Azobenzenes (TOABs) in broad daylight: in recent years, TOAB photoswitches became indispensable tools for all‐visible‐light manipulation of chemistry, biology and materials. This review explores their unique photochemical properties, design and synthetic approaches, offering support in choosing a TOAB for a given application.

Controllable Antiferromagnetic to Ferromagnetic Transition of CrSBr by Organic Cation Intercalation

Advanced Electronic Materials, EarlyView.
The phase transformation of antiferromagnetic CrSBr into ferromagnetic TBA‐CrSBr is realized by intercalating organic TBA⁺ cations into its van der Waals gap. The temperature dependence of magnetization unambiguously shows the typical antiferromagnetic and ferromagnetic behavior for pristine CrSBr and intercalated TBA‐CrSBr, respectively.

Intrinsically Disordered Peptide Nanofibers from a Structured Motif Within Proteins

Angewandte Chemie, EarlyView.
The sequence (PQYQP), derived from the SRC protein, was combined with the self‐assembly motif (Nap‐FF) to produce intrinsically disordered peptide (IDP) assemblies that form cell‐compatible hydrogels via enzyme‐instructed self‐assembly (EISA). Abstract Intrinsically disordered regions (IDRs) are ubiquitous in proteins, orchestrating complex cellular ...

Chiral Luminescent Ion Pair (CLIP) Strategy Enables Amorphous Platinum Complexes Circularly Polarized Phosphorescence

Angewandte Chemie, EarlyView.
A series of chiral luminescent ion pair (CLIP) materials based on chiral anion strategy were synthesized with high‐performance circularly polarized phosphorescence (CPP) in amorphous states. The trade‐off problem between good processability and high asymmetry factor was solved by constructing CLIP molecules and utilizing polymer entanglement or rapid ...

Supramolecular Gels as Active Tools for Reaction Engineering

Angewandte Chemie, EarlyView.
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Solvent‐Directed Handedness in a Chirally Twisted Tetrakisporphyrin Macrocycle

Asian Journal of Organic Chemistry, EarlyView.
A chirally twisted tetrakisporphyrin macrocycle was synthesized by incorporating a chiral dioxolane into a tetrakisporphyrin macrocycle. The solvent type influenced the preferred handedness of the twisted conformation. Circular dichroism measurements and computational analyses determined the handedness of the conformers in solvents toluene and ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis

Asian Journal of Organic Chemistry, EarlyView.
This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.
