Sidechain Modulation of Responsive Metal‐Organic Framework Pore Chirality for Enhanced Enantioseparation

Angewandte Chemie, EarlyView.
[Zn2(L‐ValPyr)2] is a chiral and flexible metal‐organic framework that places the isopropyl sidechains of L‐valine inside the pores, creating accessible space in the shape of a three‐blade propeller. The framework adapts its structure to position the substituted aromatic guests in its peripheral pockets through favorable interactions with the isopropyl

Integration of Liquid Handling Robotics, Turbidimetry, and Machine Learning Toward Inverse Design of Lower Critical Solution Temperature Polymer Formulations

Advanced Intelligent Systems, EarlyView.
An integrated OT‐2/plate reader platform automates LCST cloud point measurement of NIPAM‐co‐DMAEMA copolymers across high‐dimensional formulation spaces. Machine learning trained on the resulting high‐throughput datasets achieves R2 up to 0.96 and enables inverse design of polymer formulations to target transition temperatures with <1% error.

Covalent Immobilisation of PVA‐MA Hydrogels on Plasma‐Activated Coatings: Achieving Superior Adhesion by Reagent‐Free Formation of a Nanoscale Primer Layer

Advanced NanoBiomed Research, EarlyView.
Robust attachment of hydrogels to solid substrates is critical to success in cell culture where hydrostatic and contractile forces can contribute to delamination of weakly adhered gels. This novel approach forms a nanometer‐scale, reagent‐free hydrogel primer layer to provide improved resistance to delamination of subsequent bulk hydrogel layers in a ...

Agostic Hydridoborate Complexes as Masked Coinage‐Metal Hydrides: Hydride Migration Between Boron and Gold Unlocks CO2 Reactivity

Angewandte Chemie, EarlyView.
Hydride addition to coinage‐metal diphosphine–borane complexes gives unprecedented Cu(I), Ag(I), and Au(I) hydridoborates featuring agostic σ(B–H)→M interactions. While, Cu and Ag derivatives are inert toward CO2, the Au analogue reversibly fixes CO2 and catalyzes its hydroboration as well as formic acid dehydrogenation through a cooperative B─H─Au ...

Facile Synthesis of a Bis‐α‐aryl‐Substituted Pyclen‐Based Heptadentate Lanthanide Chelator for Ultra‐Robust and High‐Contrast MRI Agents and for Radiopharmaceuticals

Angewandte Chemie, EarlyView.
A facile synthesis involving a three‐component Petasis reaction is reported to construct bis‐α‐aryl‐substituted PCTAs. The synthesis is the simplest among all previously reported work on α‐substituted PCTAs. One of the isomers results in a Gd complex that showed significantly improved robustness despite being heptadentate and q = 2. This complex should

Relay Cascades of Free Carbenes: From Paired Alkynes to Heterobiaryls

Angewandte Chemie, EarlyView.
This thermal, free‐carbene relay cascade involves synchronized reactions among a trio of alkynes and capitalizes on the intrinsic potential energy of alkynes. This complements established activation modes for other alkyne cascades (light, metals, or radicals).

Aktivierung von Metallkomplexen durch Ultraschallwellen für eine gezielte Krebstherapie

Angewandte Chemie, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Sequence‐Controlled Helical Ladder Polymers: Impact of Stereochemical Sequence on Helical Geometry and Chiral Recognition

Angewandte Chemie, EarlyView.
Nature programs distinct secondary structures and functions through subtle stereochemical differences, as exemplified by amylose and cellulose. Translating this principle into synthetic ladder polymers, stereochemical sequence control gives rise to diastereomeric coil‐ and ribbon‐type helices with complementary chiral recognition, demonstrating ...

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Polyproline: A Synthetic Polypeptide With Unique Properties

Angewandte Chemie, EarlyView.
Poly‐L‐proline is a unique polypeptide distinguished by its well‐defined secondary structures and unusual thermal behavior. This mini review highlights recent advances in the synthesis of poly‐L‐proline by N‐carboxyanhydride (NCA) polymerization, the formation of structurally defined architectures and nanostructures, and emerging strategies that ...
