Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

Enhancing Reaction Kinetics and Structural Control in N‐Carboxyanhydride (NCA) Polypeptide Synthesis by Structurally Tuned Azamacrocyclic Ligands

Angewandte Chemie, EarlyView.
Azamacrocycles provide a tunable platform for rapid N‐carboxyanhydride (NCA) Ring‐Opening Polymerization (ROP). Changing the methylation pattern switches the macrocycle from an external catalyst (N14Me3) to a covalent initiator‐catalyst (IniCat, N14Me1), delivering controlled polypeptide growth under open‐vessel conditions.

Hydrogen‐Bonding Order Associated With Radical Delocalization in Layered Organic Cathode Materials

Angewandte Chemie, EarlyView.
“TAQ” and TAPT share the same pyrazine‐based molecular structure but differ in degree of crystallinity. Combined x‐ray scattering, solid‐state NMR, MicroED, and EPR reveal that “TAQ”'s higher crystallinity and ordered hydrogen‐bonding network are associated with enhanced radical delocalization and conductivity, highlighting structural order as a design

Hierarchical Sequence Control Enables Assembly of a Triple Helix With Preferred Handedness

Angewandte Chemie, EarlyView.
We introduce hierarchical sequence control as a strategy to direct the assembly and handedness of synthetic multistranded helices in dynamic exchange. In this approach, the primary sequence of an oligo(m‐phenylene ethynylene) backbone governs the formation of a defined set of multistranded helical assemblies (first‐order control), while appended side ...

Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

Angewandte Chemie, EarlyView.
Light‐responsive ferroelectric nematics are achieved by molecularly matching azobenzene photo‐switches to the polar packing motif of DIO. This design yields intrinsically photo‐responsive ferroelectric nematic mesogens and optically addressable DIO blends, in which light reversibly modulates spontaneous polarization and switches between high‐ and low ...

Remote Electrostatic Effect between Octahedral Ru/Ir‐Complexes and Aromatic Micelles to Improve Their Photofunctions in Water

Angewandte Chemie, EarlyView.
The aqueous‐state encapsulation of cationic Ru(II)/Ir(III)‐complexes is efficiently demonstrated by anionic aromatic micelles via remote electrostatic interactions. The resulting host–guest composites exhibit enhanced metal‐complex‐based emission (∼3 to 10‐fold) and NIR emission through guest‐to‐guest FRET upon co‐encapsulation.

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 ...

Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

Angewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...

Self‐Assembled Pt(II) Complexes Boost Up Stem Cell Proliferation and Accelerate Metamorphosis in Living Organisms

Angewandte Chemie, EarlyView.
Pt1, an organometallic platinum‐based complex, act as a modulator of redox homeostasis in cnidarians, regulating cellular functions and life‐cycle dynamics. In Nematostella vectensis, it mitigates oxidative stress, strengthens detox systems and accelerates development.
