Automated Alignment Powered by Computer Vision Streamlines the Two‐Photon Polymerization‐Based Micro 3D Printing of Multiscale and Multimaterial Structures

Advanced Intelligent Discovery, EarlyView.
Two‐photon polymerization enables high‐resolution microfabrication, but performing alignment when printing multiple structures is difficult. Here, we present a fast, robust, and open‐source protocol for automated alignment on Nanoscribe systems. Achieving ≈0.4 μm accuracy in under 5 s, our protocol reduces time and error in multimaterial printing. This

Iron Catalyzed Aryl–Aryl Kumada Cross‐Coupling: A Mechanistic and Computational Investigation

Angewandte Chemie, EarlyView.
Despite intense interest, the mechanism of iron‐catalyzed aryl–aryl cross‐coupling remains poorly understood. Combining Mössbauer spectroscopy, kinetics analysis, and DFT computations these studies reveal a novel Fe(I)/Fe(II)/Fe(III) catalytic for aryl–aryl cross‐coupling mediated by an Fe(II) PCNHCP Pincer complex. These findings close a key knowledge

Bayesian Optimisation for the Experimental Sciences: A Practical Guide to Data‐Efficient Optimisation of Laboratory Workflows

Advanced Intelligent Systems, EarlyView.
This study provides an introduction to Bayesian optimisation targeted for experimentalists. It explains core concepts, surrogate modelling, and acquisition strategies, and addresses common real‐world challenges such as noise, constraints, mixed variables, scalability, and automation.

A Convenient, Safe, and Atom‐Economical Route to a Large Portfolio of Grubbs‐Type Catalysts for Olefin Metathesis via Four‐Coordinate Ruthenium Alkylidynes

Angewandte Chemie, EarlyView.
It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Electrothermally Controlled 3D‐Printed Shape Memory Polymers for Near‐Ambient Temperature Soft Robotic Applications

Advanced Intelligent Systems, EarlyView.
In this article, we develop bespoke resins for stereolithography 3D‐printing of soft‐robotic grippers that are controlled remotely by electrothermal stimulus near ambient temperatures. Turning on the electrical control, each finger can be actuated separately.

Organophosphides: A New Class of Luminophore Ligands for Copper(I) Carbene Based TADF Emitters and Photocatalysts

Angewandte Chemie International Edition, EarlyView.
Dimesitylphosphide as a heavier congener of established amide ligands for charge‐transfer copper(I) complexes leads to bathochromic shift of the emission by up to 3645 cm−1 into the orange‐red (solid, polymer films) and even NIR (solution). The thermally activated delayed fluorescence exhibits high dissymmetry factors of glum = 10−2 in polystyrene.

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers

Angewandte Chemie International Edition, EarlyView.
Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.
