Allosteric Regulation of Photophysics and Binding in Oxazine‐macrocycle Complexes at Single‐molecule Resolution

open access: yesAngewandte Chemie, EarlyView.
This work explores the interactions between the oxazine dye ATTO655 and two macrocyclic hosts using optical (single‑molecule) spectroscopy. Although ATTO655 forms a classical inclusion complex with cucurbit[8]uril (CB8), its interaction with p‑sulfonatocalix[4]arene (sCX4) leads to the formation of dim exclusion complexes.

Object oriented and relational specification of information systems

open access: yes, 1991
Taking a Deductive and an Object Oriented approach to specify Information Systems has become a rich research topic. Within this framework, RMOL [11] and its active evolution OASIS [13] [9] are two object- oriented specification languages that provide a ...

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Metal‐Free Active Template: A Straightforward Route to 4‐Aminopyridinium‐Based Rotaxane Molecular Shuttles

open access: yesAngewandte Chemie, EarlyView.
Leigh's metal‐free active template‐based SNAr of an amine on halogenopyridiniums, in the presence of a crown ether, successfully afforded 4‐aminopyridinium‐containing rotaxanes. Further molecular machinery was carried out by deprotonation‐then‐carbamoylation of the conjugated amino moiety.

Equilibrium Propagation for Dissipative Dynamics

open access: yesAdvanced Intelligent Systems, EarlyView.
This work develops local learning rules for damped linear dynamical systems, including mechanical structures and resistor‐inductor‐capacitor (RLC) circuits, by leveraging an effective action formulation. It demonstrates how physical systems can autonomously compute gradients and learn temporal patterns, enabling applications such as sound ...

Gold(III) Semiquinone Complexes: Synthesis, Structure, and Application in Photocatalysis

open access: yesAngewandte Chemie, EarlyView.
Au(III) catecholate complexes engage into electron donor acceptor (EDA) interactions with aryldiazonium salts, enabling single‐electron transfer under green light irradiation. Ligand‐centered one‐electron oxidation to stable semi‐quinone complexes provides a new platform for standalone Au(III) photoredox catalysis, as substantiated by the C–H arylation

Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

open access: yesAngewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...
