Quercetin•Zirconium Metal Complexes: Insights from Femto to Millisecond Photobehavior
Chemistry – A European Journal, EarlyView.The switching off of excited‐state intramolecular proton transfer (ESIPT), followed by the switching on of ligand‐to‐metal charge transfer (LMCT) processes in quercetin (QRT)•Zr complexes, is crucial for generating Zr‐bound QRT radicals that exhibit significantly shorter lifetimes compared to free QRT radicals.

Chemistry – A European Journal, EarlyView.This article describes the synthesis, along with the full photophysical and computational characterization, of a series of push‐pull boron complexes comprising a sterically hindered donor connected to a pyrimidine‐based O^N^O boron chelate. Incorporation of the dimethylacridan derivative into an organic light‐emitting diode led to the observation of ...

A General Approach to Dropout in Quantum Neural Networks
Advanced Quantum Technologies, EarlyView., 2023 Randomly dropping artificial neurons and all their connections in the training phase reduces overfitting issues in classical neural networks, thus improving performances on previously unseen data. The authors introduce different dropout strategies applied to quantum neural networks, learning models based on parametrized quantum circuits.

Chemistry – A European Journal, EarlyView.A novel family of water‐soluble, nontoxic, and phosphorescent N‐glycosylated Ru(II) phenanthroline‐based complexes are reported. They exhibit photoselectivity indexes ranging from 10 to 44 in PC‐3 cells, while impacting cell migration and resistance to detachment after irradiation with blue light.

Benefits of Open Quantum Systems for Quantum Machine Learning
Advanced Quantum Technologies, EarlyView., 2023 Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

Boost of Chiroptical Responses Through the Enhancement of Electron Transition Dipole Moment
Chemistry – A European Journal, EarlyView.Chiral spirobifluorene systems are peripherally π‐extended via Knoevenagel condensation to boost their electric transition dipole moments (ETDM). A direct ETDM–g‐factor correlation is established through ECD and TD‐DFT analyses. This strategy allows precise control of exciton coupling and chiroptical amplification in rigid π‐conjugated scaffolds ...
