Excited State Modulation in Carbene‐Metal‐Amides to Design Fast and Bright Blue Delayed Fluorescence

open access: yesAdvanced Functional Materials, EarlyView.
Gold‐centered carbene‐metal amide (CMA) materials with carbonyl‐group substitution on the amide donor ligand. Molecular design ensures that the charge transfer (CT) state is lower in energy than the locally excited (3LE) states. The energy difference between CT and LE states controls the rate of the delayed fluorescence.

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

open access: yesAdvanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Chromaticity Control in Light‐Emitting Electrochemical Cells via Thermally Activated Emission in Assemblies of a BN‐Doped Pyrenyl Hydrocarbon

open access: yesAdvanced Functional Materials, EarlyView.
The successful color control in light‐emitting electrochemical cells based on highly emissive green‐emitting BN‐doped polyaromatic hydrocarbon with thermally activated NIR emitting assemblies. Abstract This work outlines the synthesis and photo‐/electro‐luminescent behavior of a new C‐shaped BN‐doped benzenoid hydrocarbon using N‐directed borylation in

Quantum Coherence and Quantum Correlations

open access: yes, 2017
We demonstrate a new type of optical coherence tomography (OCT) scheme based on ideas put forward by Mandel's group in 1991, curiously the same year than the first OCT scheme was demonstrated. It involves the measurement of the first-order correlation function (G(1)) between two beams that never interact with the sample under study.
