Advanced Materials, EarlyView.The transient interactions between TFSI− anions and a diluent within an anion‐dictated electrolyte are revealed, which can reduce interfacial reorganization energy, thereby accelerating ion kinetics and markedly facilitating sustainable anion storage in high‐voltage graphite cathodes for dual‐ion batteries at fast charge and wide temperature range ...

Azaporphyrinoid‐Based Photo‐ and Electroactive Architectures for Advanced Functional Materials
Advanced Materials, EarlyView.A long‐standing collaboration between the Torres and Guldi groups has yielded diverse azaporphyrinoid‐based donor‐acceptor nanohybrids with promising applications in solar energy conversion. This conspectus highlights key molecular platforms and structure‐function relationships that govern light and charge management, supporting the rational design of ...

The Empirical Saddlepoint Estimator
, 2018 We define a moment-based estimator that maximizes the empirical saddlepoint (ESP) approximation of the distribution of solutions to empirical moment conditions. We call it the ESP estimator.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space
Advanced Materials, EarlyView.In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs
Advanced Optical Materials, EarlyView.The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.
