Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds

Advanced Optical Materials, EarlyView.
In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

Single‐Layer Cholesteric Liquid Crystal Polymer Films With Visible Broadband Reflection

Advanced Optical Materials, EarlyView.
A single‐layer spin‐coated cholesteric liquid crystal polymer film exhibiting broadband reflection across the visible spectrum is demonstrated. By controlling photopolymerization‐induced pitch‐gradient formation, the film achieves low‐scattering broadband reflection, circular polarization selectivity, and compatibility with photolithographic patterning

White Light Emission and Energy Transfer in Mixed‐Metal Europium/Terbium/Thulium Formate Metal–Organic Frameworks: Effect of Lanthanum Dilution

Advanced Optical Materials, EarlyView.
A series of Eu3+, Tb3+, Tm3+ and La3+ formate‐based (mixed)metal‐organic frameworks were synthesized and investigated for energy transfer and white‐light emission. Efficient Tb3+→Eu3+ transfer enabled tuneable luminescence, while Tm3+ incorporation afforded near‐white emission.

Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence.
