Bright and Stable Electrochemiluminescence by Heterobimetallic IrIII‐MI (MI = CuI, AuI) Complexes

open access: yesAdvanced Optical Materials, EarlyView.
Bright and stable electrochemiluminescence (ECL) of a new class of heterobimetallic ionic transition metal complexes is triggered in the presence of the coreactant n‐tri propylamine (TPrA) upon highly energetic electron transfer (eT). A quantum efficiency (ΦECL) up to six‐fold higher than that of benchmark tris‐(2,2′‐bipyridyl) ruthenium(II) is ...

Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels

open access: yesAdvanced Optical Materials, EarlyView.
Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

open access: yesAdvanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...

Enhanced Amplified Spontaneous Emission from Optically Pumped Perovskite Light‐Emitting Diodes with Sodium Fluoride Additives

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates sodium fluoride (NaF) as an additive in halide perovskite films to improve their optical and light amplification properties for application in laser diodes. The incorporation of NaF leads to a threefold increase in light‐emitting intensity and a 20% reduction in the amplified spontaneous emission (ASE) threshold, along with ...

Effective and Practical Stereoselective Synthesis of Nutlins Precursors by Immobilization of Privileged Chiral Mono‐Amidine Catalyst

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A strategy for the immobilization of Johnston's Mono(AMidine) catalyst (MAM) onto polystyrene, silica and hybrid silica‐polystyrene nanoparticles is presented. The catalyst activity was evaluated in the stereoselective aza‐Henry reaction leading to the pivotal β‐amino nitroalkane precursors of the anti‐cancer agents Nutlins (with Nutlin‐3a as ...
