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

Advanced 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 ...

The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites

Advanced Optical Materials, EarlyView.
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.

Purinylidene‐Based Iridium(III) Phosphors for Efficient Purple Phosphorescence and Organic Light‐Emitting Devices

Advanced Photonics Research, EarlyView.
A family of purinylidene based Ir(III) emitters, namely, f‐ct2a–d, are synthesized and utilized as both dopants and sensitizers in the construction of efficient purple to deep‐blue organic light‐emitting diode devices. It is very challenging to achieve highly efficient and low roll‐off purple to deep‐blue organic light‐emitting diodes (OLEDs) due to ...

Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms

Advanced Photonics Research, EarlyView.
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion

Gram‐Scale Photocatalysis with a Stable and Recyclable Chromium(III) Photocatalyst in Acetonitrile and in Water

Advanced Synthesis &Catalysis, EarlyView.
Abstract The use of stable photosensitizers made on a multigram‐scale from cheap and available starting materials offers an extraordinary opportunity to translate small‐scale proof‐of‐concept photoreactions to widespread applications in non‐specialized laboratories, thereby promoting the implementation of light‐driven syntheses.
