Xenon Trioxide Coordination Complexes of Crown Ethers: (CH2CH2O)4XeO3 and Xe(VI) Hydrates, [(CH2CH2O)6(H2O)XeO3]⋅ H2O and [(CH2CH2O)6(H2O)XeO3]2 ⋅ 2H2O ⋅ HF

open access: yesAngewandte Chemie, EarlyView.
Quenching xenon's thirst by its coordination to water in the 18‐crown‐6 complexes, [(CH2CH2O)6(H2O)XeO3] ⋅ H2O and [(CH2CH2O)6(H2O)XeO3]2⋅ 2H2O ⋅ HF, provides the first examples of Xe‐ ‐ ‐O bonded noble‐gas hydrates. These complexes, along with (CH2CH2O)4XeO3, were characterized by Raman spectroscopy, X‐ray crystallography, and computational studies ...

Free‐space Optical Computing Systems

open access: yesAnnalen der Physik, EarlyView.
Manipulation and propagation of optical wavefronts in free space enables new intelligent computing hardware. Two types of optical computing systems, matrix and vector multiplication systems and diffractive optical neural network systems, are reviewed from material, device, and system aspects.

Using Color to Control Conformation in a Chemical System Containing Multiple Tricyanofuran Photoacids

open access: yesAngewandte Chemie, EarlyView.
In a solution of two metastable photoacids with contrasting absorption maxima, the solution pH may be control by varying the wavelength of the visible light input. This pH change governs the interaction between the Zn2+ cation and two competing anionic chiral ligands, detected by a change in circular dichroism (CD) spectra.

A Hypoxia‐Triggered Bioreduction of Hydrophilic Type I Photosensitizer for Switchable In Vivo Photoacoustic Imaging and High‐Specificity Cancer Phototherapy

open access: yesAngewandte Chemie, EarlyView.
A hydrophilic type I phototherapeutic agent (NanoPcN8O) was developed which selectively responded to hypoxic tumor microenvironments and switched on type I photodynamic and photothermal effects as well as a photoacoustic signal for activatable photoacoustic imaging and tumor phototherapy.
