Methyl 2-hy-droxy-4-iodo-benzoate.

The structure of the title compound, CHIO, at 90 K has monoclinic (2/) symmetry. The extended structure is layered and displays inter-molecular and intra-molecular hydrogen bonding arising from the same OH group.

Determination of the dehydration pathway in a flexible metal-organic framework by dynamic x-ray diffraction.

Understanding guest exchange processes in metal-organic frameworks is an important step toward the rational design of functional materials with tailor-made properties. The dehydration of the flexible metal-organic framework [Co(AIP)(bpy)0.5(HO)]•2HO was studied by novel dynamic x-ray diffraction techniques.

A Suzuki Approach to Quinone-Based Diarylethene Photochromes.

Diarylethene photochromes show promise for use in advanced organic electronic and photonic materials with burgeoning considerations for biological applications; however, these compounds typically require UV light for photoswitching in at least one direction, thus limiting their appeal. We here introduce a naphthoquinone-based diarylethene that switches between open and closed forms with visible light. The synthesis of this quinone diarylethene relies on Suzuki methodology, allowing for the inclusion of functional groups not otherwise accessible with current synthetic routes.
