Reversible Single-Crystal-to-Single-Crystal Transformation and Magnetic Change of Nonporous Copper(II) Complexes by the Chemisorption/Desorption of HCl and HO.

Vapor-responsive magnetic materials are highly promising for applications as chemical switches or sensors. Compared with porous materials, nonporous species benefit in overcoming the intrinsic conflict between magnetic exchange and porosity but usually suffer from the powdering of single crystals, which hinders the understanding of the structural nature of vapor response and magnetic switch. Single-crystal-to-single-crystal (SCSC) transformation of nonporous compounds through the desorption/absorption of gaseous HCl is unprecedented.

Effects of Erxian decoction, a Chinese medicinal formulation, on serum lipid profile in a rat model of menopause.

Background: The prevalence and risk of cardiovascular disease increase after menopause in correlation with the progression of abnormality in the serum lipid profile and the deprivation of estrogen. Erxian decoction (EXD), a Chinese medicinal formulation for treating menopausal syndrome, stimulates ovarian estrogen biosynthesis. This study investigates whether EXD improves the serum lipid profile in a menopausal rat model.

Photochromic inorganic-organic hybrid: a new approach for switchable photoluminescence in the solid state and partial photochromic phenomenon.

A photochromic inorganic-organic hybrid based on in situ generated MV(2+) cation (MV(2+) = methyl viologen = N,N'-dimethyl-4,4'-bipyridinium) has been obtained, in which a vagarious partial photochromic phenomenon together with its photoluminescence modulation properties are reported for the first time in the inorganic-organic hybrids.

Inorganic-organic hybrid photochromic materials.

The distinct synergetic characteristics between each component in inorganic-organic hybrids offer various possibilities to obtain new "smart", high performing materials. Growing interest in this field has largely expanded the content of photochromic materials for the purpose of improving existing photochromic materials, fabricating photoresponsive devices, and exploring new families of photochromic materials. In this feature article, we give a brief review of photochromic hybrids of metal halides, metal cyanides, polyoxometalates, and metal chalcogenides as well as photochromic metal-organic complexes.
