Single-crystal X-ray diffraction (SCXRD) is a widely used method for structural characterization. Generally, low temperature is of great significance for improving the crystallographic diffraction quality. Herein we observe that this practice is not always effective for flexible metal-organic frameworks (-MOFs).

Herein, we present a trichromatic white-light-emitting metal-organic framework (MOF) composite () by simultaneously incorporating red/green-emitting Pt/Ru complex cations into porous blue-emitting bio-MOF-1 through post-synthetic modification. With the help of a three-dimensional (3-D) dual-ratiometric luminescence recognition method, and unique turn-on responses of the red emission toward amine compounds (ACs), including NH and aliphatic amines, via confinement-induced luminescence enhancement effect, can work as a dual-ratiometric luminescent sensor for discrimination of 7 out of 11 AC vapors.

Herein, a new facile solvothermal method was developed, and four quaternary copper sulfides, i.e.

Their high power conversion efficiency, being comparable to that of Pt CE, was achieved due to their good conductivity and high heteroatom content.
