A novel sodium-fluorescent crystal

In this work, a novel sodium-fluorescent crystal (Na-FS) was synthesized from 4-dimethylaminobenzoic acid and sodium hydroxide by one-pot hydrothermal method. The structure and conformation of Na-FS were confirmed by single-crystal X-ray diffraction and scanning electron microscope, and the optical properties were studied by fluorescence spectrometer. The results showed that: Na-FS was a triclinic crystal, space group was P-1, cell parameters a, b and c were 10.5113(3), 15.9198(5) and 15.9560(5) Å, respectively, and the number of independent atoms Z in a structure cell was two. Additionally, Na-FS has a blue fluorescence emission (around 360 nm under excited at the range of 230-300 nm) with great photostability and photobleaching resistance, and the quantum yield of Na-FS is 30.58%.

Two unique copper cluster-based metal–organic frameworks with high performance for CO2 adsorption and separation

Two unique Cu cluster-based MOFs have been constructed. Compound 1 with high-density OMSs and LBSs exhibits high CO₂ separation ability.

Luminescent properties of Ag(i)/Cu(i) coordination polymers: crystal structures and high intensity luminescence of a PMMA-doped hybrid material based on a quinoline-2,3-dicarboxylic acid ligand

Preparation, characterization, crystal structure and different luminescent properties of Ag(i)/Cu(i) coordination polymers: stable blue emission, thermochromism and PMMA-doped hybrid material.

Construction of Fe6, Fe8 and Mn8 metallamacrocyclic complexes and magnetic properties

Hexanuclear-based 1 and octanuclear metallamacrocycle-based three-dimensional isostructural framework 2 and 3 have been obtained and characterised. Magnetic susceptibility measurements show that the three complexes display antiferromagnetic couplings.
