Recently, the +2 formal oxidation state in soluble molecular complexes for lanthanides (La-Nd, Sm-Lu) and actinides (Th and U) has been discovered [W. J. Evans, et al., J. Am. Chem. Soc., 2011, 133, 15914; J. Am. Chem. Soc., 2012,...

Tuning Mixed-Valent Eu(2+) /Eu(3+) in Strontium Formate Frameworks for Multichannel Photoluminescence.

Chemistry (Weinheim an der Bergstrasse, Germany)

Liu W, Liu L, Wang Y, Chen L, McLeod JA, Yang L, Zhao J, Liu Z, Diwu J, Chai Z, Albrecht-Schmitt TE, Liu G, Wang S.
PMID: 27305606
Chemistry. 2016 Aug 01;22(32):11170-5. doi: 10.1002/chem.201602621. Epub 2016 Jun 30.

Cooperative performance of mixed-valent Eu(2+) /Eu(3+) in single-compound phosphors offers significant advantages in color rendering and luminescence efficiency, but their synthesis is challenging because of Eu(2+) oxidation. Using the tunable nature of the metal-ion nodes in metal-organic frameworks (MOFs),...

Downregulation of P16 promotes cigarette smoke extract-induced vascular smooth muscle cell proliferation via preventing G1/S phase transition.

Experimental and therapeutic medicine

Guo T, Chai X, Liu Q, Peng W, Peng Z, Cai Y.

The limited long-term hydrolytic stability of rapidly emerging 3D-extended framework materials (MOFs, COFs, MOPs, etc.) is still one of major barriers for their practical applications as new solid-state electrolytes in fuel cells. To obtain hydrolytically stable materials, two H2...

A mesoporous cationic thorium-organic framework that rapidly traps anionic persistent organic pollutants.

Nature communications

Li Y, Yang Z, Wang Y, Bai Z, Zheng T, Dai X, Liu S, Gui D, Liu W, Chen M, Chen L, Diwu J, Zhu L, Zhou R, Chai Z, Albrecht-Schmitt TE, Wang S.
