Combining electronic and steric effects for highly stable unsymmetric pentacenes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhang J, Pawle RH, Haas TE, Thomas SW.
PMID: 24623650
Chemistry. 2014 May 12;20(20):5880-4. doi: 10.1002/chem.201402003. Epub 2014 Mar 13.

This paper describes the reactivity of unsymmetrically substituted pentacenes to photochemical oxidation. Acenes in general, and pentacenes in particular, are a key family of compounds for a variety of organic electronics applications. The instability of many pentacene derivatives, particularly...

Int J Ophthalmol. 2013;6(1):8-14. doi: 10.3980/j.issn.2222-3959.2013.01.02. Epub 2013 Feb 18.

AIM: To investigate the role of Rho-associated protein kinase (ROCK) inhibitor, Y27632, in mediating the production of extracellular matrix (ECM) components including fibronectin, matrix metallo-proteinase-2 (MMP-2) and type I collagen as induced by connective tissue growth factor (CTGF) or...

Photocatalytic hydrogen generation enhanced by band gap narrowing and improved charge carrier mobility in AgTaO3 by compensated co-doping.

Physical chemistry chemical physics : PCCP

Li M, Zhang J, Dang W, Cushing SK, Guo D, Wu N, Yin P.
PMID: 23995011
Phys Chem Chem Phys. 2013 Oct 14;15(38):16220-6. doi: 10.1039/c3cp51902c. Epub 2013 Sep 02.

The correlation of the electronic band structure with the photocatalytic activity of AgTaO3 has been studied by simulation and experiments. Doping wide band gap oxide semiconductors usually introduces discrete mid-gap states, which extends the light absorption but has limited...

Triangular Ag-Pd alloy nanoprisms: rational synthesis with high-efficiency for electrocatalytic oxygen reduction.

Nanoscale

Xu L, Luo Z, Fan Z, Zhang X, Tan C, Li H, Zhang H, Xue C, Della D.
