The Hairpin Furans: Easily Prepared Hybrids of Helicenes and Twisted Acenes.

Angewandte Chemie (International ed. in English)

Geng X, Donahue JP, Mague JT, Pascal RA.
PMID: 26403622
Angew Chem Int Ed Engl. 2015 Nov 16;54(47):13957-60. doi: 10.1002/anie.201506792. Epub 2015 Sep 25.

The thermal reaction of a cyclopentadienone with 6,6'-dimethoxy-5,5'-binaphthoquinone gives, in a single step, a molecular ribbon consisting of two twisted aromatic systems fused to a heteropentahelicene. Such molecules constitute a new class of chiral polycyclic aromatic compounds, the "hairpin...

A study on the optics of copper indium gallium (di)selenide (CIGS) solar cells with ultra-thin absorber layers.

Optics express

Xu M, Wachters AJ, van Deelen J, Mourad MC, Buskens PJ.
PMID: 24922252
Opt Express. 2014 Mar 10;22:A425-37. doi: 10.1364/OE.22.00A425.

We present a systematic study of the effect of variation of the zinc oxide (ZnO) and copper indium gallium (di)selenide (CIGS) layer thickness on the absorption characteristics of CIGS solar cells using a simulation program based on finite element...

Syntheses, Crystal Structures, and NLO Properties of New Chiral Inorganic Chromophores for Second-Harmonic Generation.

Inorganic chemistry

Lenoble G, Lacroix PG, Daran JC, Di Bella S, Nakatani K.
PMID: 11670370
Inorg Chem. 1998 May 04;37(9):2158-2165. doi: 10.1021/ic970481w.

A new chiral ligand (H(2)L) based on the condensation of diaminocyclohexane and 4-(diethylamino)salicylaldehyde is reported along with its nickel(II) and manganese(III) complexes. These compounds all crystallize in noncentrosymmetric space groups. Crystal data are as follows. For the ligand (C(28)H(40)N(4)O(2)):...

Directed Evolution and Biocatalysis.

Angewandte Chemie (International ed. in English)

Powell KA, Ramer SW, Del Cardayré SB, Stemmer WP, Tobin MB, Longchamp PF, Huisman GW.
PMID: 12404465
Angew Chem Int Ed Engl. 2001 Nov 05;40(21):3948-3959. doi: 10.1002/1521-3773(20011105)40:21<3948::aid-anie3948>3.0.co;2-n.

This review describes the current state of biocatalysis in the chemical industry. Although we recognize the advantages of chemical approaches, we suggest that the use of biological catalysis is about to expand dramatically because of the recent developments in...

A Nearly Linear Single Hydroxo Bridge. Synthesis, Structure, and Magnetic Susceptibility of (&mgr;-Hydroxo)bis((tetraphenylporphinato)manganese(III)) Perchlorate.

Inorganic chemistry

Cheng B, Fries PH, Marchon JC, Scheidt WR.
PMID: 11666280
Inorg Chem. 1996 Feb 14;35(4):1024-1032. doi: 10.1021/ic951041c.

The synthesis, X-ray structure, and magnetic susceptibility characterization of a hydroxo-bridged complex, (&mgr;-hydroxo)bis((tetraphenylporphinato)manganese(III)) perchlorate, {[Mn-(TPP)](2)(OH)}ClO(4), are described. The complex is readily prepared by a controlled hydrolysis of monomeric diaquo(tetraphenylporphinato)manganese(III) perchlorate. Interestingly, the bridging hydroxo complex appears to be more...

Highly efficient P-N nickel(II) complexes for the dimerisation of ethylene.

Chemical communications (Cambridge, England)

Buchard A, Auffrant A, Klemps C, Vu-Do L, Boubekeur L, Goff XF, Floch PL.
PMID: 17406687
Chem Commun (Camb). 2007 Apr 21;(15):1502-4. doi: 10.1039/b618401d. Epub 2007 Feb 05.

New P-N ligands featuring a phosphino group and an iminophosphorane moiety were successfully employed in the nickel-catalysed dimerisation of ethylene.

Configurationally stable longitudinally twisted polycyclic aromatic compounds.

Journal of the American Chemical Society

Walters RS, Kraml CM, Byrne N, Ho DM, Qin Q, Coughlin FJ, Bernhard S, Pascal RA.

J Am Chem Soc. 2008 Dec 03;130(48):16435-41. doi: 10.1021/ja806958x.

Two strategies for the synthesis of configurationally stable twisted polycyclic aromatic compounds (PACs) were pursued. The first approach employed dissymmetrically positioned 1-naphthyl substituents to bias the direction of twist in highly substituted PACs. 2,3-Bis(1-naphthyl)-1,4-diphenyltriphenylene (7) was prepared, and its...

Sparse canonical methods for biological data integration: application to a cross-platform study.

BMC bioinformatics

PMID: 19171069
BMC Bioinformatics. 2009 Jan 26;10:34. doi: 10.1186/1471-2105-10-34.

BACKGROUND: In the context of systems biology, few sparse approaches have been proposed so far to integrate several data sets. It is however an important and fundamental issue that will be widely encountered in post genomic studies, when simultaneously...

Accelerated luminophore discovery through combinatorial synthesis.

Journal of the American Chemical Society

Lowry MS, Hudson WR, Pascal RA, Bernhard S.
PMID: 15506778
J Am Chem Soc. 2004 Nov 03;126(43):14129-35. doi: 10.1021/ja047156+.

A method for accelerating the discovery of ionic luminophores using combinatorial techniques is reported. The photophysical properties of the resulting transition-metal-based chromophores were compared against a series of analogous, traditionally prepared species. The strong overlap between these two sets...
