Strategic modulation of the photonic properties of conjugated organometallic Pt–Ir polymers exhibiting hybrid CT-excited states
(2014) - Journal article,
Polymer 6, ([trans-Pt(PBu3)2(C≡C)2]-[Ir(dFMeppy)2(N^N)](PF6))n, (([Pt]-[Ir](PF6))n; N^N = 5,5′-disubstituted-2,2′-bipyridyl; dFMeppy = 2-(2,4-difluoro-phenyl)-5-methylpyridine) is prepared along with model compounds. These ...
The X-ray structure of 4-aminobenzyl alcohol (4-aminophenylmethanol)
(2018-11-02) - Journal article,
A second polymorph of 4-aminobenzyl alcohol [orthorhombic, a = 8.95051(15), b = 5.8248(1), c = 12.1645(2) Å, space group Pna21] shows a "herringbone" structure with stacks of hydrogen-bonded molecules when viewed down the b-axis.
Morphological, chemical, and electronic changes of the conjugated polymer PTB7 with thermal annealing
(2018-04-27) - Journal article,
There is considerable interest in improving the performance of organic optoelectronic devices through processing techniques. Here, we study the effect of high-temperature annealing on the properties of the semiconducting ...
Yeast three-hybrid screen identifies TgBRADIN/GRA24 as a negative regulator of Toxoplasma gondii bradyzoite differentiation
(2015-03-19) - Journal article,
Differentiation of the protozoan parasite Toxoplasma gondii into its latent bradyzoite stage is a key event in the parasite’s life cycle. Compound 2 is an imidazopyridine that was previously shown to inhibit the parasite ...
New irreversible α-ʟ-iduronidase inhibitors and activity-based probes
(2018-11-26) - Journal article,
Cyclophellitol aziridines are potent irreversible inhibitors of retaining glycosidases and versatile intermediates in the synthesis of activity‐based glycosidase probes (ABPs). Direct 3‐amino‐2‐(trifluoromethyl)quinazoli ...
50-1: Invited paper: Recent advances in measuring and understanding the influence of molecular alignment on the light extraction efficiency of OLEDs
(2017) - Journal item,
We review recent progress in controlling the alignment of the transition dipole moment of electroluminescent molecules to maximize the light extraction efficiency in OLEDs. Particular focus devoted to ways of measuring ...
All-cis 1,2,3,4,5,6-hexafluorocyclohexane is a facially polarised cyclohexane
(2015-04) - Journal article,
The highest-energy stereoisomer of 1,2,3,4,5,6-hexafluorocyclohexane, in which all of the fluorines are ‘up’, is prepared in a 12-step protocol. The molecule adopts a classic chair conformation with alternate C–F bonds ...
Linear Eyring plots conceal a change in rate-limiting step in an enzyme reaction
(2018-12-11) - Journal article,
The temperature dependence of psychrophilic and mesophilic (R)-3-hydroxybutyrate dehydrogenase steady-state rates yields nonlinear and linear Eyring plots, respectively. Solvent viscosity effects and multiple- and ...
Mechanistic study of Ru-NHC-catalyzed hydrodefluorination of fluoropyridines : the influence of the NHC on the regioselectivity of C–F activation and chemoselectivity of C–F versus C–H bond cleavage
(2015-02-06) - Journal article,
We describe a combined experimental and computational study into the scope, regioselectivity, and mechanism of the catalytic hydrodefluorination (HDF) of fluoropyridines, C5F5?xHxN (x = 0?2), at two Ru(NHC)(PPh3)2(CO)H2 ...
