Bis[Pyrrolyl Ru(II)] Triads: a New Class of Photosensitizers for Metal-Organic Photodynamic Therapy
(2020)A new family of ten dinuclear Ru(II) complexes based on the bis[pyrrolyl Ru(II)] triad scaffold, where two Ru(bpy)2 centers are separated by a variety of organic linkers, was prepared to evaluate the influence of the ... -
BODIPYs with Chalcogenophenes at Boron: Synthesis and Properties. Postprint
(J. Org. Chem., 2023-07-13)Reported herein are the synthesis and characterization of BODIPYs bearing heterocycles at boron. To synthesize this series, various chalcogenophenes (furan, thiophene, selenophene, and tellurophene) were lithiated and then ... -
Bridging and Conformational Control of Porphyrin Units through Non-Traditional Rigid Scaffolds
(Wiley, 2019-11)Connecting two porphyrin units in a rigid linear fashion, without any undesired electron delocalization or communication between the chromophores, remains a synthetic challenge. Herein, a broad library of functionally ... -
Bridging and Conformational Control of Porphyrin Units through Non-Traditional Rigid Scaffolds
(2019-11-07)Connecting two porphyrin units in a rigid linear fashion, without any undesired electron delocalization or communication between the chromophores, remains a synthetic challenge. Herein, a broad library of functionally ... -
A calorimetric investigation of the low-temperature phase transition in sodium hydroxide-d.
(1986)The heat capacity of NaOD from 20 to 350 K is reported. An anomaly centered at 153.2 ± 0.1 K (?H = 131.1 ± 0.7 J/mol, ?S = 0.864 ± 0.005 J/K.mol) corresponds to the onset of a low-temp. antiferroelec. phase. This ... -

Chemical Constituents from Stem Bark and Roots of Clausena anisata
(2012-11)Phytochemical investigations on the stem bark and roots of the tropical shrub Clausena anisata led to the isolation and characterization three carbazole alkaloids: girinimbine, murrayamine-A and ekeberginine; two peptide ... -
Chiral molecules containing the pyrrole framework
(2010)This review summarizes strategies by which chiral pyrroles, both simple and complex, have been prepared: strategies include formation of the pyrrolic ring using starting materials appended with chirality, as well as the ... -
Chloride anion transport and copper-mediated DNA cleavage by C-ring functionalized prodigiosenes
(2007)A new class of prodigiosenes with stability-enhancing functionalities appended to the C-ring were found to transport chloride anions through liposomal membranes, as well as to induce copper-mediated DNA cleavage. -
cis-3,5-Cyclohexadiene-1,2-diol derivatives: facial selectivity in their Diels-Alder reactions with ethylenic, acetylenic and azo dienophiles
(2006)The Diels - Alder reactions of maleimide with the acetonide derivative (6a) of cis-3,5-cyclohexadiene-1,2-diol (1a) in various solvents showed facial selectivities ranging from 1 : 1 to 1 : 9. The same derivative 6a reacted ... -
Cl-BODIPYs: a BODIPY class enabling facile beta-substitution
(2012-01)Cl-BODIPYs, synthesized in high yields from dipyrrins under air- and moisture-free conditions, are extremely facile to substitution at boron compared to their corresponding F-BODIPYs, opening up a new route to BODIPYs ... -
Classifying donor strengths of dipyrrinato/aza-dipyrrinato ligands
(2019)A parameter is reported by which to use 13C NMR chemical shifts to measure and predict the donor capabilities of N^N dipyrrinato and aza-dipyrrinato ligands chelating in L^X fashion. The results enable the rationalisation ... -
A Combinatorial Investigation of Fe-Si-Zn Thin Film Negative Electrodes for Li-ion 1 Batteries (Preprint)
(IOP Publishing, 2014-12-04)Thin-film Fe-Si-Zn libraries were investigated as negative electrode materials for Li-ion batteries using combinatorial and high-throughput techniques. X-ray diffraction and electron microprobe measurements were used to ... -
A Combinatorial Investigation of Fe-Si-Zn Thin Film Negative Electrodes for Li-ion 2 Batteries (Preprint)
(IOP Publishing, 2014-11-07)Sodium-ion batteries have the potential to be a low cost, sustainable replacement for lithium-ion batteries in large scale energy storage. The lack of practical negative electrode materials limit the development of Na-ion ... -
Combinatorial Investigations of Ni-Si Negative Electrode Materials for Li-Ion Batteries
(IOPscience, 2015-06-30)Sputtered thin films in the Ni-Si system (0 ≤ x ≤ 0.65 in NixSi1-x) were studied for use as anode materials in Li-ion cells. All compositions were found to be amorphous. The Ni in Ni-Si films was found to suppress the ... -
