Synthesis of Chiral Drug Intermediates

The Department of Electronic Chemistry is a new department established in April 1997. Its predecessor, the Department of Electronic Chemistry (Denshi Kagaku Senko) was established in 1973, and after around 20 years was reorganized to form an improved organization with the goal of "creating new fields of study."
This department covers areas from the fundamental principles to the application of chemistry, based on the idea of understanding chemical phenomena in a unified way through the eyes of electrons, from the viewpoint that a chemical reaction is a process of electrons moving.
The Department of Electronic Chemistry has molecular transformation and material energy conversion as Fundamental Chairs, and their fields of study include organic functional chemistry, organic electrochemistry, electron transfer reactions, inorganic solid-state chemistry, and surface science. In addition, the department has the following Cooperative Chairs: molecular photo spectroscopy, organic synthetic chemistry, catalytic chemistry, polymeric materials, biochemistry, and solid-state physical chemistry. Moreover, the Department of Electronic Chemistry is a pacesetting interdisciplinary department which cooperates with external research organizations to provide education and research.
The Department of Electronic Chemistry sets up its curriculum to help students achieve visionary thinking and creativity so that they can play an active role in wide-ranging fields, such as inorganic materials, organic synthesis, polymer chemistry, electronic materials, biochemistry, and energy conversion as well as in the fields of pure chemistry. Moreover, the Department of Electronic Chemistry offers both master and doctoral degrees in either science or engineering depending on the student's choice, one of the distinct characteristics of the department.

A postdoctoral research associate position is available for the synthesis and testing of redox-active small organic molecules for electrical energy storage, such as the quinone/hydroquinone couple used in a flow battery described in [1]. The position is for one year and may be extended for a second year if performance justifies continued funding.

Structure controlled synthesis of single walled carbon nanotubes with nonmagnetic catalyzed plasma cvd and their electronic properties

With Harvard's new approach to aqueous flow battery chemistry, electrical energy is stored through electrochemical redox reactions of small organic molecules, and returned to the grid through the reversal of these reactions. This particular approach has advantages over other flow battery chemistries, including high power density, inexpensive chemicals, energy storage in the form of safer liquids, and inexpensive components. The novelty of the aqueous organic redox approach creates great opportunities for improvement of performance by the design and synthesis of new organic molecules.

This research project is a collaboration between the experimental chemistry group of Prof. Roy Gordon of the Department of Chemistry and Chemical Biology (CCB) and the School of Engineering and Applied Sciences (SEAS), the materials group of Prof. Michael Aziz in SEAS, and the theoretical chemistry group of Prof. Alan Aspuru-Guzik in CCB. In the Gordon lab the researcher who takes this position will synthesize molecules predicted to be advantageous by the Aspuru-Guzik group, and characterize them in collaboration with others in the Gordon and Aziz laboratories. S/he will also characterize the interaction of these molecules and their supporting electrolytes with ion-selective membranes and non-selective porous separators.

Powder of BaCe0.54Zr0.36Y0.1O2.95 (BCZY) was synthesized by a modified sol-gel method. Glycolic acid, citric acid, triethylenetetramine (TETA), nitriloacetic acid (NTA) and ethylenediaminetetracetic acid (EDTA) were used as chelating agents. The role of chelating agents on the phase formation and thermal characteristics of ceramic powders has been investigated. The obtained powders were characterized by employing thermogravimetric analysis (TGA), Fourier transform Infrared (FTIR) spectroscopy and X-ray diffractometer (XRD). Thermal decomposition of the samples was about to complete at ≈ 950°C based on the TG-DTG profile. FTIR spectra detected the trace of carbonate residue in all samples and XRD pattern showed high intensity of perovskite phase formed for sample prepared with TETA. It was found that TETA is the best chelating agent with metal nitrate salts as precursors to produce a pure phase of BCZY powders at 1100 °C.

Synthesis and characterization of diamond-like carbon thin films prepared by pulsed laser deposition method

We are fascinated by the diversity of effects that ligands can have to instigate new properties in transition metal complexes and we are therefore strongly interested in designing and developing new ligands that impart specific properties to the metal center. One of these ligands are triazolylidenes, a mesoionic carbene that we discovered in 2008. This ligand offers various opportunities for catalysis, including strong electron donor properties, a high synthetic flexibility that allows for a wide variety of functional and chelating groups to be incorporated, and a high polarity, which imparts solubility in water and other polar media. We have obtained evidence in a variety of catalytic reactions like nickel-catalysed hydrosilylation, ruthenium-catalyzed alcohol dehydrogenation, or iridium-catalyzed water oxidation, that the triazolylidene ligand scaffold is controlling the reactivity of the coordinated metal center. Because of the synthetic versatility and the easy accessibility of the ligand, tailoring of the ligand properties is straightforward and we have disclosed improved catalytic activity by ligand tuning. More recently, we have discovered a straightforward approach to functionalize the ligand on the complex as opposed to the more traditional approach of preparing a functional ligand and only then install the metal center. This approach gives rapid access to a large diversity of functionalized ligands in a very last step, and to ligand scaffolds that are not accessible by traditional routes.

Electrochemical routes for industrial synthesis

Ab initio modeling, materials synthesis, and leading-edge experimentation are all utilized to understand the behavior and performance of materials and devices at the micro- and nanoscale. Engineered defects and nanostructured materials are utilized to understand the electrical, thermal, electrochemical, magnetic, optical, and chemical properties of a wide range of materials and films. Fundamental materials properties such as stress, luminescence, fluorescence, dissipation, quantum efficiency and dynamic lifetimes are of interest, as well as materials behavior at high temperature and/or pressure and in high strength electric and/or magnetic fields.

Synthesis and Electrochemistry of Nanocrystalline Iron …

Inspired by the tautomeric relationship of imidazole and N-heterocyclic carbenes, we have been intrigued about the implications of such carbenes in metalloenzymes. Enzymes are the machinery of all biological transformations, and provide inspiration for designing artificial catalysts. New insights into the mode of action of enzymes is therefore instrumental for developing more competent synthetic catalysts as well as for better understanding natural systems. In collaboration with F. Paradisi (U Nottingham), we have begun to explore carbene binding to metalloenzymes. We have been focusing on blue copper proteins such as azurin and specific mutants of azurin to investigate the possibility of carbene bonding to the copper center, and to evaluate the effect that such bonding entails. While azurin is predominantly involved in electron transfer processes through reversible copper(II) reduction and oxidation, other blue copper proteins are catalytically active in redox transformations of substrates. Hence, these enzymes provide an attractive probe to explore the relevance of carbene bonding on the catalytic performance of the enzyme.
