Research Description
Inorganic and Organometallic Chemistry
Reactivity of Transition Metal-Carbon Multiple Bonds
A major project of my group is concerned with the reactivity of metal-carbon multiple bonds. Our work focuses on transition metal alkylidyne complexes, i. e., compounds containing metal-carbon triple bonds. We studied coupling reactions of alkylidyne ligands with other terminal ligands such as carbonyl, isocyanide, and thiocarbonyl ligands. The coupling of two alkylidyne ligands was also demonstrated. Coupling reactions of alkylidyne ligands with other ligands such as alkylidene, imido, oxo, alkyl, aryl, alkynyl ligands will be explored. In this work, we are primarily interested in the fundamental aspects of the bond-forming steps. We investigated reactions of alkylidyne metal complexes with alkenes, alkynes and other unsaturated organic substrates. These reactions may be useful for the construction of larger organic systems within the coordination sphere of transition metal centers.
Metal-Carbon Multiple Bonds as Functional Components in Molecular Materials
Metal-carbon triple bonds provide a means of strong electronic coupling between metal centers and organic π systems. This feature and the presence of low-energy metal-to-alkylidyne charge transfer transitions make metal-carbon triple bonds promising as components in molecular materials. Furthermore, metal-carbon triple bonds are thermally rather stable entities, and reliable synthetic methods are available to fine-tune the electronic properties of metal alkylidyne complexes. Several functionalized tungsten alkylidyne complexes of the Fischer-type have been designed for the study of the following aspects: nonlinear optical properties, photo-induced directional electron transfer, and photo-induced energy transfer.
Synthesis of Molecular Solid-State Materials by the Self-Assembly of Stable Transition Metal Complex Building Blocks
We are working on the synthesis of molecular materials based on the assembly of geometrically rigid transition metal complex building blocks. The synthetic strategy is based on bi- (or multi-) functional ligands, whereby one functionality is a strongly ligating site that forms stable transition metal complex building blocks of defined geometry and size. The other function is a site capable of weak interactions, such as a weakly coordinating site or a hydrogen bonding site. The building blocks are interconnected in a geometrically defined manner via the weak interaction sites. The goal is to achieve control over the supramolecular structures and physical properties on the new materials via the nature of these transition metal complex building blocks. Thus, by proper choice of transition metal centers (electron configuration and coordination geometry) and spacer ligands (length, steric and electronic properties) it may be possible to determine the dimensions of the new materials and influence their electronic properties. Presently, we are focusing on transition metal complexes of bifunctional isocyanides as the building blocks.
Molecular Single-Electron Devices
Our earlier work on the electronic coupling between tungsten alkylidyne and other transition metal complex fragments across oligophenyleneethynylene bridges connects to our current efforts on molecular single-electron devices. This project started as a collaboration with Prof. K. K. Likharev in the Department of Physics and Astronomy. It led to the design of molecular versions of single-electron devices, the chemical synthesis of simple model compounds for the measurement of their molecular electrical conductance in a prototypical crossbar network, and the theoretical study of a system with specific molecular components.
