Principal Research Interests

  • Inorganic Synthesis
  • (Supra)molecular Materials
  • Smart Molecules

I am interested in research challenges related to current problems of technological and environmental significance. Central to my effort is the concept of engineered complexity where modern computational methods are used to guide the combination of well defined components into functional smart molecules and materials. My research program has three major objectives: A) use light to enhance the reactivity of transition-metal complexes through photoswitchable ligands, B) use molecular recognition to drive the self-assembly of molecular electronics, and C) achieve conductivity in porous materials mediated by the efficient electronic overlap between p-block elements and organic bridges.

A) Redox-active unsaturated early transition metal complexes are capable of activating small molecule substrates. The resulting species are often thermodynamically stable products. We will be using photoswitchable ligands to modulate the redox properties of coordination complexes. These smart molecules will be used to drive the transformation of ubiquitous small molecules like CO2 into value-added products.

B) Secondary bonding interactions (SBIs) are structure directing attractive interactions involving heavy p-block atoms. We will prepare a series of supramolecular pairs that selectively self-assemble through SBIs. These sets of molecules will be the inorganic equivalent to DNA base pairs. We will use these pairs to direct the self-assembly of supramolecular diodes and wires, providing a method – supramolecular synthesis – for preparing integrated molecular electronics.

C) A conductive porous framework would have many applications. MOFs, a promising class of materials, are most often characterized by coordination bonds between hard anions and hard cations. The result is poor orbital overlap causing the electrons to be ‘trapped' at the metal nodes. We will utilize the more favorable energetic overlap between p-block elements in the design of network solids by using p-block clusters as nodes in frameworks. These frameworks will be considered for applications such as electrodes for batteries, fuel cells, capacitors, sensors and molecular wires.

Opportunities to Acquire Expertise

Students in my group will acquire a broad spectrum of practical skills including inorganic synthesis (using p-block and d-block elements), organic synthesis (through ligand design), structure determination through spectroscopic and diffraction techniques, and modern computational methods. As your project progresses you will have ample opportunity to learn and apply specialized techniques either independently or through collaborative efforts.
