Professor Michl's group works in physical organic chemistry, a combination of synthesis of organic and organometallic (both main group and transition metal) compounds with an investigation of their properties by physical, mechanistic, and computational methods. This ranges from photochemical reactions to nanotechnology.
The areas of most interest at this time are (i) molecular electronics of the traditional (electron motion) and non traditional (electrostatic charge motion) types, (ii) photochemical reaction mechanisms, (iii) nature of electronic excitation in saturated compounds, and (iv) new structures based on carborane anions radicals and reactions.
In traditional single molecule electronics we are looking at the use of single molecules as electronic components (diode, transistor). In non traditional molecular electronics we are exploiting the concept of dipolar molecular rotors mounted on surfaces and driven by rotating electric field or by fluid flow. In an attempt to position such rotors in a regular two dimensional pattern, we are developing synthetic approaches to molecules that look like a tennis net or chicken wire.
Photochemical mechanisms deal with issues such as the nature of "twisted internal charge transfer states", heavy atom effects on intersystem crossing, and harvesting of solar energy. The saturated compounds whose electronic excitation we are examining as a function of chain conformation are peralkylated oligosilanes.
The new carborane and related structures involve some of the strongest acids and strongest oxidants known. We are attempting to prepare bulk species otherwise known only in the gas phase. This is very fundamental science but it also has some immediate applications for polymer lithium battery electrolytes and fuel cell membranes.
The research group has about two dozen members with roughly equal numbers of post-doctoral, graduate, and undergraduate students. After the first year of study, the graduate students are supported by research assistantships or their own scholarships. The group is quite international. Many of the post docs are from various European and other foreign countries, and each graduate student presents results at one or more conferences abroad; many work on their projects for weeks or months in foreign laboratories. The group social life includes enjoyment of Colorado mountains during long-weekend group trips on skis or hiking and camping.
