Professional Experience

1986 - 1987Alexander von Humboldt Fellowship, Universitat Frankfurt
One of the most exciting topics in modern chemistry is the possibility of creating nano-devices such as molecular computers. Already there are molecules which can operate as transistors, resistors, diodes, motors and molecular switches which may be activated by temperature, pressure or electro-magnetic radiation. Tying these devices together will require some sort of molecular wires. Many groups worldwide are working on this problem. It is necessary to prepare some sort of polymer and this usually results in making large numbers of molecules having different lengths controlled by a binomial distribution (Bell curve). Our approach allows the preparation of long wires of uniform length and in addition allows us to make wires which are bent to any desired angle. This project requires students to be skilled in both organic and inorganic synthesis. Other students are studying the properties of these wires using electronic and infrared spectroscopy, nmr and mass spectrometry techniques and electrochemistry. Several of our molecules are candidates for collaborative studies with Professor Leblanc's group in Langmuir-Blodgett techniques and scanning tunneling microscopy experiments.
