Research Overview

 

Chemistry and Dynamics in the Condensed Phase

Professor Waldeck's research program uses methods of spectroscopy, electrochemistry, and microscopy to investigate primary processes in the condensed phase, which includes liquids, solids and liquid/solid interfaces. Current themes of his research are the fundamental understanding of the chiral induced spin selectivity (CISS) effect and its role in electron transfer reactions and electron transport in supramolecular structures.

Solution Studies

His research program studies electron transfer processes experimentally in order to directly evaluate and improve theoretical models. Currently, his group is investigating how the electron transfer in semiconductor nanoparticle assemblies depends on energetic, geometric, and electrostatic features of the assemblies.  Other efforts are studying electron transfer between semiconductor nanoparticles and conjugated polymers and how it depends on the energetic, electrostatic, and chirality of the constituents. A major goal of these studies is to understand how the structural and energetic hierarchy of nanometer scale assemblies can be manipulated to control electron transfer.

Interfacial Charge Transfer

This effort probes charge transfer through monolayers and individual molecules by electrochemical and/or conducting probe methods. Previous work has used electrochemical studies to elucidate how the molecular properties (e.g., electronic character, chirality, and the nature of the molecule-electrode linkage) affect the observed tunneling barriers and molecular conductivities.  Current work is investigating how to manipulate the electronic and chemical nature of monolayer films to enhance the electronic interaction between a redox moiety and the electrode, with a particular focus on better understanding how to ‘wire’ biomolecules (proteins and oligonucleotides) to electrodes.

Chiral Induced Spin Selectivity (CISS)

As electrons move through a chiral molecule they generate an effective magnetic field, B, that acts on the electrons’ intrinsic magnetic moment, and this creates a preference for the transmission of one electron spin direction over the other.   Waldeck’s group is exploring fundamental features of the CISS effect and examining its application for enantioselectivity in chemical reactions and chemical separations.
