New Electronic Topologies in Organic Electronic Materials
Abstract
This research focuses on molecules interacting with magnetic fields to produce useful optical or electrical behavior. The magneto-optical effects are based on processes wherein molecules that have high symmetry and-or extended structures that produce multiple electronic states with the same energy. Applying magnetic fields can change the energies of electronic states and produce an optical signature. Potential applications of these materials are in the detection or even imaging of small magnetic fields associated with the ion movement in brain activity or blood flow. This research program is also interested in materials that have chiral structures, that assemble into structures with different twist sense, which is similar to left- or right-handed threaded bolts. Chirality can be used to organize materials to promote the magnetooptical properties and can give rise to novel electrical transport. This can give rise to selective transport of electrons having a particular spin state in conductive materials. Materials displaying spin-selective transport can be useful in creating more complex types of electrical devices for application in future electronic and data storage devices.
