``Organic Molecules in Electronic Devices: Transistors, Diodes and Solar Cells''


Linearly-fused aromatic molecules exhibit the best performance in several organic electronics applications. Unfortunately, most of these rigid compounds suffer from poor solubility, precluding the use of solvent-based methods for deposition in organic devices. By carefully considering the effect of substitution on intermolecular order and self-assembly, it is possible to significantly increase both the solubility and stability of these condensed aromatics, while simultaneously maintaining or even improving the electronic properties that make these materials ideal for device applications. My talk will cover the modification of a series of acenes and heteroacenes for use in field-effect transistors, light-emitting diodes and solar cells, and the wealth of structure-property relationships we have been able to derive from the performance of numerous materials in these devices.

Refreshments will be served in CP 155 at 3:15 PM
