Abstract
Charge transport in organic small molecule transistors is strongly connected to the crystal packing of the organic material. Our approach to inducing favorable orientations in organic small molecule systems is evolving, and we are developing new approaches to device enhancement through manipulating the degrees of freedom in both the chromophore and the peripheral solubilizing groups. More recently, we have explored the modification of our materials to move beyond pure charge transport issues, to improve the sensitivity of transistor-based sensors. Here, we will discuss our new observations of improved supramolecular synthons for dense and ordered crystal packing, atomic modifications to improve sensor performance, and rigidification of the entire molecular system to minimize the impact of dynamic motions. I will then discuss briefly the application of these design principles to the development of new molecules for use in organic electrochemical transistors.
