Understanding the Relationships Between the Structural, Optical, Electronic and Spintronics Properties of Chiral Organic Semiconducting and Conducting Materials
Abstract
The chiral-induced spin-selectivity (CISS) effect is becoming increasingly recognized and exploited, but the fundamental structure-property relations underlying this effect and its relation to other phenomena found in chiral materials are not yet well understood. This program aims to study how systematic variation of chemical structure of chiral systems at multiple length scales impacts CISS, circular dichroism (CD), and other novel optical, spintronic, and opto-electronic properties of chiral organic (semi)conductors. Our approach involves a feedback loop of synthesis, measurement, and device work to answer a range of research questions about how structure of chiral materials relates to their optical and optoelectronic properties. Topics that will be explored include- the impact of varying the pitch and radius of helical chiral materials properties; the impact of spin-orbit coupling; tuning the length scale over which chiral ordering in maintained; and understanding how the spin-dependent behavior of conductive (doped) materials compare to that of undoped materials.
