Abstract:

In this talk, I will describe collaborative studies on materials with the goal of understanding how the systematic variation of chemical structure of chiral organic and hybrid semiconductor systems impacts the chiral nature of the ordering in the material over multiple length scales, the CISS effect, and chirality-related optical and opto-electronic properties. Chirality has been introduced to the materials using both covalent (incorporation of chiral centers into molecular semiconductors and into polymeric semiconductors at varying concentrations) and noncovalent interactions (e.g., between achiral semiconductor molecules or polymers and chiral additives鈥攂oth small molecular and polymeric鈥攐r chiral counter ions introduced using redox dopants).听
