Abstract

Three stereoisomers of a diketopyrrolopyrrolecontaining conjugated molecule are separated and identified to investigate the effects of stereoisomerism on the crystallization behavior and optoelectrical properties of the material. The investigation by Thuc-Quyen Nguyen and co-workers on page 3645 reveals useful hints to address two primary experimental challenges for complicated conjugated molecules, i.e., how to grow well-defined single crystals, and the polymorphism of crystal structures.
