Effect of molecular packing on corannulene-based materials electroluminescence


Zoppi, L; Martin-Samos, L; Baldridge, K K (2011). Effect of molecular packing on corannulene-based materials electroluminescence. Journal of the American Chemical Society, 133(35):14002-14009.

Abstract

The present investigation reports for the first time a detailed theoretical analysis of the optical absorption spectra of corannulene-based materials using state-of-the-art first-principles many-body GW-BSE theory. The study specifically addresses the nature of optical excitations for predictions regarding suitability for device fabrication. The well-defined structure–correlation relationship in functionalized corannulenes is used in a focused investigation of the predicted optoelectronic properties in both the isolated state and bulk crystals. The findings suggest that the excitonic properties are strongly dependent on the specific substituent group as well as the crystalline arrangement. Arylethynyl-substituted corannulene derivatives are shown to be the most suitable for device purposes.
