A Road Map to Stable, Soluble, Easily Crystallized Pentacene Derivatives

Abstract

[structure: see text] A series of 6,13-disubstituted pentacenes, in which the substituents are functionalized ethyne units, were synthesized and analyzed by X-ray crystallography. The resulting pentacene derivatives were highly soluble and oxidatively stable and exhibited a significant amount of pi-stacking in the crystal.
