Paper Abstract

A series of 2,3,9,10-tetrasubstituted-6,13-dialkynylpentacenes was synthesized and their properties evaluated. Various alkynes with different substituents were chosen to explore the effects of substitution on acene properties. The addition of alkyl groups to the pentacene 2,3,9,10-positions showed significant effects on the absorption, emission, and redox properties versus the non-alkylated (R = H) materials. The acenes exhibited excellent solubility in numerous solvents, and HOMO energy levels matched well with the work function of gold, an important electrode material. Crystallographic characterization of the methoxymethylene derivative showed it to adopt a 1-dimensional π-stacked arrangement, with good overlap of the aromatic faces.
