Paper Abstract

We have studied alkyl-substituted pentacene derivatives for solution-processing. By incorporation of substituent(s), enhancement of solubility depending on substituted position(s) and substituent(s) was confirmed. Solution-processed films of the derivatives showed highly oriented crystals with herringbone structure. This indicates that molecular aggregation and electronic structure have been preserved after the substitution as expected from molecular design. Thinfilm transistors of the derivatives exhibited large carrier mobility above 1cm2/Vs.
