General Description 1,3,8,10(2 H ,9 H )-Tetraone, 2,9-bis(2-phenylethyl)anthra[2,1,9- def :6,5,10- d′e′f′ ]diisoquinoline (PEPTC) is an n-type small molecular organic semiconducting material. They are most commonly used in organic thin film transistors (OTFT) and also in solution processed organic photovoltaic cells (OPV). They have a well-defined structure and do not show any molecular weight dependence, leading to high purity and ease of processability. Application Used as an n-type semiconducting material in organic and printed electronics.
