Abstract
The present invention discloses a soluble and air-stable perylene diimide (PDI) derivative to function as an N-type organic semiconductor material. In the PDI derivative of the present invention, the core thereof is substituted by electron withdrawing groups, and the side chains thereof are substituted by benzene functional groups, whereby are promoted the solubility and air-stability of the molecule. The PDI derivative of the present invention can be used to fabricate an organic semiconductor element via a soluble process at a low temperature and under an atmospheric environment.
