Abstract

Focusing on the bottleneck of molecularly engineered organic semiconductors, a breakthrough is made to tune the electronic properties of organic semiconductors from p-type to n-type by using fluorinated metal phthalocyanines as examples. The experimentally observed p-type to n-type transition characteristics of single-crystal field-effect devices result from a combination of extrinsic and intrinsic properties of materials with different fluoridation substitution.
