Abstract

In this letter, the top-down and bottom-up segmentations were integrated together to realize high-performance organic devices and circuits. By combining photolithography with in situ polymerization, high conductive polypyrrole was patterned and used as electrodes for organic field-effect transistors (OFETs). With pentacene as P-type organic semiconductor and N,N´-bis (n-octyl)-Dicyanop-erylene-3,4:9,10-is (dicarboximide) (PDI-8CN2)/copper hexadecafluorophthalocyanine (CuPcF16) as N-type ones, both P-type and N-type OFETs exhibit excellent stability. Air-stable complementary inverters with the highest gain of 16.1 were realized. The results showed that the method was suitable for the fabrication of organic circuits.
