Summary: After the emergence of graphene, the development of semiconducting organic materials with layered structures has become active in the material science field. However, these materials often face poor processability issues. In this study, a new approach is proposed to avoid the processability issue by designing a soluble amorphous network and using heat treatment to develop a flattened organic structure for organic thin-film transistors (TFTs). The fabricated TFTs exhibit good performance in both horizontal and vertical charge transport, suggesting the versatility and usefulness of this approach for the development of organic semiconductors.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
