Printed electronics aims to realize self-formation of electronic devices under ambient conditions via the printed microfluids that contain such as soluble organic electronic materials or dispersed metal nanoparticles. In this talk, we present our recent investigations for developing advanced printed electronics. The topics include; 1) development of self-organized layered organic semiconductors and of their novel printing method for fabricating high performance printed thin-film transistors, 2) development of printed organic ferroelectric capacitor that presents few volt switching operations, and 3) new printing principle via nanoparticle chemisorption for conductive silver patterning with submicron resolution. We discuss that the explorations are based on outcomes in various fields of materials and nanoscience such as molecular nanotechnology, supramolecular chemistry, solid state and soft matter physics.
