When extreme flexibility is required for electronic devices, molecular solids of small molevules are prone to brittle fracture, while inorganic solids, whose basic backbone is a covalent bond network, are prone to dangling bonds and defects. In contrast, one-dimensional materials such as carbon nanotubes and polymers have the great advantage that their mechanical strength as molecules is secured by one-dimensional covalent bonds, while the bonding between neighboring molecules is based on Wander Waals forces, allowing stress to be dispersed by intermolecular sliding and preventing defects from forming even under strong bending. This has the great advantage that defects do not occur even under strong bending. In this presentation, examples of thermoelectric, solar cell, and transistor research aiming at super-flexible electronics will be presented.
