Supramolecular organic semiconducting nanostructure: self-assembly properties and surface selective bonding:
π-conjugated organic semiconductors are regarded as a promising class of materials that finds application in a wide range of electronic and optoelectronic devices including light emitting diodes, photovoltaics and transistors not only due to their intriguing advanced electronic and optical properties, but also the possibility for low cost solution processing in large area applications and on flexible substrates. Since the performance of the organic semiconductors is strongly dependent on their intermolecular organization, one main challenge in the field is to create monodomain crystalline structures for achieving high charge mobility through coherent charge transport. The study of single organic crystals, in which grain boundaries are eliminated and concentration of charge traps is minimized, is important for the fundamental understanding of the intrinsic electrical property the semiconductor. In our research, we introduce the supramolecular self-assembly concept to the design and synthesis of a series of discotic π-conjugated molecules that can be self-assembled into 1-D nanostructure in solution and study their self-assembly properties. Furthermore, we utilize a micro-patterned self-assembled monolayer as a nucleation template to selectively growth the crystal on the surface. Our ultimate goal is selectively self-assemble the supramolecular structures between metal electrodes and study their electrical property through a field-effect transistor configuration. We also can use the supramolecular electronics device as a transducer for chemical and bio sensing.
