SUMMARY
Organic electronics and optoelectronics are newly emerging fields of science and technology that cover chemistry, physics, and materials science. Electronic and optoelectronic devices using organic materials are attractive because of the materials characteristics, potentially low cost, and capability of large-area, flexible device fabrication. Such devices as OLEDs, OPVs, and OFETs involve charge transport as a main process in their operation processes, and therefore, require high-performance charge-transporting materials. This review article focuses on charge-transporting materials for use in OLEDs, OPVs, and OFETs. We have tried to arrange the charge-transporting materials in order by classifying them on the basis of their molecular structures. Molecular design concepts for charge-transporting materials and their charge-transport properties are discussed.http://dx.doi.org/10.5755/j01.ms.17.4.767
