Single-Crystal Organic Nanowires of Copper-Tetracyanoquino-dimethane:Synthesis,Patterning,Characterization,and Device Applications

摘要

Single-crystal,one-dimensional semiconductor nanostruc-tures are very important building blocks for nanoscale optical and electronic devices.Currently,much attention is focused on inorganic materials,such as carbon nanotubes and inorganic oxide nanowires,whose properties endow them with considerable potential.Fewer studies have been performed on organic semiconductor nanowires,despite their widespread development for inexpensive organic thin-film optoelectronic devices.Organic semiconducting materials comprised of smaller molecules normally have conjugated structures.As a consequence of their diversity,tailorability,multifunctionality,and ease in forming very highly ordered crystals,it is highly desirable to synthesize single-crystal organic semiconducting nanowires from small molecular compounds,which could serve as low-cost,high-performance building blocks for the next-generation lightweight displays and for applications in information storage.
