The synthesis of a rigid, planar H-type anthracene derivative is described. Single-crystalline ribbons at micro- and nanometer sizes can be controllably produced and transistors based on an individual ribbon can be fabricated in situ through a newly developed "organic ribbon mask" method, in which the channel length of the transistors can be easily scaled down to sub-micrometer level.
Keywords: anthracene derivatives; microribbons; nanoribbons; single crystals; transistors.
