Hexathiapentacene:Structure,Molecular Packing,and Thin-Film Transistors

摘要

The past decade witnessed a tremendous development of organic molecules for use in electronic and optoelectronic devices.Oligo-acenes,tetrathiafulvalene (TTF),and their derivatives have been extensively studied as fundamental building blocks for organic electronics.As an example of oligo-acenes,pentacene has led organic semiconductors with the highest field-effect mobility in thin film transistors.Most recently,several neutral TTF derivatives have been applied as organic semiconductors in field-effect transistors.The molecular packing of TTF derivatives is characteristic of pi-pi interactions and the S...S interactions,both of which are responsible for intermolecular charge transport.
