Abstract

<p>The ideal process for development of organic semiconductors is a cycle composed of theoretical molecular simulations of the performance, organic synthesis, and device characterization. In this work, focusing on alkyl-substituted tetrathienonaphthalene derivatives as a candidate of organic semiconductor, we predicted their hole mobility in the amorphous-solid state by original simulation based on quantum mechanics/molecular mechanics method. Next, we actually synthesized them, fabricated their organic field-effect transistors, and measured their hole mobility. As a result, theoretical and experimental hole mobilities show a good correlation, proving that the cycle triggered by theoretical molecular simulation is efficient methodology for research and development of organic semiconductors.</p>
