Synthesis of acenes and hydroxy-acenes

Abstract

A method comprising reducing an acenequinone to form an acenepolyhydrodiol by exposing the acenequinone to a reducing environment comprising an alkoxyaluminate.

Description

TECHNICAL FIELD OF THE INVENTION [0001] The present invention is directed, in general, to the synthesis of organic molecules used in electrical devices, compositions comprising such molecules and the manufacture of electronic devices using such molecules. BACKGROUND OF THE INVENTION [0002] There is great interest in the use of aromatic organic molecules, such as acenes, to form semiconductive films in electronic devices as an alternative to conventional inorganic semiconductors, such as silicon. As well known to those of ordinary skill in the art, acenes are polycyclic aromatic hydrocarbons consisting of fused benzene rings in a rectilinear arrangement. For instance, the use of aromatic organic molecules like pentacene instead of silicon would eliminate the costs of silicon processing in the fabrication of thin film field effect transistor (FET) devices. The use of semiconductive films made of aromatic organic molecules could provide other advantages, such as a reduced number of ste...

AI Technical Summary

Benefits of technology

[0005] To address one or more of the above-discussed deficiencies, one embodiment is a method. The method comprises reducing an acene

Problems solved by technology

Unfortunately, certain conventional synthetic routes for some aromatic organic molecules are undesirable.

This, in turn, deters the use of low-cost solution deposition processes to deposit thin semiconductive films of such molecule in the formation of electronic devices.
