ABSTRACT:
A previously unknown phase of .alpha.-hexathienyl, designated .alpha.-6T/HT, exhibits diffraction peaks at 2.theta.=4.31.degree., 8.64.degree., 12.96.degree., 17.32.degree., 26.15.degree. and 29.08.degree. in a CuK.sub..alpha. powder X-ray diffraction pattern, and is expected to have properties (e.g., high hole mobility) that make the phase desirable for use in, e.g., thin film transistors. Substitution of thin films of .alpha.-6T/HT for prior art organic thin films in thin film transistors and other devices is contemplated.
