Applications

1,4,8,11-tetramethyl-6,13-triethylsilylethynyl pentacene also known as TMTES-Pentacene. It is a soluble derivative of Pentacene [1], achieving mobilities of up to 4.34 cm2/Vs. TMTES-Pentacene is an ideal small-molecule semiconductor for both device fabrication and investigating the charge transport of solution-processed crystal semiconductor [4]. Mobilities of 3.5 cm2/Vs have been measured when spin coated using CYTOP© as the gate dielectric [2], and mobilities of up to 4.34  cm2/Vs have been achieved when used with high-permittivity polymer binders [3].
