General description

6,13-Bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) is a conductive polymer that can form organic thin films for a variety of semiconductor applications due to its high charge carrier mobility and stability.

Application

TIPS Pentacene is a high-performance soluble organic semiconductor for printed and flexible electronics applications. Material Matters 4.3 - Organic and Molecular Electronics Examples include the fabrication of organic field effect transistors (OFETs) with the highest reported switching speeds and field-effect mobilities in its class.
TIPS-pentacene forms a hybrid with (6,6)-phenylC61-butyric acid methyl ester (PCBM) which can be used as an organic layer that can be coated onto a silicon (Si) substrate for the fabrication of a highly efficient terahertz (THz) modulator. It can be used as a piezoresisitive sensor that produces multiple strain sensors (single sensors and sensor arrays). Organic thin-film transistors can be developed by using silver electrodes as dielectric materials and TIPS-pentacene as a semiconducting layer, which can be deposited via inkjet printing.

The conductivity of organic semiconductors can be increased, and the barriers to charge-carrier injection from other materials can be reduced, by the use of highly reducing or oxidizing species to n- or p-dope, respectively, the semiconductor.

Silylethyne-Substituted Pentacenes

Dr. Chan and researchers highlight flexible transistors are the building blocks of next-generation soft electronics. Among all the reported material systems that can be fabricated by researchers, such as circuits, biosensors, stretchable displays, and others,1–5 small molecular weight organic semiconductors are among the most promising candidates for flexible transistor applications. For these small molecular weight organic semiconductors, the semiconductor forming the conductive channel dominates the device performance.
