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 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.
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.

We employ a combination of linear spectroscopy, electrochemistry, and transient absorption spectroscopy to characterize the interplay between electron transfer and singlet fission dynamics in polyacene-based dyes attached to nanostructured TiO2. For triisopropyl silylethynyl (TIPS)-pentacene, we find that the singlet fission...

Metal-Organic Complexes for Doping Organic Semiconductors and Surface Doping

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.
