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.


Silyethyne-Substituted Pentacenes

TIPS-pentacene forms a hybrid with (6,6)-phenylC61-butyric acid methyl ester (PCBM) which can be used as an organic layer than 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.
