Description
TIPS-Pentacene is tri-isopropylsilyly-ethynyl (TIPS) substituted pentacene at 6- and 13-positions of the conjugated core. The substituted TIPS functional groups extend the conjugation further to the branches to provide further stability, enhance solubility for solution processing?for low-cost and large-area fabrication of organic thin-film transistors (OTFTs).
Odor Dark blue solid
Solvent Anisole, butylbenzene, chlorobenzene, chloroform, dichlorobenzene, tetrahydrofuran, toluene, xylene
