TIPS-Pentacene
TIPS Pentacene, p-type organic semiconductor with a high purity of >99.9%
High hole mobility and excellent air stability
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).
TIPS pentacene has been developed as a p-type organic semiconductor, and demonstrates high hole mobility and excellent air stability with great solution processability. The substitution of two bulky side groups can not only significantly enhance the solubility of TIPS-pentacene in most of the common solvents but also prevent the middle acene from oxidation and degradation. The tri-isopropylsilyly-ethynyl side groups can also interrupt the edge-to-face interaction of the aromatic ring to avoid the herringbone packing motif in neat pentacene. The ethynyl groups keeps the bulky side tri-isopropylsilyly groups away from the aromatic ring to allow π-π stacking between adjacent TIPS pentacene molecules.
