Pentacene-N-sulfinyl-tert-butylcarbamate
Pentacene-N-sulfinyl-tert-butylcarbamate (CAS: 794586-44-0, C27H23NO3S) is a versatile organic building block and a photopatternable pentacene precursor. It exhibits high solubility in apolar organic solvents like THF and halogenated solvents. Upon heating under nitrogen, it converts to pentacene, enabling its use in fabricating organic electronics. This precursor is crucial for developing materials for organic field-effect transistors (OFETs) and printed electronics.

Pentacene Precursor for Organic Electronics
This compound serves as a precursor to pentacene, a key material in organic electronics. Solution-processed thin films of this precursor can be converted to pentacene, facilitating the fabrication of organic thin-film transistors (OTFTs) with good charge carrier mobilities.
Photopatternable Material
The precursor allows for photopatterning of pentacene films. Exposure to UV light in the presence of a photoacid generator, followed by mild heating, enables selective conversion to pentacene, enabling precise pattern formation for electronic device fabrication.
Organic Field-Effect Transistor (OFET) Materials
It is instrumental in the development of p-type organic semiconductors for OFET applications. Devices fabricated using this precursor have demonstrated promising performance characteristics, including significant mobilities and on/off ratios.
Chemical Synthesis Building Block
As a complex organic molecule, it functions as a valuable building block in organic synthesis and materials science, enabling the creation of novel functional materials with tailored electronic properties.

| Application | Photopatternable pentacene precursor highly solube in apolar organic solvents (halogenated solvents, THF). Converted to pentacene in thin (e.g. spin-cast) films by heating under N2 atmosphere for one hour at 150 °C. Spin-coated thin films of the pentacene precursor can be patterned by exposure to UV light in the presence of a photoacid generator (e.g. 531014), followed by a brief heating (5 min. at 130 °C and washing away of an un-converted precursor. Organic thin film transistors fabricated by solution processing of this precursor showed mobilities of 0.13 cm2V-1s-1 and on/off ratio 2 x 105.1 |
