Descrição geral

Pentacene belongs to the class of fused polycyclic hydrocarbons that are a part of the acene family with five rings. It is majorly utilized in electronic applications due to its high hole mobility of 1200 cm2V−1s−1 and fluorescent absorption peak at the wavelength of 578 nm.
Pentacene is a popular organic semi conductor. Upon deposition on any insulating substrate, the molecules organize to form polycrystalline films. The pentacene films show good transport properties. The hydrogen atoms which surround the carbon backbone are less electronegative than the carbon backbone itself and lend some electron density to the delocalized pi-electron cloud. It can also form large crystals.

Aplicação

Pentacene can be functionalized by treating it with poly(4-vinyl phenol) (PVP), which can be used to reduce the surface energy of organic thin film transistors (OTFTs) and increase the hole mobility by 109%. It is mainly used in the fabrication of field effect transistors, which can be doped with iodine to increase the threshold voltage up to 140 V.

Dr. Chan and researchers highlight flexible transistors are the building blocks of next-generation soft electronics. Among all the reported material systems that can be fabricated by researchers, such as circuits, biosensors, stretchable displays, and others,1–5 small molecular weight organic semiconductors are among the most promising candidates for flexible transistor applications. For these small molecular weight organic semiconductors, the semiconductor forming the conductive channel dominates the device performance.

Polymer Semiconductors for Intrinsically Stretchable Organic Transistors

There is widespread demand for thin, lightweight, and flexible electronic devices such as displays, sensors, actuators, and radio-frequency identification tags (RFIDs). Flexibility is necessary for scalability, portability, and mechanical robustness.
