Pentacene (purified by sublimation) TCI P0030

Pentacene is a polycyclic aromatic hydrocarbon made of five benzene rings fused in a straight line, and it belongs to the acene family. It is one of the most widely studied organic semiconductors and is often used as a reference material in organic electronics research. This TCI product has been purified by sublimation. That step matters for semiconductor materials, because even very small amounts of impurity can sharply reduce device performance. In the laboratory, pentacene is used as the active layer in transistors, as a material for photophysics studies, and as a building block for acene derivatives.

Researchers choose pentacene because its large conjugated pi-electron system gives it a fairly narrow energy gap and good charge transport in the solid state. In well-ordered thin films, pentacene molecules stack closely, so holes can move between them efficiently. This is why pentacene is known as the benchmark p-type organic semiconductor. It is also well known in research on singlet fission, a process that could improve solar cell efficiency. Because the material is purified by sublimation, results are more consistent and easier to reproduce. This is especially important when electrical or optical measurements depend on how pure the material is.

In Indonesian laboratories, pentacene is mainly used by university research groups and research institutes working in materials science, applied physics, and organic chemistry. Typical work includes making and testing organic thin-film transistors, studying how molecules pack in vacuum-deposited films, and running spectroscopy experiments on excited-state behaviour. Synthetic chemists also use it as a starting point for new acene derivatives. Its long history in the literature makes it a dependable reference when a group is setting up new organic electronics methods.

• Organic thin-film transistors: pentacene is the standard p-type semiconductor for active channel layers, because its ordered molecular stacking lets holes move efficiently through the film.
• Reference material for organic electronics: as one of the most studied organic semiconductors, it gives a well-documented baseline for comparing new materials and checking fabrication processes.
• Photophysics and spectroscopy studies: its large conjugated pi-electron system and fairly narrow energy gap make it a good model compound for studying light absorption and excited-state behaviour.
• Singlet fission research: pentacene is one of the best-known materials for studying singlet fission, a process that could raise solar cell efficiency, so it is a key compound in this field.
• Synthesis of acene derivatives: as a non-heterocyclic building block, it is a useful starting structure for making modified acenes with adjusted electronic or solubility properties for further research.

• Grade: Purified by sublimation

Keep pentacene in a tightly closed original container, in a cool, dry and dark place. Like many acenes, pentacene is sensitive to environmental conditions, especially light and air, and long exposure can degrade the material and lower its semiconductor performance. Where possible, store and handle it under an inert atmosphere, for example in a glovebox or a sealed container flushed with nitrogen or argon. Amber glass or opaque containers help protect it from light. Follow standard laboratory safety practice: wear gloves, safety glasses and a lab coat, avoid breathing in dust, and work in a fume hood or ventilated area. Always check the supplier's Safety Data Sheet for full hazard and disposal information before use.
