Phenanthro[1,2-b:8,7-b']dithiophene TCI P2383

Phenanthro[1,2-b:8,7-b']dithiophene from TCI is a polycyclic aromatic compound built on a phenanthrene core with a thiophene ring fused at each end. It belongs to the small-molecule organic semiconductors that researchers study as active materials for organic field-effect transistors (OFETs). In the laboratory it can be used directly as the semiconductor layer when fabricating test devices. It can also serve as a core structure for making alkylated or otherwise functionalized derivatives, so it is useful both for building devices and for synthesis.

The planar, extensively conjugated framework is what makes this material attractive. That geometry supports π–π stacking between molecules in the solid state, and this kind of stacking is important for charge transport. The literature reports that fusing thiophene rings onto a "bent" phenanthrene framework (a phenacene-type structure) is one way to obtain p-type semiconductors that are more stable in air than linear acenes such as pentacene. High purity matters a great deal in this field because even small amounts of impurity can act as charge traps and reduce device performance. Researchers therefore need consistent, well-characterized starting material.

In Indonesia, this material is relevant to research groups in materials physics, organic electronics, and chemistry at universities and research institutes. Typical work includes making and testing thin-film transistors, comparing how molecular structure affects charge transport, and synthesizing new semiconductor derivatives from this core. It also fits student thesis and dissertation projects on organic semiconductors, and collaborative projects that need a reference compound from a recognized brand for repeatable experiments and fair comparison with published results.

• OFET active-layer fabrication: the compound can be deposited directly as the semiconductor layer in test transistors, so researchers can measure charge-transport behaviour of a planar, conjugated small molecule.
• Synthesis of functionalized derivatives: the phenanthrodithiophene core works as a starting scaffold for alkylated or otherwise functionalized semiconductors with adjusted solubility, packing, or electronic properties.
• Structure–property relationship studies: its bent, phenacene-type framework makes a useful comparison point against linear acenes such as pentacene when studying how molecular shape affects stability and charge transport.
• Air-stability investigations of p-type semiconductors: the literature links thiophene-fused phenacene structures with better air stability, so the material suits experiments on device degradation under ambient conditions.
• Teaching and thesis research in organic electronics: as a well-defined small-molecule semiconductor, it supports student projects that involve device fabrication, thin-film characterization, and comparison with published data.

Keep this material in its original, tightly sealed container in a cool, dry, dark place, away from strong oxidizing agents and sources of heat. Because impurities can act as charge traps and lower device performance, avoid contamination. Use clean, dry spatulas and glassware, keep exposure to air and moisture to a minimum, and consider handling and storing the material under inert gas or in a glovebox when making devices. Wear the usual laboratory protective equipment, including gloves, safety glasses, and a lab coat, and work in a well-ventilated area or fume hood. Always check the supplier's Safety Data Sheet and label for the specific storage conditions and hazard information before use.
