N,N'-Di-n-octyl-3,4,9,10-perylenetetracarboxylic Diimide TCI D4175

Description

TCI D4175 is N,N'-Di-n-octyl-3,4,9,10-perylenetetracarboxylic Diimide, a compound belonging to the perylene diimide (PDI) family and more commonly known in the electronic materials research community by the abbreviation PTCDI-C8. This material functions as an n-type organic semiconductor, meaning it acts as the electron-transporting component that pairs with a p-type donor material within organic solar cell architectures. In the laboratory, the compound is used as an active layer in organic photovoltaic devices, as the channel material in organic field-effect transistors, and simultaneously as a model dye and fluorophore for studies of excited-state photophysics and intermolecular charge transfer.

The characteristics that make this compound a frequent choice are found in its perylene diimide core, which is π-electron rich, rigid, and planar. Because of this molecular geometry, the molecules tend to organize themselves into stacked arrangements through π–π stacking, forming ordered electron conduction pathways within thin films. The n-octyl groups attached to both imide nitrogen atoms serve as side chains that improve solubility in common organic solvents while also regulating intermolecular spacing during film formation. The perylene diimide core is likewise recognized for its good thermal and photochemical stability, which supports reproducible device fabrication and measurement.

In Indonesian laboratories, this material is typically encountered in university and institutional research groups working on organic electronics and renewable energy materials. It is handled in solution-processing workflows where thin films are deposited from organic solvents, and in device studies where electron-transport behavior must be characterized. Its role as a well-documented reference n-type semiconductor also makes it suitable for teaching laboratories and for benchmarking newly synthesized acceptor materials against an established standard.

Laboratory Applications

• Organic photovoltaic (OPV) active layers — the compound serves as the electron-accepting partner to p-type donor materials, providing the n-type half of the donor–acceptor blend required for charge separation in organic solar cell architectures.
• Organic field-effect transistor (OFET) channels — its planar, π-stacked molecular packing forms ordered electron conduction pathways in thin films, making it suitable as the semiconducting channel in n-channel transistor devices.
• Excited-state photophysics studies — as a model fluorophore with a well-characterized perylene diimide chromophore, it is widely used to investigate excited-state behavior under spectroscopic examination in research laboratories.
• Intermolecular charge transfer investigations — the electron-rich perylene diimide core makes this compound a reliable model system for studying how charge is transferred between molecules in condensed films and blends.
• Solution-processed thin film fabrication — the n-octyl side chains improve solubility in common organic solvents and regulate intermolecular spacing, allowing controlled film deposition and reproducible layer formation during device preparation.

Handling and Storage

Store the material in its original tightly closed container in a cool, dry, and well-ventilated area, protected from direct light and away from sources of ignition and incompatible chemicals. Because this compound is a dye and fluorophore, light protection helps preserve its optical and electronic behavior over time; amber glass vials or the supplier's original light-shielding packaging are appropriate. Handle the powder inside a fume hood to minimize dust generation and inhalation, and use standard personal protective equipment including a laboratory coat, chemical-resistant gloves, and safety goggles. Avoid contact with skin, eyes, and clothing, and wash hands thoroughly after handling. When preparing solutions in organic solvents, observe the precautions applicable to the solvent used, including adequate ventilation and control of ignition sources. Keep containers closed when not in use to prevent moisture uptake and contamination, and dispose of waste material and contaminated consumables according to institutional and local laboratory waste regulations. Always consult the manufacturer's Safety Data Sheet before use.
