2,9-Bis[3-[[3-(dimethylamino)propyl]amino]propyl]anthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-1,3,8,10(2H,9H)-tetraone (TCI product code P3289, CAS 1020180-01-1) is a perylene diimide (PDI) derivative. The anthradiisoquinoline-tetraone framework in its name is the systematic name for the perylene diimide core. Each of the two imide nitrogens carries a side chain containing a secondary amine and a tertiary dimethylamino group. TCI lists this compound under organic solar cell (OPV) materials. In that field, amine-functionalized PDI derivatives like this one are commonly studied as cathode interlayers, the thin layers placed between the photoactive layer and the metal electrode.

Researchers choose this material because of how its core and side chains work together. The perylene diimide core is a large aromatic system known as a good electron acceptor. It is thermally and photochemically stable and absorbs visible light strongly. The amine side chains add two practical benefits. First, they make the compound soluble in polar solvents such as alcohols, so a thin film can be deposited on top of the active layer without dissolving the layer underneath. Second, the amine groups can form interfacial dipoles that help lower the work function of metal electrodes, which makes electron extraction in the device more efficient.

In Indonesian laboratories, this compound is relevant to renewable energy research, including next-generation solar cells. University materials science and physics departments, research institutes, and teams working on organic electronics can use it to build and optimize device architectures. Common work includes testing interfacial layers, comparing cathode modification strategies, and studying how interlayer chemistry affects device performance. It is a specialized research reagent, intended for experimental device fabrication and characterization rather than routine analytical work.

Keep this compound in its original, tightly sealed manufacturer container. Store it in a cool, dry place away from direct light, because organic electronic materials can degrade with prolonged exposure to light, moisture, and air. Follow any specific storage temperature or inert-atmosphere requirements on the TCI label and Safety Data Sheet. Work in a well-ventilated area or fume hood, and wear suitable gloves, safety glasses, and a lab coat. Avoid inhaling dust or getting the material on skin or in the eyes. When preparing alcohol-based solutions, use clean, dry glassware and close containers promptly after use to limit contamination. Dispose of waste according to local regulations and your institution's chemical safety procedures.
