It belongs to the family of perovskite solar cell (PSC) materials and functions as an n-type molecular dopant. Its laboratory role is to donate electrons or hydride to the surrounding semiconductor material, increasing the number of free charge carriers within the layer and measurably lowering the electrical resistance of the device during characterisation work.\u003c\/p\u003e\n\u003cp\u003eThe property that makes this compound a preferred choice is the strength of its donor character. The dimethylamino group is among the strongest electron-donating groups available on an aromatic system, while the four additional methyl groups on the benzimidazole framework further raise the electron density of the core and provide steric protection that helps suppress side reactions. After releasing hydride or an electron, the molecule forms a benzimidazolium cation that is stabilised by aromatisation, and this stabilisation is the principal driving force behind the doping process. As a neutral, solution-processable dopant, the compound integrates readily into standard film deposition routines.\u003c\/p\u003e\n\u003cp\u003eIn Indonesian laboratories, this material is typically used by university research groups, national research institutes and materials laboratories working on next-generation photovoltaics. It is normally handled in small quantities inside a glove box or controlled atmosphere, dissolved in an appropriate organic solvent and applied to electron transport layers or charge transport films. Researchers use it during device fabrication trials where carrier concentration, sheet resistance and layer conductivity are measured before and after doping.\u003c\/p\u003e\n\u003ch3\u003eLaboratory Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eN-type doping of electron transport layers in perovskite solar cells, where the compound raises free carrier density and reduces series resistance across the fabricated stack during device testing.\u003c\/li\u003e\n\u003cli\u003eConductivity enhancement studies of organic semiconductor films, because the strong dimethylamino donor allows researchers to correlate dopant loading with measured sheet resistance in a controlled way.\u003c\/li\u003e\n\u003cli\u003eCharge transport layer optimisation in photovoltaic device fabrication, since the neutral solution-processable form permits simple blending into existing coating formulations without additional reagent handling steps.\u003c\/li\u003e\n\u003cli\u003eFundamental doping mechanism research, as the aromatisation-stabilised benzimidazolium cation formed after hydride release provides a clear, well-defined chemical driving force for mechanistic investigation.\u003c\/li\u003e\n\u003cli\u003eComparative dopant screening experiments, where the four extra methyl groups and their steric protection help suppress side reactions and give cleaner baselines against alternative n-type dopant candidates.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: TCI (Tokyo Chemical Industry)\u003c\/li\u003e\n\u003cli\u003eCAS Number: 2376423-07-1\u003c\/li\u003e\n\u003cli\u003eCategory: Materials Science \u0026gt; Electronic Materials \u0026gt; Perovskite Solar Cell (PSC) Materials\u003c\/li\u003e\n\u003cli\u003eChemical class: dihydrobenzimidazole derivative bearing a dimethylaminophenyl substituent, used as an n-type molecular dopant\u003c\/li\u003e\n\u003cli\u003ePack sizes: available in standard TCI research-scale packaging; please confirm the currently available pack size when ordering\u003c\/li\u003e\n\u003cli\u003eStorage note: keep in a cool, dry place away from light and air, in accordance with the manufacturer's storage instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHandling and Storage\u003c\/h3\u003e\n\u003cp\u003eStore the container in a cool, dry and well-ventilated area, protected from light, moisture and prolonged contact with air, following the storage conditions stated by the manufacturer on the product label and safety data sheet. Keep the material in its original tightly closed container; for laboratory aliquots, use clean amber glass vials with inert-compatible closures and, where practical, store and weigh under an inert atmosphere. As a strong electron donor, the compound should be kept away from oxidising agents. Handle in a fume hood or glove box using gloves, safety glasses and a laboratory coat, avoid generating dust, and consult the manufacturer's safety data sheet before use and disposal.\u003c\/p\u003e","brand":"TCI","offers":[{"title":"1g","offer_id":48086795518170,"sku":"TCI2510D619427245","price":4743900.0,"currency_code":"IDR","in_stock":true},{"title":"5g","offer_id":48086795550938,"sku":"TCI2510D619427246","price":16535400.0,"currency_code":"IDR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/7156\/8602\/files\/TCI2510D6194.jpg?v=1768818571","url":"https:\/\/amiscientific.com\/en\/products\/tci2510d619427245","provider":"AMI Scientific","version":"1.0","type":"link"}
