NPB
NPB is the trade name for N,N'-Bis(naphthalen-1-yl)-N,N'-bis(phenyl)benzidine, an organic semiconductor supplied by Jilin Optical And Electronic Materials Co., Ltd. The supplier offers the material as a fine powder with a stated purity range of 99.5 % to 99.9 % and provides the molecular formula C44H32N2. The product is packed in sealed moisture‑proof containers to protect it from oxygen and humidity, and bulk shipments are arranged on a flexible MOQ basis. No specific price is listed, and the supplier notes that chemical analysis can be supplied on request.
In the OLED and organic electronic industry, NPB is valued for its high hole‑mobility and thermal stability, typically tolerating temperatures up to 350 °C without degradation. Standard specifications for high‑purity NPB include a moisture content below 0.1 %, particle sizes under 50 µm, a density around 1.20 g/cm³ and an optical bandgap near 2.5 eV. These parameters are consistent with the values reported in the literature for this class of hole‑transport materials and are used by manufacturers to ensure consistent device performance. The sealed packaging also aligns with common practice for protecting sensitive organic semiconductors during transport and storage.
Device manufacturers, display panel makers and research laboratories source NPB for use as a hole‑transport layer in OLED stacks, as well as for experimental organic electronic devices. The supplier indicates that shipments can be arranged on FOB or CIF terms, and that payment methods such as L/C or T/T are accepted. Buyers are encouraged to confirm the required quantity, packaging size and any additional testing or certification needs before finalising the order.

Sourcing NPB from Jilin Optical And Electronic Materials Co., Ltd - China Import Guide
Importers should first verify the declared purity range of 99.5 % - 99.9 % by requesting the supplier’s analytical certificate and ensure that the moisture‑proof packaging meets the <0.1 % moisture requirement for sensitive OLED applications. It is also advisable to obtain a material safety data sheet and confirm that the product conforms to any relevant industry standards for organic semiconductors.
Logistics for NPB are quoted on FOB or CIF terms, so the buyer must arrange freight forwarding, insurance and customs clearance for the destination port. Because lead times are not disclosed, the importer should ask the supplier to provide an estimated production schedule, container loading plan and acceptable incoterms such as DAP or DDP. Payment is usually secured by L/C or T/T, and the buyer should align the payment schedule with the shipment milestones to manage cash flow risk.
Quality assurance should include a review of the supplier‑provided purity and moisture analysis, as well as an independent test of particle size and thermal stability if the end‑use demands tight tolerances. Buyers are encouraged to request a certificate of conformity and, where required, an independent laboratory report before the final payment is released. Proper documentation - including commercial invoice, packing list, certificate of origin and material safety data sheet - will facilitate smooth customs clearance and reduce the risk of shipment delays.
