Quality Control

Our Poly[[9-(1-octylnonyl)-9H-carbazole-2,7-diyl]-2,5-thiophenediyl[2,5-bis(2-ethylhexyl)-2,3,5,6-tetrahydro-3,6-dioxopyrrolo[3,4-c]pyrrole-1,4-diyl]-2,5-thiophenediyl] is synthesized and purified under strict inert atmosphere conditions to prevent oxidation and ensure batch-to-batch consistency. Each lot undergoes comprehensive analytical characterization to confirm molecular weight, purity, and optoelectronic properties. Certificates of Analysis (COA) detailing key specifications such as number-average molecular weight (Mn), polydispersity index (PDI), and residual metal content are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at a controlled room temperature (15-25°C) in a dry, cool place. Due to its sensitivity to light and oxygen, prolonged exposure to air should be avoided. For long-term storage, consider refrigeration (2-8°C) under inert gas.
