SPIRO-OMETAD POWDER 99.8% TRIPLE PURIFIED CAS 207739-72-8 HTL

RESEARCH GRADE MATERIAL

Product Overview
Spiro-OMeTAD Powder (2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene, CAS 207739-72-8) is a high-purity hole transport material with 99.8% triple purified CAS 207739-72-8 quality, supplied as a light yellow or white powder with a molecular weight of 1225.43 g/mol. This material serves as the industry-standard perovskite solar cell hole transport layer (HTL) for high-efficiency n-i-p architecture devices. The triple purification process ensures extremely low impurity content, uniform powder morphology, and stable dissolution behavior in standard HTL solvents including chlorobenzene and o-dichlorobenzene. The excellent batch-to-batch stability—characterized by minimal color variation, no agglomeration, and uniform film formation—directly contributes to enhanced device power conversion efficiency and experimental reproducibility. Available in 1 g, 5 g, and 10 g specifications, this glovebox storage moisture-sensitive light-protected material requires strict handling protocols to maintain its electronic performance characteristics.

Key Features & Advantages
  • Triple Purification Process with ≥99.8% Purity: The three-stage purification process delivers extremely low impurity content, eliminating charge trapping sites and parasitic recombination pathways that compromise hole extraction efficiency in completed perovskite devices.
  • Uniform Powder Morphology with Stable Dissolution Behavior: The homogeneous powder morphology ensures consistent and efficient dissolution in chlorobenzene, o-dichlorobenzene, and other standard HTL solvents, enabling reproducible solution preparation for spin-coating deposition.
  • Excellent Batch-to-Batch Stability for Experimental Reproducibility: Rigorous quality control ensures minimal color variation, no agglomeration or clumping, and uniform film formation across production batches, directly supporting reliable device efficiency data across extended research programs.
  • Industry-Standard HTL Material for High-Efficiency PSCs: Spiro-OMeTAD remains the benchmark hole transport material for n-i-p architecture perovskite solar cells, with its well-characterized electronic properties enabling straightforward integration into established device fabrication protocols.

APPLICATION SCOPE: Core hole transport layer material for high-efficiency perovskite solar cells in n-i-p device architecture. Hole transport material for organic photovoltaic devices. Charge transport layer for photodetector and light-emitting diode optoelectronic thin film research. Solution-processable HTL for flexible and tandem perovskite devices. Compatible with spin-coating deposition from chlorobenzene and o-dichlorobenzene solutions with appropriate dopants (Li-TFSI, tBP) for enhanced conductivity.
PACKAGING: Available in 1 g, 5 g, and 10 g specifications. Each package is sealed under inert atmosphere within light-protective, moisture-barrier packaging. The moisture-sensitive nature of Spiro-OMeTAD necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For optimal performance, store in a glovebox or vacuum desiccator.
IMPORTANT NOTICE: Spiro-OMeTAD is moisture-sensitive and degrades upon exposure to ambient humidity. Conduct all weighing, dispensing, and solution preparation within a glovebox or low-humidity environment (H₂O < 1 ppm). The material is susceptible to degradation upon prolonged exposure to moisture, which compromises its hole transport properties and device performance. After opening, use the contents promptly and reseal the container immediately. Avoid direct skin contact and inhalation of powder—wear protective gloves and a dust mask during handling. Store in a sealed container in a cool, dry, light-protected environment; avoid high temperature, humidity, and direct UV exposure. For detailed safety and handling information, consult the Safety Data Sheet prior to use.

This material degrades upon exposure to ambient humidity, requiring glovebox or low-humidity environment handling. Prolonged UV exposure and high temperatures also compromise its hole transport properties.

  • Moisture Sensitivity: Conduct all weighing, dispensing, and solution preparation within a glovebox or low-humidity environment with H₂O below 1 ppm.
  • Light and Temperature Protection: Store in a sealed, cool, dry, light-protected container, avoiding high temperature, humidity, and direct UV exposure.
  • Post-Opening Protocol: After opening, use the contents promptly and reseal the container immediately to prevent moisture ingress.

This procedure describes safe handling and solution preparation of moisture-sensitive Spiro-OMeTAD powder. All steps must be performed in a glovebox with controlled atmosphere to preserve material integrity.

Required Equipment: Glovebox with inert atmosphere (H₂O < 1 ppm), Light-protective, moisture-barrier container, Analytical balance, Protective gloves and dust mask

  1. Transfer material to glovebox
    Transfer the sealed Spiro-OMeTAD container into a glovebox with H₂O below 1 ppm before opening.
  2. Weigh required amount
    Weigh the desired mass of Spiro-OMeTAD powder on an analytical balance inside the glovebox.
  3. Prepare HTL solution
    Dissolve the weighed powder in anhydrous chlorobenzene or o-dichlorobenzene at the desired concentration, stirring until fully dissolved.
  4. Add dopants if required
    Add appropriate dopants such as Li-TFSI and tBP to the solution for enhanced conductivity, mixing thoroughly.
  5. Deposit HTL film
    Spin-coat the prepared solution onto the perovskite substrate inside the glovebox to form the hole transport layer.

Why is triple purification to ≥99.8% critical for Spiro-OMeTAD performance in perovskite solar cells?

Triple purification to ≥99.8% purity eliminates charge trapping sites and parasitic recombination pathways that compromise hole extraction efficiency in completed perovskite devices. The three-stage process ensures extremely low impurity content, uniform powder morphology, and stable dissolution behavior, directly contributing to enhanced power conversion efficiency and experimental reproducibility.

Which solvents and dopants are compatible with Spiro-OMeTAD for spin-coating deposition?

Spiro-OMeTAD is efficiently soluble in chlorobenzene and o-dichlorobenzene, as well as common HTL solvents. For enhanced conductivity in device fabrication, it is compatible with dopants such as Li-TFSI and tBP, which are added to the solution prior to spin-coating deposition.

What are the critical storage and handling requirements for Spiro-OMeTAD powder to prevent degradation?

Spiro-OMeTAD is moisture-sensitive and degrades upon exposure to ambient humidity. All weighing, dispensing, and solution preparation must be conducted in a glovebox or low-humidity environment (H₂O < 1 ppm). The material must be stored sealed, cool, dry, and light-protected, avoiding high temperature, humidity, and UV exposure. After opening, use promptly and reseal immediately.

This Spiro-OMeTAD powder (CAS 207739-72-8) is a triple-purified (≥99.8%) hole transport material for n-i-p perovskite solar cells, supplied in 1 g, 5 g, and 10 g quantities. Its uniform powder morphology and stable dissolution in chlorobenzene or o-dichlorobenzene support reproducible spin-coating, but strict glovebox handling (H₂O < 1 ppm) and light-protected storage are mandatory to prevent moisture-induced degradation of hole transport properties.

  • Triple Purified ≥99.8% Purity: The three-stage purification eliminates charge-trapping impurities and parasitic recombination pathways, directly enhancing hole extraction efficiency and device power conversion in perovskite solar cells.
  • Excellent Batch-to-Batch Stability: Minimal color variation, no agglomeration, and uniform film formation across batches ensure reproducible device performance and reliable experimental data over extended research programs.

Trade-offs

  • Strict Moisture Sensitivity: Spiro-OMeTAD degrades upon exposure to ambient humidity; all weighing, dispensing, and solution preparation must be conducted in a glovebox or low-humidity environment (H₂O < 1 ppm) to preserve hole transport properties.
  • Light-Protected Storage Required: The material is susceptible to degradation from UV exposure and high temperature, necessitating sealed, cool, dry, light-protected storage and immediate transfer to a desiccated environment after opening.
