1. Product Overview & Specifications

2,2′,7,7′-Tetrabromo-9,9′-Spirobifluorene (TBSF) is a brominated spirobifluorene derivative widely used in optoelectronic materials. Key parameters include:

2. Applications of TBSF

• OLED Materials: Acts as an electron-transport layer/hole-blocking layer to enhance device efficiency.
• Photoinitiators: Used in UV-curable resins for 3D printing and coatings.
• Flame Retardants: Bromine content improves fire resistance in polymers.
• Pharmaceutical Intermediates: Building block for bioactive molecule synthesis.

3. Usage Guidelines

• Safety: Use PPE (gloves, goggles) to avoid skin/eye contact. Handle under fume hood.
• Storage: Keep in airtight containers at 2-8°C, protected from light.
• Solubility: Soluble in THF, chloroform, and DCM; insoluble in water.
• Processing: Optimize concentration (0.5-2 wt%) in OLED layers for balanced charge transport.

4. Case Studies

Case 1: TBSF in Flexible OLED Displays

A leading display manufacturer integrated TBSF into their red phosphorescent OLED stack, achieving:

• 20% increase in external quantum efficiency (EQE)
• 15% longer operational lifetime vs. non-brominated analogs

Case 2: High-Speed 3D Printing Resins

A 3D printing company used TBSF-based photoinitiators to:

• Reduce curing time by 40% under 365 nm UV
• Enable micron-scale resolution in dental aligner production

5. Client Success Stories
