Product Details

FFDA CAS 127926-65-2 for Fluorinated Polyimide Synthesis

9,9-Bis(3-fluoro-4-aminophenyl)fluorene, commonly known as FFDA, is a fluorinated fluorene-based diamine monomer used as a structural building block in high-performance polyimide and specialty polymer synthesis. Its rigid fluorene core, aromatic diamine structure and fluoro-substituted aminophenyl groups make FFDA relevant to polyimide systems where thermal resistance, rigidity, optical performance and dielectric behavior need to be balanced.

FFDA belongs to the broader category of polyimide diamine monomers and is also part of Aure Chemical’s polyimide diamine monomers supply portfolio. It is often considered in fluorinated, optical, low-dielectric and high-temperature polyimide material development, depending on the paired dianhydride, formulation and processing conditions.

Key Features in Polyimide Design

Fluorinated aromatic diamine structure, relevant to fluorinated polyimide diamine applications.
Rigid fluorene core may support thermal resistance, chain rigidity and dimensional stability depending on the paired dianhydride and polymer architecture.
Fluoro-substituted aromatic structure may be considered when dielectric behavior, optical performance and moisture-related properties are part of the target PI design.
FFDA can be evaluated in optical and transparent polyimide applications where reduced coloration and material clarity are design considerations.
Final material properties depend on monomer purity, dianhydride selection, solvent system, imidization conditions and polymer processing method.

Pairing FFDA with Dianhydride Monomers

In polyimide synthesis, FFDA may be evaluated with selected polyimide dianhydride monomers to design fluorinated, rigid and high-performance PI systems. Fluorinated dianhydrides such as 6FDA CAS 1107-00-2 may be considered when optical, dielectric or moisture-related properties are important.

Rigid aromatic dianhydrides such as BPDA CAS 2420-87-3 or BTDA CAS 2421-28-5 may support thermal resistance and dimensional stability, while ether-containing dianhydrides such as ODPA CAS 1823-59-2 may help improve processability and film-forming behavior.

Application Context of FFDA in Polyimide Systems

FFDA is typically used as a structural diamine monomer rather than a finished application material. It is commonly discussed in fluorinated, optical, dielectric and high-temperature polyimide material development, where fluorene rigidity and fluoro-substituted aromatic structures can influence polymer performance.

Fluorinated polyimide diamine applications – monomer selection for fluorinated PI systems.
Optical and transparent polyimide applications – optical clarity and reduced coloration in PI design.
Electronics and semiconductor polyimide applications – low-dielectric, insulation and electronic material requirements.
High-temperature polyimide applications – thermal resistance and high-performance polymer environments.
Specialty functional polyimide development – fluorinated and rigid diamine selection for advanced polymer research.

COA, SDS and Technical Documentation
