Product Details

6FODA CAS 344-48-9 for Fluorinated Polyimide Synthesis

2,2'-Bis(trifluoromethyl)-4,4'-diaminodiphenyl ether, commonly known as 6FODA, is a fluorinated ether-containing diamine monomer used as a structural building block in high-performance polyimide synthesis. Its trifluoromethyl groups and flexible ether linkage make 6FODA relevant to polyimide systems where dielectric behavior, optical performance, solubility, flexibility and processability need to be balanced.

6FODA belongs to the broader category ofpolyimide diamine monomersand is also part of Aure Chemical’spolyimide diamine monomers supply portfolio. It is often considered in fluorinated polyimide material design, especially when a polymer system requires a combination of low dielectric behavior, reduced moisture uptake, optical clarity and improved processability.

Key Features in Polyimide Design

Fluorinated diamine structure, relevant to fluorinated polyimide diamine applications.
Trifluoromethyl groups may help reduce polarizability and support low-dielectric behavior depending on the paired dianhydride and polymer design.
Ether linkage may improve chain flexibility, solubility and processability in selected polyimide systems.
Reduced intermolecular interactions may support transparent and optical polyimide materials depending on the full polymer structure.
The final material properties depend on monomer purity, dianhydride selection, solvent system, midization conditions and processing method.

Pairing 6FODA with Dianhydride Monomers

In polyimide synthesis, 6FODA may be evaluated with selected polyimide dianhydride monomers to design fluorinated, flexible and processable PI systems. Fluorinated dianhydrides such as 6FDA CAS 1107-00-2 may be considered when transparent, low-dielectric or low-moisture-uptake polyimide systems are required.

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 further support processability and film-forming behavior.

Application Context of 6FODA in Polyimide Systems

6FODA is typically used as a structural monomer rather than a finished application material. It is commonly discussed in fluorinated, transparent, flexible and low-dielectric polyimide material development, where ether linkages and trifluoromethyl groups can influence free volume, dielectric behavior, optical properties and processability.

Fluorinated polyimide diamine applications – monomer selection for fluorinated PI systems.
Transparent and optical polyimide materials – optical clarity and reduced coloration in PI design.
Flexible and processable polyimide formulations – solubility, chain flexibility and film formation considerations.
Electronics and semiconductor polyimide applications – low-dielectric and insulation-related material requirements.
