摘要：
The present invention provides new polyimide materials suitable for use in optically transparent fiber composites, ribbon composites, and optical communications applications. The polyimide compounds include monomeric repeat units comprising a fluorinated moiety and a fluorene cardo structure. The polyimides exhibit good optical transparency and have a low absolute thermo-optic coefficient (|dn/dT|).
