Properties of Fluorinated Polyimides
This paper reports on two fluorinated polyimides synthesized using a fluorinated diamine, 2,2'-bis(trifluoromethyl) -4,4'-diaminobiphenyl (TFDB). One polyimide, synthesized with TFDB and 2,2'-bis(3,4dicarboxyphenyl)hexafluoropropane (6FDA), has a low dielectric constant, high optical transparency, and a low refractive index. The other, synthesized with TFDB and pyromellitic dianhydride (PMDA), ...
متن کاملPolyimides: promising energy-storage materials.
Based on this redox mechanism, we developed a series of polyamides with different structures and investigated their electrochemical activity as cathode materials for rechargeable lithium batteries. The results show that the polymer framework endows these samples with excellent cycling stability. Additionally, their capacity and rate capability are also satisfactory. The five polyimides were obt...

Principles of sequence-recognition in aromatic polyimides.
Pyrene-based molecular tweezers show sequence-specific binding to aromatic polyimides through sterically-controlled donor-acceptor pi-stacking and hydrogen bonding; (1)H NMR spectra of tweezer-complexes with polyimides having different sequence-restrictions show conclusively that the detection of long range sequence-information results from multiple tweezer-binding at adjacent imide residues.
