Synthesis of Polynitroxides Based on Nucleophilic Aromatic Substitution
摘要:
The scope and limitations of the synthesis of polynitroxides by nucleophilic substitution of electron-deficient fluorinated aromatic compounds are described. The method provides a facile route to the formation of polynitroxides exhibiting strong electron exchange between nitroxide groups.
A perfluorinated gradedindexpolymeropticalfiber (PFGI-POF) has been developed and manufactured for data communication to provide a high bandwidth with easy termination and cabling. In the PFGI-...
