The synthesis and properties of new polyimides (PIs) derived from 4,4′-bis(p-aminophenoxy)triphenylamine (APT) and N,N-bis[4-(4′-aminophenoxy)phenyl]aminopyrene (APPA) for memory device application is reported. The starting monomers were prepared from 4-iodophenol and 4-fluoronitrobenzene via etherification (giving 4-(4′-nitrophenoxy)iodobenzene) followed by amination with aniline or aminopyrene and final reduction of terminal nitro-group. Polyimides were synthesized by polycondensation of each monomer with hexafluoroisopropylidene-2,2-bis(phthalic anhydride) in dimethylacetamide. All PIs had electron-rich arylamine moieties combining flexible phenyl-ether linkages which provide polymers electron-donating properties to reduce driving voltage in a memory device. The PIs exhibited high thermal properties such as 10% weight loss temperature >500° and glass transition temperatures >250°. The effects of structure on the thermal, optical, and electrochem. properties of the PIs are described in detail. This study involved multiple reactions and reactants, such as 1-Iodo-4-(4-nitrophenoxy)benzene (cas: 21969-05-1Electric Literature of C12H8INO3).
1-Iodo-4-(4-nitrophenoxy)benzene (cas: 21969-05-1) belongs to iodide derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent. Indole was synthesized in moderate yield via an o-naphthoquinone catalyzed tandem cross-coupling of substituted aniline and benzylamine under aerobic oxidation conditions.Electric Literature of C12H8INO3
