Poly(amide)s obtained from 4-(4-((4-(4-aminophenoxy)phenyl)diphenylsilyl)phenoxy)benzenamine and dicarboxylic acids containing diphenylsilarylene units. Synthesis and characterization

Flexible oligomeric silicon‐containing poly(ether‐azomethine)s obtained from epoxide derivatives. Synthesis and characterization

“…This signal was observed in phenyl‐silylated series, while a signal at −8 ppm was observed in methyl‐silylated series, and it is attributed to the PhSi(Me 2 )Ph moiety. This difference between the chemical shifts is related to the particular inductive effects produced by the methyl and phenyl groups on the heteroatom, which we have already reported and explained for several substituents …”

Silarylene-containing oligo(ether-amide)s based on bis(4-(4-amino phenoxy)phenyl)dimethylsilane. Effect of the dicarboxylic acid structure on some properties

“…Synthesis and spectroscopic characterization of monomers Di(ether-amine) 5 was synthesized according to a procedure described previously [23][24][25]29 (Scheme 1). The diphenolate was obtained from the silicon-containing compound 1, which reacts with two equivalents of 1-uoro-4-nitrobenzene by a nucleophilic aromatic substitution reaction.…”

“…These aromatic diamines have been used in the preparation of a series of oligo(ether-amide)s, which properties were related to the specic structure of the monomers. [23][24][25] In this work, we report the synthesis and characterization of three new difunctional compounds; a diamine and two dicarboxylic acids, all of them containing a diphenylsilane moiety and two oxyphenyl units in their structure. The others two substituted groups bonded to silicon atoms are methyl or phenyl for the diacid monomers and dimethyl for the diamine.…”

Synthesis and thermal, optical and morphological characterization of oligomeric polyamides based on thiophene and alkyl/phenyl‐silane moieties. Study of the electrospun deposition process

“…These polymers contain silicon and/or germanium and several organic substituents into their main chain favoring the flexibility of the system, allowing chain folding. These characteristics make these polymers suitable for manipulation generating possible technological implementation …”
