Photodeprotectable N-Alkoxybenzyl Aromatic Polyamides
N-alkoxybenzyl aromatic polyamides were synthesized by polycondensation of N-alkoxybenzyl aromatic diamine with equimolar dicarboxylic acid chloride in the presence of 2.2 equiv. of pyridine at room temperature for 2 days. The obtained polyamides were mainly cyclic polymers, as determined by means of matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry, and s...
متن کاملNovel Anodic Polyelectrochromic Aromatic Polyamides Containing Pendent Dimethyltriphenylamine Moieties
Two series of novel aromatic polyamides containing pendent dimethyltriphenylamine moieties were prepared based on N,N-bis(4-aminophenyl)-N′,N′-di(4-methylphenyl)-1,4-phenylenediamine (4) and N,Nbis(4-carboxyphenyl)-N′,N′-di(4-methylphenyl)-1,4-phenylenediamine (4′). These compounds with similar structures were successfully synthesized by amination reactions of 4-amino-4′,4′′-dimethyltriphenylam...
متن کاملThermal behaviour and fibre studies of certain new aromatic - aliphatic polyamides
Thirteen polyamides were synthesized by polycondensation using phosphorylation, low temperature solution and interfacial solution methods from 2, 2’-Dichloro-4, 4’-diaminoazobenzene condensed with different aliphatic diacids. These were characterised by inherent viscosity, solubility and spectral studies like UV-visible and IR. Moisture regain and dyeing properties have also been studied. TGA a...
متن کاملSynthesis and biological evaluation of new nanosized aromatic polyamides containing amido- and sulfonamidopyrimidines pendant structures
BACKGROUND Antibiotics are biocides or products that inhibit the growth of microorganisms in the living cells and there are extensive works directed to develop efficient antimicrobial agents. The sulfonamide-containing polymers have great potential to resist gram-positive or gram-negative bacterial and fungal attacks. As a therapeutic agent, the sulfonamides have been reported as antitumor and ...
