Characterization of polypyrrole/azocalix[4]arene salts: Electrical properties and thermal stability

Polypyrrole (PPy) was doped with the azocalix[4]arene [(5,11,17,23-tetrakis[(p-carboxyphenyl)azo]25,26,27,28-tetrahydroxycalix[4]arene)] host species. PPy/azocalix[4]arene salts were characterized by FTIR, TGA, SEM, X-ray diffraction, and conductivity measurements. The properties of PPy were investi...

Beschreibung
Zusammenfassung:	Polypyrrole (PPy) was doped with the azocalix[4]arene [(5,11,17,23-tetrakis[(p-carboxyphenyl)azo]25,26,27,28-tetrahydroxycalix[4]arene)] host species. PPy/azocalix[4]arene salts were characterized by FTIR, TGA, SEM, X-ray diffraction, and conductivity measurements. The properties of PPy were investigated in the presence of azocalix[4]arene host species. The conductivity of PPy increased in the presence of azocalix[4]arene. TGA results indicated that the PPy/azocalix[4]arene salts have higher thermal stability than PPy. It was observed from SEM analysis that the particle diameter of PPy decreased with increasing content of azocalix[4]arene.
