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

Abstract

Polypyrrole (PPy) was doped with the azocalix [4]arene [(5,11,17,23-tetrakis[(p-carboxyphenyl)

Template-free synthesis of an electroactive Au-Calix-PPY nanocomposite for electrochemical sensor applications

“…Moreover, Au-PPY ( prepared via a blank reaction of HAuCl 4 and pyrrole without the calix) was prepared herein for comparison, but such material tended to aggregate, and was relatively unstable for modifying electrodes. 43…”
