Calixarene-Doped Polyaniline for Applications in Sensing

Synthesis of a new type of calixarene-doped polyaniline (PANI) is reported. Polyaniline as a free base (emeraldine) was synthesized by a chemical method, in the presence of HCl and ammonium peroxodisulphate as oxidant. PANI was doped with p-sulfonatocalix|4|arene. The structure of the protonic acid doped- PANI was investigated by infrared and UV-VIS spectroscopies. The spectral features of dopant are found in the doped polyaniline. The synthesized polyaniline exhibits enhanced solubility in dimethyl for mamide and N-methyl pyrrolidon, which is useful for sensing
