synthesis and characterization of conductive polymers based on carbazole structure and investigation of their physical, electrochemical and sensor properties

A carbazolyl-derived monomer named n-(4-aminophenyl)carbazole was synthesized and then homopolymerized via free radical polymerization using aps as initiator. the powder x-ray diffraction (xrd) analysis, morphological characterizations of samples by fesem and tem, ft-ir ,thermal stability(tga) were investigated.a eletrochemical sensing platform for determining hydrazine in alkaline media based on polycarbazole is introduced. cyclic voltammetry was  and chronoamperometry was done  in a three-electrode system containing an ag,agcl (saturated kcl) as a reference electrode, a pt wire as a counter electrode and a modified gce with 2 mm diameter as the working electrode. electrochemical impedance spectroscopy (eis) was acquired  in a 5 mm k3fe(cn)6/k4fe(cn)6 in 0.1 m kcl as supporting electrolyte in the frequency range from 0.01 hz to100 khz.
