Organic molecular ferroelectric diisopropylammonium chloride (dipaCl) was successfully synthesized using diisopropylamine, hydrochloric acid (57%) and methanol solution. Dielectric permittivity, impedance, modulus spectroscopy and conductivity were systematically studied by Capacitance–Conductance (CP – G) measurements in the temperature range of 373–445 K. Dielectric property tests clearly show that the organic molecular ferroelectric dipaCl obeys Curies–Weiss law 1/e = (T–T0)/C. The real (Z′) and imaginary (Z″) parts of the electrical modulus were calculated from the various values of e′ and e″. It is shown that AC conductivity satisfies the relation s(w) ∞ wn, where the power exponent n depends on temperature and frequency. From Arrhenius equation, the activation energies Es and Eh are also calculated which describes the complete conduction mechanism of dipaCl.
