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 ([Formula: see text] – [Formula: see text] 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/[Formula: see text] = ([Formula: see text]–[Formula: see text]/[Formula: see text]. The real ([Formula: see text] and imaginary ([Formula: see text]) parts of the electrical modulus were calculated from the various values of [Formula: see text] and [Formula: see text]. It is shown that AC conductivity satisfies the relation [Formula: see text], where the power exponent [Formula: see text] depends on temperature and frequency. From Arrhenius equation, the activation energies [Formula: see text]and [Formula: see text] are also calculated which describes the complete conduction mechanism of dipaCl.
