Abstract

Abstract: Organic–inorganic hybrid ferroelectrics are an exciting class of molecular materials with promising applications in the area of energy and electronics. The synthesis, ferroelectric and piezoelectric energy harvesting behavior of a 3d metal ion‐containing A4 BX6 type organic–inorganic hybrid salt [Ph3 MeP]4 [Ni(NCS)6 ] (1 ) is now presented. P‐E hysteresis loop studies on 1 show a remnant ferroelectric polarization value of 18.71 μC cm −2, at room temperature. Composite thermoplastic polyurethane (TPU) devices with 5, 10, 15 and 20 wt % compositions of 1 were prepared and employed for piezoelectric energy harvesting studies. A maximum output voltage of 19.29 V and a calculated power density value of 2.51 mW cm −3 were observed for the 15 wt % 1 ‐TPU device. The capacitor charging experiments on the 15 wt % 1 ‐TPU composite device shows an excellent energy storage performance with the highest stored energies and measured charges of 198.8 μJ and 600 μC, respectively. Abstract : Brand‐new combined harvesters : An organic–inorganic hybrid salt of phosphonium cations and Ni II isothiocyanate ions was synthesized. It exhibits ferroelectric behavior and efficient mechanical energy harvesting and storage capabilities.
