Abstract

The ferroelectric behaviour of an octahedral cage [[Ni₆(H₂O)₁₂(TPTA)₈]·(NO₃)₁₂·36H₂O] (1) exhibiting high remnant polarization of 25.31 μC cm⁻² is discovered. For the first time, clear domain structures and the characteristic electromechanical responses are demonstrated using piezoresponsive force microscopy for a thin film of 1. Owing to its mechanical energy conversion capability, polymer composites of 1 were employed as efficient piezoelectric nanogenerators.
