Abstract:
The X‐site ion in organic–inorganic hybrid ABX 3 perovskites (OHPs) varies from halide ion to bridging linkers like HCOO − , N 3 − , NO 2 − , and CN − . However, no nitrite‐based OHP ferroelectrics have been reported so far. Now, based on non‐ferroelectric [(CH 3 ) 4 N][Ni(NO 2 ) 3 ], through the combined methodologies of quasi‐spherical shape, hydrogen bonding functionality, and H/F substitution, we have successfully synthesized an OHP ferroelectric, [FMeTP] [Ni(NO 2 ) 3 ] (FMeTP =N ‐fluoromethyl tropine). As an unprecedented nitrite‐based OHP ferroelectric, the well‐designed [FMeTP][Ni(NO 2 ) 3 ] undergoes the ferroelectric phase transition at 400 K with an Aizu notation of 6/ mmm F m , showing multiaxial ferroelectric characteristics. This work is a great step towards not only enriching the molecular ferroelectric families but also accelerating the potential practical applications.
