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.

Abstract: Hybrid perovskite materials are famous for their great application potential in photovoltaics and optoelectronics. Among them, lead‐iodide‐based perovskites receive great attention because of their good optical absorption ability and excellent electrical transport properties. Although many believe the ferroelectric photovoltaic effect (FEPV) plays a crucial role for the high conversion efficiency, the ferroelectricity in CH 3 NH 3 PbI 3 is still under debate, and obtaining ferroelectric lead iodide perovskites is still challenging. In order to avoid the randomness and blindness in the conventional method of searching for perovskite ferroelectrics, a design strategy of fluorine modification is developed. As a demonstration, a nonpolar lead iodide perovskite is modified and a new 2D fluorinated layered hybrid perovskite material of (4,4‐difluorocyclohexylammonium) 2 PbI 4 , 1 , is obtained, which possesses clear ferroelectricity with controllable spontaneous polarization. The direct bandgap of 2.38 eV with strong photoluminescence also guarantees the direct observation of polarization‐induced FEPV. More importantly, the 2D structure and fluorination are also expected to achieve both good stability and charge transport properties. 1 is not only a 2D fluorinated lead iodide perovskite with confirmed ferroelectricity, but also a great platform for studying the effect of ferroelectricity and FEPV in the context of lead halide perovskite solar cells and other optoelectronic applications.

Abstract: On the path of persisting Moore's Law, one of the biggest obstacles is the “Boltzmann tyranny”, which defines the lower limit of power consumption of individual transistors. Negative capacitance in ferroelectrics could provide a solution and has garnered significant attention in the fields of nanoelectronics, materials science, and solid‐state physics. Molecular ferroelectrics, as an integral part of ferroelectrics, have developed rapidly in terms of both performance and functionality, with their inherent advantages such as easy fabrication, mechanical flexibility, low processing temperature, and structural tunability. However, studies on the negative capacitance in molecular ferroelectrics are limited. In this study, we focused on the fabricated high‐quality thin films of trimethylchloromethyl ammonium trichlorocadmium(II) and conducted a pioneering investigation on their negative capacitance responses. Our findings demonstrate that the negative capacitance exhibited by molecular ferroelectrics is comparable to that of conventional HfO 2 ‐based ferroelectrics. This underscores the potential of molecular material systems for next‐generation electronic devices. This article is protected by copyright. All rights reserved

Abstract: Achieving a periodic domain structure in ferroelectric materials to tailor the macroscopic properties or realize new functions has always been a hot topic. However, methods to construct periodic domain structures, such as epitaxial growth, direct writing by scanning tips, and the patterned electrode method, are difficult or inefficient to implement in emerging molecular ferroelectrics, which have the advantages of lightweight, flexibility, biocompatibility, etc. An efficient method for constructing and controlling periodic domain structures is urgently needed to facilitate the development of molecular ferroelectrics in nanoelectronic devices. In this work, it is demonstrated that large‐area, periodic and controllable needle‐like domain structures can be achieved in thin films of the molecular ferroelectric trimethylchloromethyl ammonium trichlorocadmium (TMCM‐CdCl 3 ) upon the application of tensile strain. The domain evolution under various tensile strains can be clearly observed, and such processes are accordingly identified. Furthermore, the domain wall exhibits a superior piezoelectric response, with up to fivefold enhancement compared to that of the pristine samples. Such large‐area tunable periodic domain structure and abnormally strong piezoresponse are not only of great interests in fundamental studies, but also highly important in the future applications in functional molecular materials.
