Nature Communications, Volume：12, Number：1, Dec. 2021, [Reviewed]Abstract Organic ferroelectrics, in which the constituent molecules retain remanent polarization, represent an important topic in condensed-matter science, and their attractive properties, which include lightness, flexibility, and non-toxicity, are of potential use in state-of-the-art ferroelectric devices. However, the mechanisms for the generation of ferroelectricity in such organic compounds remain limited to a few representative concepts, which has hitherto severely hampered progress in this area. Here, we demonstrate that a bowl-to-bowl inversion of a relatively small organic molecule with a bowl-shaped π-aromatic core generates ferroelectric dipole relaxation. The present results thus reveal an unprecedented concept to produce ferroelectricity in small organic molecules, which can be expected to strongly impact materials science.

The authors have already reported on an originally designed (sigma+pi)-double aromatic compound that has a sigma-aromatic moiety on the periphery of a benzene platform. In this study, to generalize the concept of (sigma+pi)-double aromaticity, we have synthesized a variety of (sigma+pi)-double aromatic compounds that bear heavy atoms on the periphery of a central benzene ring. We have newly designed and synthesized compounds bearing (sigma+pi)-mixed conjugation systems, where a sigma-delocalized system can interact with a coplanar pi-delocalized system. We have found that non-bonded interactions between heavy chalcogen atoms on the periphery of a benzene ring can regulate properties of the compounds.

This research project focused on the construction of international joint research network, "π-Hub", as a part of the Grant-in-Aid for Scientific Research on Innovative Areas "π-Figuration". To promote active international research exchanges, we supported the invitations of overseas researchers as well as the short-term stays of domestic researchers in overseas research groups. We also organized and supported international symposiums, which were held in overseas research organizations. Through these efforts, joint researches with a total of 40 overseas research institutes with researchers from 17 countries were carried out, and thus, we have formed a tight and strong π-Hub network.

We have focused on the reactivity of a zero-valent main group compounds stabilized by a butadiene as a 4pi electron donor that we have already synthesized and is still the only one example of a zero-valent main group compounds stabilized by a butadiene ligand. We have found a unique ligand exchange reaction in the zero-valent tin compound, which is normally observed in the zero-valent transition-metal compounds. The stability of the zero-valent tin compounds is highly dependent on substituents on the carbon atoms. We have also succeeded in the synthesis of the first example of a zero-valent lead compound stabilized by a butadiene ligand.

We have accomplished the creation of pi-systems that cannot be accessed by the use of only carbon atoms but can be synthesized by taking advantage of heavy main group atoms, which adopt a wide variety of structures and exhibit a wide variety of reactivities. We have succeeded in the creation of a out-of-plane anisotropic pi-conjugated compound by the introduction of phosphorus functionalities. We have demonstrated a bowl-to-bowl inversion of a pi-conjugated compound bearing long C-main group atom bonds as a new strategy for the creation of organoferroelectric compounds. We have succeeded in the synthesis of a coordination polymer by the use of a vacant orbital of a divalent tin compound and a wide variety of transition-metal complexes that bear unique electronic structures derived from an aromatic dianionic tin compound.

The reactions of dilithio-stannoles and a -plumbole, which are dianionic aromatic compounds, with transition-metal reagents afforded transition-metal complexes bearing stannole and plumbole ligands. The structures of thus obtained complexes were determined by X-ray diffraction analysis and their unique electronic characteristics and properties were evaluated. The reaction using the plumbole complex as a catalyst was found.

To activate dinitrogen molecule by main group compounds, an unprecedented main group element-dinitrogen complex should be necessary. In this work, we targeted a lithiostannylene and a silacyclopentadienylidene that were predicted to form stable complexes with dinitrogen molecules. Reduction of Cp*SnCl with lithium did not afford the targeted Cp*SnLi, which was thought to be thermally unstable. We nest chose 3,5-dimesitylphenyl group as a steric protection group succeeded in the synthesis of a dichlorosilole, which is stable under air. The generation of a silacyclopentadienylidene was achieved by the reduction of thus-obtained dichlorosilole with potassium graphite.

We designed hexasila[6]circulene, which is composed of six annulated siloles of importance in the field of materials science, and hexathia[6]circulene, which has a bowl-shaped structure with six annulated thiophenes. According to theoretical calculations, they are predicted to have low-lying LUMOs and small HOMO-LUMO gaps, compared to those of trisilasumanenes that we have already reported, being envisioned to be useful building blocks for important functional molecules. We tried to prepare the designed molecules and succeeded in the synthesis of their promising precursors.

Reduction of aluminum trichloride-N-heterocyclic carbene adduct with lithium naphthalenide afforded dichloroaluminum radical, the formation of which was evidenced by a trapping experiment. Reduction of N-heterocyclic carbene adduct of dichloroalumane bearing a bulky silyl substituent provided an unexpected compound through migration of an aluminum moiety and elimination of a substituent on the nitrogen atom. Debrominative reactions of1,2-bis(phenylseleno)benzene dibromide with tribromoborane and Ag reagents gave bromoselenonium cation and unexpected selenanthrenium cations, respectively.

Transmetalation reactions of tritellurosilane, trisilylsilane and trisilylgermane afforded the corresponding monolithio species. Reinvestigation on the transmetalation reaction of trisilylstannane provided lithiostannane, which surprisingly reacted as a trianion equivalent. Germyldichlorophosphine derived from lithiogermane reacted with potassium t-butoxide to afford phosphagermavinylidene dimer, suggesting that formation of an intermediary germanium-phosphorus triple-bonded compound.
