Outline of Research at the Start

本研究では、平均原子価(AV相) と混合原子価(MV相) という二種類の電子状態が競合している擬一次元ハロゲン架橋金属錯体(MX錯体)と呼ばれるナノワイヤー金属錯体に着目する。AV相は、他に類を見ない「一次元強相関電子系」となるはずであるが、AV相の実現は一部の例に限られていた。そこで、我々が近年開発したいくつかの化学的手法により、最も機能性や構造設計性に優れると予想されるPt錯体でもAV相を実現する。また、この錯体のヘテロ接合における界面の電子状態と物性の解明、多孔性の導入による化学ドーピングの実現にも取り組む。これにより、世界最大の三次非線形光学応答などの革新的機能の創出に挑む。

Outline of Annual Research Achievements

固体の新しい電子状態の発現は新しい機能の発見に繋がり、新しい学問分野の開拓を促してきた。本研究では、ハロゲン架橋金属錯体（MX錯体）の未踏の電子状態にひそむ新しい機能の創出を目的とし、本年度はテーマ１のPt(III)AV相の実現による革新的電子物性の創出に関して重点的に検討した。
対アニオンに脂肪族長鎖を持つアスパラギン酸イオンを導入した[Pt(en)2I](asp-Cn)2-H2OはMV相であるが、アルキル鎖長n = 12の錯体はこれまで報告されているPt-I錯体で最もPt-Pt距離が短くAV相に近かった。そこで、アルキル鎖のファンデルワールス力を高めたアルキル鎖長n = 13, 14のPtのMX錯体を新規合成した。長いアルキル鎖のため結晶性が悪く、非常に薄いフィルム状の固体として得られ、リートベルト法によって構造を明らかにした。室温から5 Kまでの赤外吸収スペクトルを測定し、全ての温度においてPt(III)のAV相を示すシングルピークのN-H伸縮振動が現れることを明らかにした。PtのMX錯体は100年ほど前から合成されているが、本成果が初めてAV相を実現した。
また、対アニオンにヨウ化物イオンを有するPt錯体を合成したところ、MX二量体である[Pt2(en)4I3]I3が得られた。単結晶X線構造解析および顕微反射スペクトル測定により、二量体錯体の２つのPtは等価のPt(III)であることが明らかになった。興味深いことに、この錯体の単結晶は見た目は光沢のあるエメラルドグリーンだが、透過光で見ると赤色である。これは、この化合物のI-Pt-I-Pt-I軸の電荷移動遷移に基づく高い反射率に起因することが分かった。また、DFT計算からPt(III)状態の安定化にPt-I-Ptの三中心四電子結合が大きく寄与していることが明らかになった
