<非特許文献5>清水 洋,“カラムナー液晶 その多様な分子構造と分子間相互作用”,液晶,2002,Vol.6,147-159
電界の印加により立体構造が変化して機能を発現する分子素子の機能の一例として、スイッチング動作が考えられる。図1は、金属イオン3と、側鎖5を有する円盤状に近い有機分子2とが錯体4を形成してなる機能性分子素子1を例として、機能性分子素子1に電界の印加時に金属イオン3の周辺で起こる変化をモデル化して概略図示したものである。
ここでは、カラム状配列構造体を形成する円盤状に近い有機金属錯体分子1として、図2に用いたビラディエノン2と、金属イオン3としての亜鉛(II)イオンとの錯体を用い、図4に示すように、これを組み込んだ電界効果型分子デバイス21及びその作製工程を説明する。
動作の単位が分子1個、電子1個であるので、基本的に低消費電力で動作し、上記において使用したビラディエノンでは、室温のエネルギーと比較して一桁上回る程度の超低消費電力である。発熱量が少ないので、高集積化しても、発熱による問題が起こりにくい。
最近の液晶の高速応答性の改善に見られるように、材料や構造を工夫することにより、従来の無機半導体結晶以上の高速応答性も期待できる。
通常の有機化合物の合成では、無機半導体の製造プロセスで使われるような、人体や環境に有害な試薬等をほとんど必要としない。
図5に示した電界効果型分子デバイス21を作成した。まず、図2に示したM=Zn、R=−C10H21を有するビラディエノン金属錯体1に制御用の電界を印加するための制御電界印加用の電極31及び36と、導電率を測定するための導電率測定用の電極33及び34を形成した。
実施例1において、ダイオード特性を観測するために、制御電界印加用の電極31及び36の間に電界を印加せず、くし型電極33と34との間に印加するバイアス電圧を増減させて、電流量を測定した。
