Research Abstract	本研究は、クラスター,超微粒子,その線状集合体,結晶間ないし物質間の境界線,境界面及び表面・界面の微視的構造の制御と評価を行うとともに,その工学的応用を探ることを目的としている.本研究で得られた新たな知見を以下に列記する. 1.分子構造と電子状態との関連を分子集合体レベルで解明するため,種々の炭素の固体状態での電子遷移を拡散反射法を用いて測定した.その結果,分状に孤立した多環芳香族化合物のスペクトルと積層構造のスペクトルを分離して評価することが可能となった. 2.in situ Raman分光法およびin situ XRD分光法を用いて,リチウムの電気化学的インターカレーションに伴うグラファイト電極の構造変化や表面での副反応を検討した.その結果,プロピレンカーボネートとエチレンカーボナートの混合溶媒を用いた系では可逆なインターカレーション/デインターカレーションを反映したステージ構造やスタッキング変化が認められたが,プロピレンカーボネート単独溶媒系では,不可逆な溶媒の分解にともない電極の欠陥が増大し,その後表面層がはがれ落ちる傾向が明らかとなった. 3.層状ペロブスカイト構造およびマグネトプランバイト構造の2次元層骨格を有する酸素酸塩を合成し,その光学特性に関して検討を行ったところ,吸収エネルギーの発光順位への伝達過程における2次元性が,特徴的な発光スペクトルの変化や蛍光寿命極性を原因となっていることが明らかとなった.
