Research Abstract

最近接のEu^<3+>…Eu^<3+>距離がそれぞれ5.02、6.12、3.76Åの〔Eu_3(H_2O)_3(SbW_9O_<33>)(W_5O_<18>)_3〕^<18->、〔Eu_4(MoO_4)(H_2O)_<16>(Mo_7O_<24>)_4〕_<14->,{〔Eu_3O(OH)_3(H_2O)_3〕_2Al_2(Nb_6O_<19>)_5}^<26->をこれまで見い出してきた。これら3種類のポリ酸の中でEu^<3+>が占めるサイトの一部をTb^<3+>に置換したTb^<3+>/Eu^<3+>の混合ポリ酸,TbEu_<12>,TbEu_3,Tb_5Euをそれぞれ合成しキャラクタリゼーションを行った後Tb^<3+>→Eu^<3+>への分子内エネルギー移動の動力学を明らかにし構造解析結果と合わせて議論された。
負の溶解度-温度依存性を示すポリエチレンオキシドオリゴマーを溶媒として希土類塩の分離を試みる中で適切な分子量のポリエーテルを溶媒として特定の希土類塩が選択的に効率良く分離できることを明らかにした。例えばトリエチレングリコールにSmCl_3・6H_2O,LaCl_3・6H_2Oを溶解させた場合高温側ではLaCl_3のみが析出した。またNdCl_3・6H_2Oとジエチレングリコール(DEG)錯体,Nd(DEG)_3Cl_3の構造を明らかにした。
一連の希土類金属を含むサンドイッチ型フタロシアニン錯体の光エネルギー移動、電子移動過程を時間分解温度吸収スペクトル測定ににより明らかにした。
