検討1
1−1.希土類化合物の合成
ホスフィンオキシド配位子Fdpbp
下記反応式に従って、ホスフィンオキシド配位子Fdpbpを合成した。
1H-NMR:(270 MHz, CDCl3, 25℃) δ 7.76-7.85 (8H, Ar), 7.59-7.66 (4H , Ar),7.50-7.58 (8H , Ar) ppm.
IR (ATR) : 1243 cm-1(st, P=O)
ナス型フラスコにFdpbp(349.6mg, 0.5 mmol)を入れ、これを加熱したクロロホルム(20 mL)に溶解させた。別の容器内でEu(hfa)3(H2O)2(406.8 mg, 0.5 mmol)をメタノール(20 mL)に溶解させた。そのメタノール溶液をFdpbpのクロロホルム溶液に滴下し、12時間加熱還流した。その後、反応液からの再結晶により、Eu2(hfa)6(Fdpbp)2(無色透明結晶、300 mg、収率41%)を得た。
IR (KBr) : 1655 cm-1 (st, C=O),1255 cm-1 (st, P=O)
ESI-MS mass m/z = 2965.92 [M+Na]+
Eu2(hfa)6(Fdpbp)2の単結晶のX線回析の結果から、2個のEuイオンに結合したホスフィンオキシド配位子Fdpbpの2個のテトラフルオロフェニレン基が、上記式に示されるように互い違いにねじれた向きで配置されている安定した構造が形成されていることが示唆された。
図1は、Eu2(hfa)6(Fdpbp)2の熱重量・示差熱分析の結果を示すグラフである。Eu2(hfa)6(Fdpbp)2が300℃を超える高い分解温度を示すことが確認された。
Eu2(hfa)6(Fdpbp)2の発光励起スペクトルを測定した。図2は、Eu2(hfa)6(Fdpbp)2の25℃における発光励起スペクトルである。さらに、200℃における発光スペクトルも測定した。図3は、25℃及び200℃におけるEu2(hfa)6(Fdpbp)2の発光スペクトルである。Eu2(hfa)6(Fdpbp)2は、200℃において、常温での値と比較して70%以上の発光強度を維持した。
2―1.希土類化合物の合成
希土類化合物Tb2(hfa)6(Fdpbp)2
ナス型フラスコにFdpbp(349.6mg, 0.5 mmol)を入れ、これを加熱したクロロホルム(20 mL)に溶解させた。別の容器内でTb(hfa)3(H2O)2(407.0 mg, 0.5 mmol)をメタノール(20 mL)に溶解させた。そのメタノール溶液をFdpbpのクロロホルム溶液に滴下し、12時間加熱還流した。その後、反応液からの再結晶により、Tb2(hfa)6(Fdpbp)2(無色透明結晶、350 mg、収率47%)を得た。
IR (KBr) : 1655 cm-1 (st, C=O),1253 cm-1 (st, P=O)
ESI-MS mass m/z = 2979.92 [M+Na]+
ナス型フラスコにFdpbp(349.6mg, 0.5 mmol)を入れ、これを加熱したクロロホルム(20 mL)に溶解させた。別の容器内でYb(hfa)3(H2O)2(407.5 mg, 0.5 mmol)をメタノール(20 mL)に溶解させた。そのメタノール溶液をFdpbpのクロロホルム溶液に滴下し、12時間加熱還流した。その後、反応液からの再結晶により、Yb2(hfa)6(Fdpbp)2(無色透明結晶、270 mg、収率35%)を得た。
IR (KBr) : 1653 cm-1 (st, C=O),1253 cm-1 (st, P=O)
Tb2(hfa)6(Fdpbp)2及びYb2(hfa)6(Fdpbp)2の25℃における発光スペクトル(励起光:350nm)を測定した。図5は、Eu2(hfa)6(Fdpbp)2、Tb2(hfa)6(Fdpbp)2及びYb2(hfa)6(Fdpbp)2の25℃における発光励起スペクトルである。Tb化合物は緑色、Eu化合物は赤色、Yb化合物は赤外域の発光を示した。
