“Tb(hfa)3diglyPU” polyurethane compositewas prepared from the complex solution in polyol (22 mmol/l), which was mixed with hexamethylenediisocyanate (1:1 ratio), after vacuum removal of air bubbles, the polymerization was carried out at 60 ◦C. Composites with Eu(ttfa)3phen were obtained analogously (a 0.5 mmol/l polyol solution of complex was used). (b) Vacuum dried complexes (2 mmol) were dissolved in dimethylformamide and added to the hexamethylenediisocyanate (1 g, ratio –OH:NCO or –NH2:NCO approximately 1:100), dimethylformamide was evaporated in vacuum and the complex solution in diisocyanate thus obtained was mixed with the polyol (1:1 ratio), air bubbles were removed under vacuum. The polymerization to give the polyurethane was again carried out at 60 ◦C. The emission intensities (not quantum yields) were at a maximum at approximately 10−2 mol complex/L. 求翻譯這兩段話 |

“三(六氟乙酰丙酮)雙聚氨酯合鋱”聚氨酯復(fù)合材料是通過(guò)在多元醇的混合溶液(22mmol/L)中混入己二異氰酸酯(比例為1:1)制備而成的，真空除去氣泡后，聚合反應(yīng)在60℃下進(jìn)行。三(噻吩甲酰三氟丙酮)苯酚合銪復(fù)合材料通過(guò)類似方法(使用0.5mmol/L多元醇的混合溶液)制備而成。 (b)真空干燥的混合物(2mmol)溶于二甲基甲酰胺并添加到己二異氰酸酯(1g,–OH:NCO或–NH2:NCO約為1:100)中、二甲基甲酰胺由真空蒸發(fā)除去，這樣就得到了混有多元醇(比例為1:1)的二異氰酸酯混合溶液，氣泡在真空條件下被除去。聚氨酯的聚合反應(yīng)在60℃下再次進(jìn)行。發(fā)射強(qiáng)度(非量子產(chǎn)率)達(dá)到最大值，約為10−2 mol/L。 |
