“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. 求翻译这两段话 |

“三(六氟乙酰丙酮)双聚氨酯合铽”聚氨酯复合材料是通过在多元醇的混合溶液(22mmol/L)中混入己二异氰酸酯(比例为1:1)制备而成的，真空除去气泡后，聚合反应在60℃下进行。三(噻吩甲酰三氟丙酮)苯酚合铕复合材料通过类似方法(使用0.5mmol/L多元醇的混合溶液)制备而成。 (b)真空干燥的混合物(2mmol)溶于二甲基甲酰胺并添加到己二异氰酸酯(1g,–OH:NCO或–NH2:NCO约为1:100)中、二甲基甲酰胺由真空蒸发除去，这样就得到了混有多元醇(比例为1:1)的二异氰酸酯混合溶液，气泡在真空条件下被除去。聚氨酯的聚合反应在60℃下再次进行。发射强度(非量子产率)达到最大值，约为10−2 mol/L。 |
