Embodiment Construction
[0019] To synthesize the HL ligand, a mixture of n-BuSn(O)OH (0.030 g, 0.14 mmol), ligand HL (0.100 g, 0.14 mmol), toluene 30 mL, and ethanol 10 mL was placed in a Dean-Stark apparatus It was heated to reflux for 8 hours, and the water formed in the reaction was removed by azeotropic distillation. The solution was then distilled under reduced pressure to obtain a white solid. Recrystallization from chloroform / dichloromethane / toluene solution at room temperature gave colorless crystals with a yield of 53%.
[0020] The main infrared absorption peaks are: 3419 (s), 2972 (m), 2875 (s), 1636 (m), 1459 (w), 1398 (m), 1298 (s), 1208 (m), 1103 (w ), 1019 (w), 918 (m), 873 (s), 731 (m), 622 (m), 586 (m), 540 (s), 499 (m), 444 (m).
