摘要: 通过溶剂热合成方法,以吡啶-2-甲醛肟(HPycox)和Ti(OiPr)4合成了双核钛配合物[Ti2μ2-O)(Pycox)2(OiPr)4] (1)。通过结构分析,分别使用二苯基膦酸和苯基膦酸对其进行结构调控,成功制备了三核钛配合物[Ti3μ2-O)2(Pycox)2(Ph2PO22(OiPr)4] (2)和六核钛配合物[Ti6μ2-O)2μ3-O)2(Pycox)2(PhPO34(OiPr)6]·2CH3CN (3)。配合物1~3的光学带隙分别为2.89、3.00和2.87 eV,其中配合物2的光电流密度可达0.1 μA·cm-2

Abstract: [Ti2(μ2-O)(Pycox)2(OiPr)4] (1) was solvothermally synthesized by the reaction of 2-pyridinecarbaldehyde oxime (Hpycox) and Ti(OiPr)4 in a simple and general approach. Interestingly, by analyzing the structure of 1, diphenylphosphinic acid and phenylphosphonic acid were selected respectively to regulate the structure of 1, and[Ti3(μ2-O)2(Pycox)2(Ph2PO2)2(OiPr)4] (2) and[Ti6(μ2-O)2(μ3-O)2(Pycox) 2 (PhPO3)4(OiPr) 6]·2CH3CN (3) were successfully obtained. Moreover, their light absorption behaviors, band gaps, and photocurrent responses were also investigated. The band gaps of complexes 1-3 were 2.89, 3.00, and 2.87 eV, respectively. Among the three complexes, complex 2 exhibited the largest photocurrent density with the value of 0.10 μA·cm-2.
