neutral monoporphyrinate ytterbium(iii) complexes [Yb(TPP)(L)(H(2)O)] from their precursor [Yb(TPP)(H(2)O)(3)]Cl is presented, where TPP is 5,10,15,20-tetraphenylporphyrinate dianion and L are the bidentate anions of 8-hydroxylquinoline (HOQ), 1-hydroxyl-7-azabenzotriazole (HBTA), 2-benzimidazolylguanidine (HGBI) and 1,1,1,5,5,5-hexafluoro-2, 4-pentanedione (HHFA). The new complexes were characterized by
从其前体[Yb(TPP)(H(2)O)(3)] Cl制备中性单卟啉ate(iii)配合物[Yb(TPP)(L)(H(2)O)]的方法是所示的TPP为5,10,15,20-四苯基卟啉二价阴离子,L为8-羟基喹啉(HOQ),1-羟基-7-氮杂苯并三唑(HBTA),2-苯并咪唑基胍(HGBI)和1,1的双齿阴离子,1,5,5,5-六氟-2,4-戊二酮(HHFA)。通过元素分析和质谱对新配合物进行了表征。通过单晶X射线衍射确定[Yb(TPP)(OQ)(H(2)O)]的结构,揭示中心central(iii)离子为七个坐标。这些复合物的Yb(iii)的近红外发射效率和寿命得以提高,这是由于两个水分子被双齿阴离子取代所致。
