We report a novel family of lanthanide complexes Ln(DPPOP)3 (Ln = Pr, Nd, Sm, Eu, Tb, Dy, Er, and Yb) employing anionic tridentate (O∧N∧O) ligand 6-(diphenylphosphoryl)picolinate (DPPOP). Crystal structures of the complexes reveal that each lanthanide ion is nine-coordinated by three tridentate ligands. In the crystals, 1D channels are found, which can absorb and eliminate water reversibly. DPPOP possesses high triplet energy and can sensitize a series of lanthanide ions. An energy transfer mechanism is proposed through the higher excited states of the lanthanide ions. In the solid state, remarkably high quantum yields in the visible range are obtained: 81% for Eu(III), 97% for Tb(III), 13% for Dy(III), and 4% for Sm(III) complex.

用6-(二苯基磷酰基)吡啶甲酸酯构造的高发射镧系配合物家族。
我们报告镧系络合物LN(DPPOP)的一个新家族3(Ln为镨,钕,钐,铕,铽,镝,铒,和Yb)采用阴离子三齿(O ∧ Ñ ∧ O)配体6-(二苯基)吡啶甲酸甲酯(DPPOP)。配合物的晶体结构表明,每个镧系元素离子由三个三齿配体九配位。在晶体中,发现了一维通道,该通道可以可逆地吸收和消除水。DPPOP具有很高的三线态能量,可以使一系列镧系离子敏感。通过镧系离子的更高激发态,提出了一种能量转移机制。在固态下,在可见光范围内可获得非常高的量子产率:Eu(III)为81%,Tb(III)为97%,Dy(III)为13%,Sm(III)络合物为4%。
