to class I (L1 and L2) and class II (L3 and L4), respectively. In class I, the boron unit is conjugated with the phenyl linker and the diketone backbone, while in class II, the boron unit, the linker unit, and the diketone unit are nonconjugated with a mutually orthogonal arrangement. To understand the impact of the location of the BMes2Ar unit on the electronic properties of the 1,3-diketone molecules
已经研究了四个BMes 2 Ar(Mes =均三基,Ar =苯基或duryl)官能化的1,3-二酮基
配体,用于Tb(III)和Eu(III)发射的选择性敏化。这些
配体的通式为[R 1 C(O)CR 2 C(O)R 3 ] -(R 1 = Ph,R 2 = H,R 3 = p -Ph-BMes 2,L1; R 1 = R 3 = p -Ph-BMes 2,R 2 = H,
L2; R 1 = R 3 = Me,R 2=p -Ph-BMes 2,L 3; n =1。R 1 = R 3 = Me,R 2 = p -duryl-BMes 2,L4,分别属于I类(L1和
L2)和II类(L3和L4)。在I类中,
硼单元与苯基连接基和二酮主链共轭,而在II类中,
硼单元,连接基和二酮单元互不正交。了解BMes位置的影响2合成并研究了有关1,3-二酮分子的电子性质的Ar单元及其激活
镧系元素发射的能力,并研究了
