    Preparation of all N-coordinated zirconium amide amidinates and studies of their reactions with dioxygen and water
    摘要:
    Zr(NR2)(2)[MeC((NPr)-Pr-i)(2)](2) (R = Me, 1; Et, 2) have been prepared through aminolysis and their reactions with O-2 and water have been studied. Two major products from the reactions are the oxo dimer {(mu-O)Zr[MeC((NPr)-Pr-i)(2)](2))(2) (3) and its insoluble polymer {(mu-O)Zr[MeC((NPr)-Pr-i)(2)](2)}(n) (4). Over time the dimer 3 polymerizes to 4. Zr peroxo trimer {(mu-eta(2):eta(2)-O-2)Zr[MeC((NPr)-Pr-i)(2)](2)}(3) (5) was also observed from the reaction of 1 with O-2 and its crystal structure is reported. DFT calculations show that the reaction of 1 with O-2 follows a radical process, yielding the peroxo trimer 5. Mass spectrometric studies of the reactions of water in air with 1 and 2 show the formation of the oxo monomer (O=)Zr[MeC((NPr)-Pr-i)(2)](2) (6), oxo dimer {(mu-O)Zr[MeC((NPr)-Pr-i)(2)](2)}(2).(3), and the dihydroxy monomer (HO)(2)Zr[MeC((NPr)-Pr-i)(2)](2) (7). In addition, the cations (Zr(NR2)[MeC((NPr)-Pr-i)(2)](2)}(+) (R = Me, Et) Were observed. 2 revealed an interesting dynamic NMR behavior. Variable-temperature (VT) NMR spectroscopy has been used to study the Bailar twist process in 2, giving activation parameters Delta H-double dagger = 10.9(1.1) kcal mol(-1), Delta S-double dagger = -11(4) eu and Delta G(303 kappa)(double dagger) = 14(2) kcal mol(-1).

    作为原子层沉积前驱体的胍基和脒基铈镱配合物的合理开发:合成、建模和应用
    摘要:
    由于用于含稀土薄膜材料气相沉积的合适前体的可用性有限,因此人们寻求新的或改进的前体。在这项研究中,我们探索了含铈 (Ce) 和镱 (Yb) 薄膜的原子层沉积 (ALD) 的新前驱​​体。合成了一系列铈 (Ce) 和镱 (Yb) 的均配三胍盐和三脒酸盐配合物,并进行了彻底表征。N-C-N主链上的C-取代基(Me、NMe 2、NEt 2,其中Me=甲基,Et=乙基)和N-取代基从对称异丙基(i Pr)到不对称叔丁基(t Bu) 和 Et 被系统地改变以研究取代基对所得化合物的物理化学性质的影响。[Ce(dpdmg) 3 ] 1和 [Yb(dpdmg) 3 ] 6 (dpdmg= N,N' -二异丙基-2-二甲基酰胺基胍)的单晶结构突出了固态中的单体性质,具有扭曲的三角晶系棱柱几何。热重分析表明,配合物具有挥发性,并强调配合物中不对称性的增加会降低其熔点,同时降低其热稳定性。密度泛函理论(DFT
