制备方法与用途

用途：科研试剂、生化研究

生产方法： 取10g氧化铒，溶于500mL 50%的醋酸水中，加热使氧化铒完全溶解。若有不溶物，过滤得清液。再将此水溶液置于75℃水浴中，蒸去大部分水分，待结晶析出后进行过滤收集。将晶体置于装有氢氧化钠和高氯酸镁的真空干燥器中抽真空干燥，即可得到四水醋酸铒。

  Benzoic acid nitrogen mustard and its rare earth metal complexes were synthesized and characterized by elemental analyses, IR, electronic spectrum, and EPR. The interaction of synthesized complexes with Ct-DNA was investigated and reviewed as a mixed manner of both intercalation and alkylation via fluorescence titration. Their biological activities were also evaluated in K562 and Vero cell lines, indicating

  process "guest exchange" took place quantitatively when rare earth metals were used as a guest. In the case of alkaline earth metals, selectivity of Ca2+ > Sr2+ > Ba2+ >> Mg2+ was observed. On the other hand, the transmetalation did not take place at all when alkali metals were used for the guest. Accordingly, the trinuclear complex [LZn3]2+ is excellent in discriminating charge of the guest ions. The

  我们设计了一种新型的双 (N2O2) 螯合配体，可在 N2O2 位点的金属化上提供 C 形 O6 位点。UV-vis 和 1H NMR 滴定清楚地表明，H4L 和醋酸锌 (II) 之间的络合通过高度协同的过程提供了 1:3 络合物 [LZn3]2+。尽管双核金属宿主 [LZn2] 的 O6 识别位点充满了额外的 Zn2+，但 O6 位点可以结合客体离子，同时释放最初结合的 Zn2+。当稀土金属被用作客体时，新的识别过程“客体交换”发生在数量上。在碱土金属的情况下，观察到 Ca2+ > Sr2+ > Ba2+ >> Mg2+ 的选择性。另一方面，当碱金属用作客体时，根本没有发生金属转移。因此，三核络合物 [LZn3]2+ 在区分客体离子的电荷方面非常出色。由此获得的金属宿主-客体复合物具有螺旋结构，螺旋的半径 d 和缠绕角θ取决于客体的大小。La3+ 复合物的 theta 最小（288 度），Sc3+

  A new class of lanthanide‐doped upconversion nanoparticles are presented that are without Yb3+ or Nd3+ sensitizers in the host lattice. In erbium‐enriched core–shell NaErF4:Tm (0.5 mol %)@NaYF4 nanoparticles, a high degree of energy migration between Er3+ ions occurs to suppress the effect of concentration quenching upon surface coating. Unlike the conventional Yb3+‐Er3+ system, the Er3+ ion can serve

  提出了一种新型的镧系元素掺杂的上转换纳米粒子，它们在主体晶格中没有Yb 3+或Nd 3+敏化剂。在富含的核壳NaErF 4：Tm（0.5 mol％）@ NaYF 4纳米颗粒中，发生了Er 3+离子之间的高度能量迁移，从而抑制了表面涂层上浓度淬灭的影响。与传统的Yb 3+ -Er 3+系统不同，Er 3+离子既可以用作敏化剂也可以用作活化剂，以实现有效的上转换过程。重要的是，适当掺杂Tm 3+已经证明通过能量俘获进一步增强上转换发光。这使所得的纳米颗粒具有鲜红色（约700倍的增强）和在多个激发波长下均可实现的近红外发光。这是减轻浓度猝灭效应的基本新途径，从而为生物应用中的红色发射上转换纳米探针提供了一种便捷的方法。
