  二价euro配合物18冠6衍生物的发光

  摘要：

  摘要研究了18冠6及其衍生物的二价euro配合物的发光。发射的量子产率和寿命通过常规方法确定。观察到的发光强度通常非常大，最强的发光强度是由18冠6配合物Eu2 +的甲醇溶液提供的，该溶液的强度是相同Eu32-甲醇溶液的强度的150倍Eu2 +浓度。根据发射寿命和量子产率估算了配合物激发态的辐射速率常数和非辐射速率常数。与冠醚形成复合物时的发射强度增强似乎是由于Eu2 +离子与溶剂分子的紧密接触所造成的绝缘，从而导致了非辐射能的损失。

  Micellar Solutions of Octyl-18-crown-6

  摘要：

  The solution properties of the novel surfactant octyl-18-crown-6 (C-8 Phi(6)) have been investigated with phase diagram, light-scattering, and surface tension measurements. This tenside is made up of an octyl hydrophobic chain attached to a 18-crown-6 ether and cyclic polar head-group that is highly selective for complexing Ki ions. The results show that C-8 Phi(6) produces micellar structures in water and in KCl aqueous solutions, with a radius of about 30 Angstrom. Addition of potassium ions in a molar ratio of 0.4 (KCl/C-8 Phi(6)) increases the hydrophilicity of the surfactant, as shown by the increment of the phase separation temperature, and produces a slight shift in the critical micellar concentration value, as it results from surface tension measurements. The intermicellar interaction parameter alpha, obtained from QELS experiments, has been discussed. Pure C-8 Phi(6) micelles experience attractive intermicellar interactions overimposed to the hard-sphere interactions, while the K+ complexation of the surfactant polar head-groups leads to a decrease of the average attractive component of the interaction. These results show that intermicellar interactions are selectively controlled and modulated by simply adding a proper salt that can be complexed by the polar head-groups of the surfactant.
