We propose a new, simple and general procedure of light-driven deoxygenation of solutions based on hydroperoxides formation upon irradiation. Efficient and fast removal of molecular oxygen is caused by photosensitized generation of singlet oxygen, which then reacts with the solvent (2-methyltetrahydrofuran or tetrahydrofuran). Oxygen depletion makes it possible to observe processes normally undetectable in non-degassed liquid samples at room temperature, such as phosphorescence and triplet-triplet annihilation. The potential of the proposed protocol is demonstrated by recording of previously unknown phosphorescence of palladium complex of octaethylporphycene.

光诱导从溶液中去除分子氧


我们提出了一种新的、简单的、通用的基于照射时形成氢过氧化物的光驱动溶液脱氧程序。高效、快速地去除分子氧是由光敏产生单线态氧引起的，单线态氧随后与溶剂（2-甲基四氢呋喃或四氢呋喃）反应。氧消耗使得在室温下可以观察到在未脱气液体样品中通常无法检测到的过程，例如磷光和三重态-三重态湮灭。通过记录以前未知的八乙基卟啉钯络合物的磷光来证明所提出的方案的潜力。
