当将全氟己烷气体引入空气中并自支撑在C 2 F 5标记的化合物的水溶液上的磷脂膜上方时,会导致后者的募集和固定在界面膜中。当磷脂形成液体浓缩的吉布斯单层时(二棕榈酰磷脂酰胆碱(DPPC)就是这种情况),除去F-己烷后,C 2 F 5标记的分子仍保留在单层中。研究涉及气泡轮廓分析张力测定法(Gibbs膜),Langmuir单层膜和微泡实验。利用新现象来整合缺氧生物标志物C 2 F 5在微泡壳中标记的亚硝基咪唑(EF5)。这一发现为氟化治疗分子和生物标志物的传递开辟了前景。
EF5 (a 2-nitroimidazole containing an N-(pentafluoropropyl) acetamide substituent) is a very sensitive probe for quantifying the amount of hypoxia within cells; a much improved, short step, synthetic procedure is described for EF5, whose X-ray structure is also presented.

Perfluorohexane gas when introduced in the air atmosphere above a film of phospholipid self‐supported on an aqueous solution of C2F5‐labeled compounds causes the recruitment and immobilization of the latter in the interfacialfilm. When the phospholipid forms a liquid‐condensed Gibbs monolayer, which is the case for dipalmitoylphosphatidylcholine (DPPC), the C2F5‐labeled molecule remains trapped in
