利用光电离反射飞行时间质谱（PI−ReTOF−MS）沿着电子结构计算，我们报道了在低温甲基膦酸样品的热处理过程中通过缩合反应形成环状甲基膦酸三聚体[c-（CH 3 PO 2）3]。环状甲基膦酸三聚体在固态下形成，并在单光子电离后在气相中与其质子化物质一起检测。我们的研究提供了对含磷的潜在益生元分子的制备的理解，以及在地外环境中低温磷化学的基本知识。
We report the formation of the cyclic methylphosphonic acid trimer [c‐(CH3PO2)3] through condensation reactions during thermal processing of low‐temperature methylphosphonic acid samples exploiting photoionization reflectron time‐of‐flight mass spectrometry (PI−ReTOF−MS) along with electronic structure calculations. Cyclic methylphosphonic acid trimers are formed in the solid state and detected together with its protonated species in the gas phase upon single photon ionization. Our studies provide an understanding of the preparation of phosphorus‐bearing potentially prebiotic molecules and the fundamental knowledge of low‐temperature phosphorus chemistry in extraterrestrial environments.
