Two analogues of the membrane-forming species
PhCH2SS(C24H40O14)(C20H41)
(1) have been prepared via short synthetic routes. The compounds readily form
self-assembled monolayers on gold.
PhCH2SS(C27H45O16)(C20H41)2
PhCH2SS(C29H48O17)(C20H41)3
Pyrolysis of chlorophyll-a preheated at 250 °C has been carried out to investigate the precursor of 1-pristene often observed in pyrolysis products of kerogens. The 1-pristene/(phytadienes + phytene) ratio increased with increasing preheating time, suggesting the significance of the moiety derived from chlorophyll as the precursor of 1-pristene.
叶绿素 a 在 250 °C 下预热已进行热解,以研究在干酪根热解产物中经常观察到的 1-pristene 前体。1-pristene/(phytadiene + phytene) 比率随着预热时间的增加而增加,表明叶绿素衍生的部分作为 1-pristene 的前体的重要性。
