The ‘old’ chemistry between CO2 and primary alkylamines has been revisited. Amines 1 and 2, with appended aromatic fluorophores, reversibly reacted with CO2 in polar aprotic solvent (e.g. DMSO, DMF) with the formation of carbamic acids 3 and 4. As a result, strong fluorescence occurred, thus directly reporting on the CO2 entrapment. Carbamic acids were studied by 1H and 13C NMR spectroscopy in DMSO-d6
CO 2和伯烷基胺之间的“旧”化学方法已被重新研究。胺1和2以及附加的芳香族荧光团在极性非质子传递溶剂(例如DMSO,DMF)中与CO 2可逆反应,形成氨基甲酸3和4。结果,发生了强烈的荧光,因此直接报告了CO 2的截留。通过1 H和13 C NMR光谱在DMSO- d 6中研究了氨基甲酸。尽管氨基甲酸酯键是共价键,但它是可逆的,在加热或用惰性气体简单闪蒸溶液时可断裂。一氧化碳的合成与评价还报道了2-感测氨基酸-α-萘基甘氨酸7在生物相关条件下在水溶液中监测CO 2的潜力。
