利用色烯衍生物7-硝基-2,3-二氢-1H-环戊二烯并[B]色烯-1-酮(1)合成了一种新的含巯基的比色探针。该分子表现出高选择性和灵敏度,用于检测巯基物质,如半胱氨酸,同型半胱氨酸,谷胱甘肽在水溶液中,通过快速的视觉颜色变化从无色到黄色。
A new thiol-containing colorimetric probe has been developed by using a chromene derivative, 7-nitro-2,3-dihydro-1H-cyclopenta[b]chromen-1-one (1). The molecule exhibited high selectivity and sensitivity for detecting thiol species as cysteine, homocysteine, and glutathione in aqueous solution through a rapid visual color change from colorless to yellow.
