A novel dicyanoisophorone based fluorescent probe HP was developed to detect hydrazine. Upon the addition of hydrazine, probe HP displayed turn-on fluorescence in the red region with a large Stokes shift (180nm). This probe exhibited high selectivity and high sensitivity to hydrazine in solution. The detection limit of HP was found to be 3.26ppb, which was lower than the threshold limit value set by USEPA (10ppb). Moreover, the probe was successfully applied to detect hydrazine in different water samples and living cells.
一种基于二氰异佛酮的新型荧光探针 HP 被开发出来用于检测联氨。当加入联氨时，探针 HP 在红色区域显示出开启的荧光，具有较大的斯托克斯位移（180nm）。该探针在溶液中对联氨表现出高选择性和高灵敏度。发现 HP 的检测限为 3.26ppb，低于 USEPA（10ppb）设定的阈值。此外，该探针成功应用于不同水样和活细胞中联氨的检测。
