以二氰基异佛尔酮为荧光探针，合成了一种检测肼的荧光探针HP。在加入肼后，probeHP在红色区域显示具有大的斯托克斯位移（180 nm）的开启荧光。该探针对肼具有高选择性和高灵敏度。HP的检出限为3.26ppb，低于美国环保局规定的阈值（10ppb）。该探针成功地应用于不同水样和活细胞中肼的检测。
A novel dicyanoisophorone based fluorescent probeHPwas developed to detect hydrazine. Upon the addition of hydrazine, probeHPdisplayed turn-on fluorescence in the red region with a large Stokes shift (180 nm). This probe exhibited high selectivity and high sensitivity to hydrazine in solution. The detection limit ofHPwas found to be 3.26 ppb, which was lower than the threshold limit value set by USEPA (10 ppb). Moreover, the probe was successfully applied to detect hydrazine in different water samples and living cells.
