A new oligothiophene derivative (3TY) was synthesized, and used as a highly selective hydrazine (NH) chemosensor in ∼100% aqueous solution with "naked-eye" colorimetric and "turn-on" fluorimetric response. This chemosensor 3TY enabled ultrafast and ultrasensitive detection of hydrazine with ultralow detection limit of 1.45 nM (0.04 ppb) in a wide sensing pH range from 6 to 10. The sensing mechanism of 3TY toward hydrazine was strongly and fully confirmed. More importantly, colorimetric paper test strip and solid support silica are easily prepared by 3TY for on-site and real-time detection of hydrazine. Furthermore, 3TY displays many potential applications for detecting NH in environmental water and human urine along with bio-imaging in living HeLa cells.
合成了一种新的寡噻吩衍生物(3TY),并将其用作在约 100%水溶液中具有“肉眼可见”比色和“开启”荧光响应的高选择性肼(NH)化学传感器。这种化学传感器 3TY 能够超快速和超灵敏地检测肼,在检测 pH 值范围从 6 到 10 的宽范围内,检测限低至 1.45 nM(0.04 ppb)。3TY 对肼的传感机制得到了强有力和充分的证实。更重要的是,3TY 很容易制备比色试纸条和固体支撑硅胶,可用于现场和实时检测肼。此外,3TY 还可用于检测环境水和人尿中的 NH 以及在活 HeLa 细胞中进行生物成像等多个潜在应用。
