A novel HBT-hemicyanine hybrid was prepared. This hybrid not only displays a large red-shifted (Δλ = 125 nm) emission compared to the well known ESIPT dye HBT, but also can be used as a new probe for rapid, colorimetric and ratiometric fluorescent detection of bisulfite with high selectivity and sensitivity in aqueous solution. The detection limit of this probe for HSO3(-) was calculated to be about 56 nM with a linear range of 0-25 μM. The potential application of this probe was exampled by detection of bisulfite in real food samples and living cells. Overall, this work not only provided a new ratiometric sensing platform, but also provided a new promising colorimetric and ratiometric fluorescent probe for bisulfite.
制备了一种新型的HBT-半菁杂化物。与著名的ESIPT染料HBT相比，这种杂化物不仅显示出大的红移（Δλ = 125 nm）发射，而且还可以用作一种新的探针，用于在水溶液中对亚硫酸氢盐进行快速、比色和比率荧光检测，具有高选择性和灵敏度。该探针对HSO3(-)的检测限计算约为56 nM，线性范围为0-25 μM。通过检测实际食品样品和活细胞中的亚硫酸氢盐举例说明了该探针的潜在应用。总体而言，这项工作不仅提供了一个新的比率传感平台，而且还为亚硫酸氢盐提供了一种新的有前景的比色和比率荧光探针。
