基于二硫键的多分析物传感器呈现针对Al 3+、Zn 2+和F-离子的独特发射光谱。配体表现出不同类型的相互作用，这三种不同的离子导致在三个不同的波长的荧光强度增强。通过吸收光谱、发射光谱和1H-1 NMR滴定实验对传感过程进行了详细研究。该配体在包括生理pH在内的较宽pH范围内具有工作能力，对HeLa细胞内的Al ~（3+）和Zn ~（2+）具有良好的敏感性。
A dialdehyde-based multi-analyte sensor renders distinctive emission spectra for Al3+, Zn2+ and F- ions. The ligand exhibited different types of interactions with these three different ions resulting in the enhancement of fluorescence intensity at three different wavelengths. All the sensing processes were studied in detail by absorption spectroscopy, emission spectroscopy and H-1-NMR titration experiment. The ligand has the working ability in a wide pH range including the physiological pH. The ligand is nontoxic and amicable for sensing intracellular Al3+ and Zn2+ in live HeLa cells.
