Abstract
Gold is classified as a heavy metal, and its ion (Au3+) can manifest adverse impacts on ecological and human health. Thus, an effective method for Au3+ detection is highly required. In this work, a new [5]helicene-based fluorescence sensor (M202P) was synthesized and applied for Au3+ monitoring in near-perfect aqueous media. M202Prapidly detected Au3+ through a fluorescence quenching response and furnished a large Stokes shift of 157 nm. The Au3+ sensing ability of M202P allowed it to withstand interference from other metal ions, with a detection limit for Au3+ of 8.0 ppb. The mechanism underlying its Au3+ detection was the coordination of Au3+ with the alkyne and carbonyl oxygen, leading to the later hydration of alkynyl moiety, as thoroughly proven by FTIR, 1H NMR, 13C NMR, and HRMS, with the stoichiometric ratio of 1:1 according to Job's plot. In addition, M202P can be used for the quantitative analysis and qualitative fluorescence assay of Au3+ levels in environmental waters and fertilizer solutions. This sensor also demonstrated high potential as a fluorescence tracking agent in human cells and was utilized in fabricating a paper test strip.

Abstract
To achieve real-time monitoring of Au3+, a corn bract cellulose-based fluorescent probe MAC-1 for was synthesized. MAC-1 showed good fluorescence properties in DMF-H2O (1:9, v/v, pH = 7.4) solution, showed a fluorescence emission peak at 520 nm with quenching fluorescence properties for Au3+. The structure of MAC-1 was analyzed by SEM (Sample microstructure images), XRD (X-ray diffraction), FTIR (Fourier transform infrared spectroscopy), 1H NMR, Elemental analysis, EDS, Mapping and TG (Thermogravimetry) were analyzed. The fluorescence properties of the probe were also characterized by UV spectrophotometer and fluorescence spectrophotometer. The results showed that the recognition of Au3+ by the probe MAC-1 exhibited high selectivity and high sensitivity. Moreover, it is highly resistant to interference and has a short response time, which can be rapidly responded within 1 min. In addition, to improve the practical application of the probe, the probe was prepared as a fluorescent composite film and the fluorescence effect shown by the fluorescent composite film is consistent with the fluorescence change of the probe MAC-1 itself. The fluorescent composite film also has excellent selectivity and good overall physical and mechanical properties. This study provides a meaningful reference for the detection of Au3+ and further expands the application field of agroforestry waste.
