In recent years, fluorescent organic-inorganic hybrid nanomaterials have received much interest as potential fluorescent sensor materials. In this study, fluorescent organic-inorganic hybrid nanomaterials (POSS@ANT) were created using polyhedral oligomeric silsesquioxane as the precursor and 9,10-bromoanthracene as the monomer. The morphol. and composition of POSS@ANT, as well as its pore characteristics and fluorescence properties were studied. POSS@ANT displayed steady fluorescence emission at an excitation wavelength of 374 nm. Next, a β-carotene fluorescence sensor was developed using the capacity of β-carotene to quench the fluorescence of POSS@ANT. The quenching process is linked to acceptor electron transfer and energy transfer, and the sensor has a high selectivity for β-carotene. This β-carotene fluorescence anal. method that we established has a linear range of 0.2-4.3 mg/L and a detection limit of 0.081 mg/L. Finally, it was used to quantify β-carotene in health products, the recovery rate was 91.1-109.9%, the relative standard deviation (RSD) was 2.2-4.3%, and the results were comparable with the results of high-performance liquid chromatog. The approach is reliable and can be used to determine β-carotene in health products. The results came from multiple reactions, including the reaction of 9,10-Dibromoanthracene(cas: 523-27-3Quality Control of 9,10-Dibromoanthracene)
9,10-Dibromoanthracene(cas: 523-27-3) is a dibrominated polycyclic aromatic hydrocarbon (PAH). 9,10-Dibromoanthracene is often used as an energy acceptor and activator in reactions that produce chemiluminescence.Quality Control of 9,10-Dibromoanthracene
