The synthesis of novel fluorescent copper nanoclusters using jatrorrhizine as a template and its potential application in catalysis
The synthesis of fluorescent copper nanoclusters(CuNCs)using non-sulfhydryl small molecule compounds as templates is currently a highly researched topic.In this study,Jatrorrhizine(JAT),a natural isoquinoline alkaloid,was selected as the template and ascorbic acid was utilized as the reducing agent for the synthesis of a novel fluorescent copper nano-cluster(JAT-CuNCs).To achieve the maximum fluorescence of JAT-CuNCs,the dosage of JAT,the concentration of CuSO4,pH,and synthesis time were optimized.The synthesized JAT-CuNCs were characterized using UV-Vis absorption spectroscopy,fluorescence spec-troscopy,fourier transform infrared spectroscopy,and high-resolution transmission electron microscopy.The results indicate that the average size of JAT-CuNCs was 3.5±0.5 nm.with maximum excitation and emission wavelengths at 368 nm and 472 nm,respectively.Moreo-ver,JAT-CuNCs exhibited characteristics of aggregation-induced emission and demonstrated excellent optical stability.Additionally,JAT-CuNCs successfully catalyzed the reduction of methylene blue(MB)by hydrazine hydrate,resulting in the disappearance of the absorption peak of MB at 665 nm within 4.5 min and a color transition from blue to colorless in the so-lution.This study presents a promising material with significant potential for application in catalysis,while also providing valuable insights for the development and utilization of natural products.
