Abstract:The naphthalene derivative fluorescent probe F6 was synthesized and a 1 × 10−3 mol/L solution of Al3+ and other metals to be tested was prepared for the subsequent experiments. The Al3+ fluorescence system of the naphthalene derivative fluorescent probe F6 was successfully constructed as demonstrated by fluorescence emission spectroscopy. The optimal time, temperature and pH of the reaction were investigated. The selectivity and anti-interference ability of the probe F6 for Al3+ were investigated by fluorescen… Show more
“…Various fields benefit from a diverse array of practical implementations of structures based on naphthalene [1,2]. Imine systems can also be utilized to assemble discrete cyclophanes, double and triple helicates, dimers, trimmers, and grids [3][4][5][6][7][8][9][10][11][12][13]. One of the factors, which could affect these structure properties can be short contact.…”
This study focuses on the synthesis, characterization, and properties of a yellowish, prism-shaped ligand, N,N′-(naphthalene-1,5-diyl) bis(1-(pyridin-2-yl) methanimine). The ligand was synthesized through refluxing 1,5-diaminonaphthalene and pyridine-2-carbaldehyde in extra-pure ethanol, employing X-ray diffraction on single crystal. The crystal is structured with two pyridylimine-binding units linked to a naphthalene. The crystal has a P21/c space group in a monoclinic system. The structure was confirmed through an infrared examination. Computational spectroscopy and theoretical methods were used to investigate the ligand HOMO, LUMO, and charge distribution. Additionally, a Hirshfeld analysis was performed to investigate noncovalent interactions in the crystalline form. The results showed that dispersion forces (H···H) were the primary factor contributing to the arrangement of the ligand molecule, accounting for 45.3% of the total interactions in the absence of hydrogen bonding. Overall, this study provides valuable insights into the synthesis, characterization, and properties of this unique ligand.
