摘要

摘要以Fe3O4@SiO2@Si-Pr-NH-CH2CH2NH2为基本磁性纳米催化剂，以苊马醌和2个吲哚等价物为原料，合成了2,2-双(1h -吲哚-3-基)苊-1(2H)- 1。此外，利用2,2-二(2-甲基- 1h -吲哚-3-酰基)苊-1(2H)- 1的光致发光特性，在由H2O和CH3CN组成的混合溶剂体系中探测铜离子，激发波长为410 nm，检出限为9.5∙10-6 M。

The Synthesis of 2,2-BIS(1-INDOL-3-YL)Acenaphthylene-1(2)-Ones Using Nanocatalysis: Fluorescent Sensing for Cu2+ Ions

Abstract 2,2-bis(1H-indol-3-yl)acenaphthylene-1(2H)-ones were synthesised by the reaction of acenaphthenequinone and 2 equivalents of indole using Fe3O4@SiO2@Si-Pr-NH-CH2CH2NH2 as the basic magnetic nanocatalyst, assembled under greener and sustainable conditions in high purity and yields. Furthermore, the photoluminescence properties of 2,2-bis(2-methyl-1H-indol-3-yl)acenaphthylene-1(2H)-one were exploited for the sensing of copper ions in the mixed solvent systems comprising H2O and CH3CN in excitation wavelength at 410 nm with a detection limit of 9.5 ∙ 10–6 M.
