Abstract

An Indane-1-one derivative 11-(1-benzyl-1H-indol-3-yl)-10,12-dihydrodiindeno[1,2-b:2',1'-e]-pyridine (BDP) has been synthesized by the reaction of Indan-1-one with 1-benzyl-1H-indole-3-carbaldehyde. FT-IR, ¹H-NMR, ¹³N-NMR and Mass spectroscopic techniques has been used to confirmed the structure of BDP. The observed photophysical changes in BDP across various solvents were associated. The impact of various interactions on photophysical parameters, including Stokes shift, dipole moment, oscillator strength, and fluorescence quantum yields, has been assessed in relation to solvent polarity. Moreover, BDP demonstrates potential as a selective fluorescent chemosensor for detecting Fe³⁺ ion within a range of cations in an aqueous DMSO environment. A thorough investigation into the recognition mechanism of BDP towards Fe³⁺ ion has been conducted using Benesi-Hildebrand and Stern-Volmer, measurements. BDP forms a 2:1 complex with the Fe³⁺ ion, exhibiting fluorescent quenching behaviour.

一锅合成的新型茚芴衍生物 (BDP) 作为检测 Fe3+ 离子的荧光化学传感器的光物理研究。

一种茚-1-酮衍生物 11-(1-苄基-1H-吲哚-3-基)-10,12-二氢二茚并[1,2-b:2',1'-e]-吡啶（BDP）是由茚-1-酮与 1-苄基-1H-吲哚-3-甲醛反应合成的。利用 FT-IR、1H-NMR、13N-NMR 和质谱技术确认了 BDP 的结构。观察到的 BDP 在不同溶剂中的光物理变化与此相关。评估了各种相互作用对光物理参数（包括斯托克斯位移、偶极矩、振荡器强度和荧光量子产率）的影响与溶剂极性的关系。此外，BDP 显示出作为一种选择性荧光化学传感器的潜力，可在 DMSO 水环境中检测一系列阳离子中的 Fe3+ 离子。我们利用 Benesi-Hildebrand 和 Stern-Volmer 测量方法对 BDP 与 Fe3+ 离子的识别机制进行了深入研究。BDP 与 Fe3+ 离子形成 2:1 的复合物，表现出荧光淬灭行为。

期刊介绍： Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
