吲哚烷-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',通过茚满-1-酮与1-苄基-1H-吲哚-3-甲醛的反应合成了1'-e]-吡啶(BDP)。FT-IR,1H-NMR,13N-NMR和质谱技术已用于证实BDP的结构。在各种溶剂中观察到的BDP的光物理变化是相关的。各种相互作用对光物理参数的影响,包括斯托克斯移位,偶极矩,振荡器强度,和荧光量子产率,已经评估了与溶剂极性的关系。此外,BDP显示出作为选择性荧光化学传感器的潜力,可在DMSO水溶液环境中检测一系列阳离子中的Fe3离子。使用Benesi-Hildebrand和Stern-Volmer对BDP对Fe3离子的识别机制进行了彻底的研究,测量。BDP与Fe3+离子形成2:1络合物,表现出荧光猝灭行为。
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.
