An anthracene-based fluorescence (FL) system was synthesized via a general synthetic procedure. Fourier transform infrared spectroscopy (FTIR), MALDI-MS, and nuclear magnetic resonance spectroscopy (C and H NMR) were carried out to characterize the multi-anthracene containing probe. The photophysical properties of the probe were illustrated via 3D-FL analysis and excitation-emission matrix (EEM) measurements. Density-functional theory (DFT) was applied to optimize the structure of the prepared probe and investigate its molecular interactions with Fe. The FL proficiency of the probe was appraised by spectroscopic measurements like Ultraviolet-Visible (UV-Vis) and FL spectroscopies. The simple and highly sensitive probe was able to diagnose ferric ions' low concentrations and detection limit reached upto 0.223 µM with linear working range between 0.22 and 92.00 µM for Fe ions. The efficacy of this fluorescent probe was confirmed by testing for iron determination in environmental samples. Various fluorophores or ionophores could be applied for achieving novel probes by the proposed procedures and for diagnosing diverse metal ions.
通过一般的合成方法合成了一种基于蒽的荧光（FL）体系。采用傅里叶变换红外光谱（FTIR）、基质辅助激光解吸电离质谱（MALDI-MS）和核磁共振谱（C 和 H NMR）对多蒽探针进行了表征。通过三维荧光（3D-FL）分析和激发发射矩阵（EEM）测量说明了探针的光物理性质。应用密度泛函理论（DFT）对制备探针的结构进行了优化，并研究了其与 Fe 的分子相互作用。通过紫外可见（UV-Vis）和荧光光谱等光谱测量评估了探针的荧光性能。该简单且高灵敏度的探针能够诊断出低浓度的铁离子，检测限可达 0.223µM，Fe 离子的线性工作范围在 0.22 和 92.00µM 之间。通过在环境样品中进行铁测定来验证该荧光探针的功效。通过所提出的程序，可以应用各种荧光团或离子载体来获得新型探针，并用于诊断各种金属离子。
