Multicomponent, one-pot, highly efficient, indium trifluoride (InF3) catalytic synthesis of 2-(naphthalen-1-yl)-4,5-diphenyl-1H-imidazole under solvent-free condition is reported. Characterization of imidazole has been carried out by spectral techniques. The synthesized phosphated imidazole (PI) and phosphated imidazole bound magnetic nanoparticles (PIBMN) were characterized using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and powder X-ray diffraction (XRD). The photophysical characteristics of the synthesized phosphated imidazole and phosphated imidazole bound magnetic nanoparticles were investigated by steady-state absorption and emission spectroscopy as well as time resolved fluorometry. From these experiments, the position of the spectral maxima (λabs, λexc and λemi), and lifetime (τ) of the synthesized phosphated imidazole and phosphated imidazole bound magnetic nanoparticle have been determined.
报道了在无溶剂条件下，多组分、一锅法、高效的三氟化铟（InF3）催化合成2-(萘-1-基)-4,5-二苯基-1H-咪唑。已通过光谱技术对咪唑进行了表征。使用傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、能量色散X射线光谱（EDS）和粉末X射线衍射（XRD）对合成的磷酸化咪唑（PI）和磷酸化咪唑负载磁性纳米颗粒（PIBMN）进行了表征。通过稳态吸收和发射光谱以及时间分辨荧光法研究了合成的磷酸化咪唑和磷酸化咪唑负载磁性纳米颗粒的光物理特性。通过这些实验，确定了合成的磷酸化咪唑和磷酸化咪唑负载磁性纳米颗粒的光谱最大值位置（λabs、λexc和λemi）以及寿命（τ）。
