| Multi-substituted imidazoles possess an important excited-state intramolecular proton transfer property. They play critical roles in applications to electroluminescent components and fluorescence labeling agents. They also have a wide range of biological properties namely anti-fungal, anti-bacterial, and anti-inflammatory activities. In view of their enormous applications, a simple, efficient, and environment friendly synthetic method was adopted for the synthesis of a series of 1-(4,5-diaryl-1H-imidazol-2-yl)naphthalen-2-ols and 1-(1-(4-methoxyphenyl)-4,5-diaryl-1 H-imidazol-2-yl)naphthalen-2-ols with various functional groups via condensation, oxidation, and cyclization reactions. All the synthesized imidazoles were characterized by 1H NMR, 13C NMR, and elemental analysis. Their photophysical properties have been studied by UV-Vis and fluorescence spectroscopy in dichloromethane, methanol, N,N-dimethyl formamide, and dimethyl sulfoxide, respectively. |
