Six novel disubstituted phenylene‐linked bis‐imidazole derivatives, 3a–3f, were prepared by a one‐pot, microwave‐assisted method under solvent‐free conditions, in yields ranging from 61.6 to 85.6%. The new compounds were characterized by 1H‐ and 13C‐NMR, UV/VIS, and fluorescence spectroscopy, and mass spectrometry, as well as by elemental analyses. The influence of substituents and solvents on the
