The bisferrocene-benzobisimidazole triad behaves as a selective redox and fluorescent chemosensor for HSO(4)(-) and Hg(2+) ions, exhibiting an easily detectable signal change in both the redox potential of the ferrocene/ferrocinium redox couple and in the emission band which is red-shifted (Δλ = 10-13 nm) and enhanced in intensity (Chelation Enhanced Fluorescence, CHEF = 486-225) upon complexation with these ions, in EtOH solutions.
双二茂铁苯并咪唑三联体可作为一种对 HSO(4)(-)和 Hg(2+)离子具有选择性的氧化还原和荧光化学传感器，在与这些离子络合时，在乙醇溶液中，其铁/亚铁氧化还原电对的氧化还原电位和发射带都发生了易于检测的信号变化（Δλ = 10-13nm），强度增强（螯合增强荧光 CHEF = 486-225）。
