Synthesis and Solution Behavior Studies of a Bifunctional Fluorenyl Dioxotetraamine and Its Copper(II) Complex

The fluorenyl dioxotetraamine L4 was designed and prepared. The solution behavior of L4 and its interaction with the CuII ion were studied by pH potentiometric, fluorimetric and spectrophotometric titration. In the dioxane/water solution, it was found that the molecule L4 showed an “off‐on” or “on‐off” fluorescent response in the absence or presence of the CuII ion with the increase of the pH value. Moreover, influenced by the CuII ion, the fluorescence of the dioxotetraamine L4 can be almost quenched when the pH value was slightly higher than 4.0, which is rarely reported and useful to detect the CuII ion under acidic condition.
