Near-IR dyes that absorb and emit in the red visible or near-IR region
have attracted great interest in the fields of medicinal chemistry and
biochemistry for the last few decades. This interest is due to the multiple
notes of metal ions in biological and enviromental processes. Therefore the
development of cation selective and sensitive sensors have been a hot
subject for many researchers. Consequently, fluorescence based sensors
are the most efficient and favorable ones among its counterparts in the field
of sensor research.
In this study, we have targeted to synthesize BODIPY based near-IR
dyes as a selective fluorophore for Zn (II) and Hg (II) cations. We have also
demonstrated that the versatile BODIPY fluorophore can be functionalized for
long wavelength emission on the 3 and 5 position of the BODIPY core with
multiple and distinct functional groups in a stepwise manner. Thus we are
able to link two BODIPY cores with a different absorption wavelengths to
each other first time with click chemistry strategy to generate a chemosensor
for Hg (II) cation.
