Abstract: In this study, we synthesized a new fluorescent polypyridyl dye 2 containing a 2,2\'-bipyridine in the center and
two 2,2\':6\',2\'\'-terpyridines at both ends. When exposed to various metal ions, the dye 2 showed selective fluorescence
responses. In the presence of Cu2+ and Ni2+, it exhibited a highly effective fluorescence quenching, leading to large Ksv values
of up to 105. In response to most other metal ions including Al3+, in contrast, its fluorescence changes little, showing a small
Ksv value at 102. Meanwhile, the compound 2 revealed a differentiated fluorescence response to Zn2+, which is evidenced by
a large red shift of > 100 nm. Such a red shift from the ion binding is attributed to the planarization of the bipyridyl unit
extending the effective conjugation length in conjunction. A polypyridyl compound will find important usefulness in
chemosensor application due to its selective binding to metal ions. Subsequent research concerned with modified derivatives
is currently going on, as a way to provide high solubility even after metal-complexing. |
