Synthesis, structural characterization, and fluorescent chemosensory properties of novel molecular clips based on diethoxycarbonyl glycoluril

A New Fluorescent Sensor for Fe3+ Based on Glycoluril Molecular Clip

“…When Fe 3+ is added, clip 1 is binding with Fe 3+ , the fluorescence of clip 1 was markedly quenched. It can be inferred from the crystal structure that Fe 3+ may much easier to form coordinative interactions with ‐OH and the polarized C=O than other metal ions tested in this paper . The above titration experiment indicates that fluorescence quenching has to be associated to the metal complexation by the glycoluril C=O and ‐OH, in particular, the Fe 3+ is paramagnetic and the d shell is unfilled, which is responsible for the quenching of the charge transfer excited state of the 2,7‐dihydroxynaphthalene fragment of clip 1 .…”

A novel turn-on colorimetric and fluorescent sensor for Fe3+ and its application in living cells

“…In continuing of our study on developing molecular sensors for Fe 3+ detection [34,35], herein, we introduce a novel and simple method to prepare rhodamine B-based chemosensor by three steps reaction. The sensor 1 showed "off-on" type chromogenic behavior toward Fe 3+ over other metal ions.…”
