Sensitive Detection and Visual Recognition of Emodin Based on a Zn Coordination Polymer Probe
Based on 2,4,6-pyridinetricarboxylic acid (H3ptba) and o-phenanthroline (phen), a zinc-based fluorescence coordination polymer was successfully synthesized, namely, [Zn3(ptba)2(phen)2(H2O)4]n (1). The single-crystal diffraction analysis shows that Zn2+ ions in complex 1 are alternately connected with ptba3− and phen ligands to form a one-dimensional chain structure, which further constitutes a three-dimensional supramolecular architecture through the π···π interactions. Complex 1 demonstrated excellent stability of thermogravimetry and displayed good fluorescence intensity in aqueous solution with a wide pH range. In this work, complex 1 was used as a fluorescence sensor for the detection of the emodin (Emo) molecule. It was found that complex 1 had high sensitivity with the detection limit of 1.0 × 10−7 M and simultaneously displayed specific selectivity for the exploration of the Emo molecule. The dynamic quenching, the absorption competition, and the photo-induced electron transfer process are responsible for the recognition mechanism of complex 1 with sensing Emo. It is worth mentioning that a fluorescent film based on complex 1 was successfully fabricated, which could rapidly recognize the Emo molecule with the naked eye further.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
