Abstract
A new two-dimensional (2D) lanthanide metal–organic framework [Eu2(ATA)3(phen)2]n (Eu-MOF, H2ATA = 2-amino terephthalic acid, phen = 1,10-phenanthroline) was successfully self-assembled via a simple solvothermal method. Then D-camphoric acid (D-Cam) was grafted onto Eu-MOF by post-synthetic modification (PSM) through a mechanochemical approach, successfully fabricating the chiral material Eu-MOF-D-Cam. Remarkably, this modification not only significantly enhanced the luminescent properties but also introduced the chiral sites for enantioselective sensing of mandelic acid (MA) enantiomers. The enantioselectivity factor α (α = KSV(R-MA)/KSV(S-MA)) of Eu-MOF-D-Cam was 2.56. These findings establish Eu-MOF-D-Cam as a promising photoluminescent sensor for chiral discrimination of R/S-MA enantiomers.
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.
