The title of the article was 《A Discrete Platinum(II) Metallacycle Harvesting Triplet Excitons for Solution-Processed Deep-Red Organic Light-Emitting Diodes》.Safety of 4-Ethynylpyridine The author mentioned the following in the article:
Platinum(II) coordination-driven architectures have exhibited unique features in fabricating functional supramol. materials. By introducing luminescent moieties into the ligand structure, various light-emitting metallacycles and metallacages have been facilely prepared, presenting specific applications in chem. sensing, light-harvesting, and bio-imaging. Except for building up the metal-ligand bonds, the platinum(II) center should also benefit the ultimate luminescence due to its unique photophys. traits. Here, a platinum(II) metallacycle with deep-red emission for solution-processed organic light-emitting diodes is reported. This metallacycle is assembled by mixing a 180° di-Pt(II) acceptor with a pyridyl-decorated ligand functionalized by a deep-red fluorescent emitter. Notably, the platinum(II) acceptor permits the efficient intramol. transfer of all elec. generated singlet and triplet excitons from itself to the fluorescent moiety, which dramatically enhances the external quantum efficiency of the device compared with the one consisting of the sole ligand. The present results reveal the function of platinum(II) metallacycles in light-emitting devices, a finding which should apply to other coordination-driven architectures with versatile properties.

4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. Safety of 4-Ethynylpyridine
