  Impact of a Picolinate Ancillary Ligand on Phosphorescence and Fluoride Sensing Properties of BMes₂-Functionalized Platinum(II) Compounds

  摘要：

  Two new dimesitylboron (BMes(2))-functionalized 2-phenylpyridine cyclometalated Pt(II) complexes (2 and 3) with a picolinate or a methyl-picolinate as the ancillary ligand have been synthesized via a one-pot procedure at ambient conditions with high yields (>70%). The crystal structures of these Pt(II) complexes were determined by single-crystal X-ray diffraction analysis, which revealed the presence of extended pi-stacking interactions in the crystal lattice of 2 and discrete dimer formation in the lattice of 3. Both complexes exhibit dual phosphorescence emission in solution at room temperature under N-2 atmosphere. These unusual photophysical properties have been systematically investigated by spectroscopic and computational studies, which established that the phosphorescent dual emission originates from admixture of (LLCT)-L-3 and (ILCT)-I-3/(MLCT)-M-3 transitions. Fluoride titration experiments were conducted to further confirm the origin of phosphorescence in these compounds. The phosphorescent properties and the phosphorescent response toward fluoride ions by compounds 2 and 3 are distinctly different from the previously known BMes(2)-functionalized (NC)-C-boolean AND-chelate Pt(II) compounds, which are attributed to the introduction of the low-lying pi* orbital by the picolinate ancillary ligand in the Pt(II) compounds.

  Tri-(2-picolyl)amine-modificated triarylborane: Synthesis, photophysical properties and distinguish for cyanide and fluoride anions in aqueous solution

  摘要：

  We designed and synthesized a tri-(2-picolyl) amine (TPA) functionalized triarylborane, 1-(6-(4-(dimesitylboryl)phenyl)pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)methanamine (PB2). The photophysical properties of PB2 were thoroughly explored. Moreover, PB2 can capture CN- and F- in aqueous solution through strong chelation induced by the synergy of a boron atom andmetal ion gripped by TPA to display entirely different fluorogenic responses such as fluorescence enhancement for CN- and fluorescence quenching for F-. The results of TOF-MS-EI analysis and theoretical calculations indicate that the complexing of PB2 with CN- formed a 2-to-2 adduct with a stabilized configuration, resulting in strong emission. The complexing of PB2 with F- formed a 1-to-1 adduct with a loose configuration, resulting in weak emission. In pure water, the detection limit of PB2 for CN- is 0.79 mu M, and in H2O/THF (1:9 v/v) system, the detection limits of PB2 for CN- and F- can reach 0.39 and 2.12 mu M, respectively, indicating its potential application for effective detection and discrimination of CN- and F-.
