Triaryl-Boron Functionalized Dinuclear Platinum Complexes Linked by Photoisomerizable Bpe Ligand: Luminescence and Isomerism
2017-10-12T14:24:05Z (GMT) by
We report herein a series of triarylboron-functionalized Pt(II) dinuclear complexes using a photoactive bis(4-pyridyl)ethylene (bpe) bridging unit. The new Pt(II) complexes display phosphorescence at both room temperature and 77 K. Depending on the conditions under which crystals of the complexes were grown, either the <i>cis</i>- or <i>trans</i>-isomers could be obtained. The <i>trans</i> and <i>cis</i> isomers were found to undergo light-induced isomerization in solution with the <i>trans</i> isomer being the dominant species.
