摘要

Herein we show that cyclometalated, square planar Pt(II) complexes can be tuned to achieve deepblue phosphorescent emitters. For this purpose, the introduction of an electron-donating moiety on two different bidentate N boolean AND N and N boolean AND O fluorine-free luminophores, namely 2-(1H-tetrazol-5-yl) pyridine and picolinic acid, was carried out. The remaining two coordination sites of the Pt(II) metal center were filled by a sterically demanding cyclometallating unit, namely a tertiary phosphite C boolean AND P ligand. This ancillary ligand avoids aggregation and provides high solubility in organic solvents. Based on this approach, we were able to blue-shift the emission of the complexes down to 411 nm, and to achieve a maximal photoluminescence quantum yield of 56% in the solid state.
