Modulation of the Emission Mode of a Pt(II) Complex via Intermolecular Interactions
Compounds with controllable
color emissions are potentially useful as photoluminescent materials
in imaging and sensing applications. Multimolecular emission can be
used realizing variable-color emitters and has been demonstrated in
the solid state. However, achieving multimolecular emission in solution
is difficult to control. In this study, we used a combination of intermolecular
interactions, namely hydrogen bonding and solvophobic effect, to modulate
multimolecular emissions. A designed Pt complex demonstrated three
emission colors: blue (monomer emission), yellow (emission form hydrogen-bonded
dimer), and orange (aggregate emission). All of the emission modes
exhibited high luminescence quantum yields, as a result of their uniform
assemblies
