Two pyrazolate-bridged based binuclear platinum complexes are prepared.
- class="label">•
Both platinum complexes show a dual emission at 480 and 690 nm in solution and thin film.
- class="label">•
NIR emission peak at 692 nm with a shoulder at 753 nm is observed in the platinum complexes-doped PLEDs.
