By linking together two cyclometallated, N⁁C⁁N-coordinated platinum(II) complexes through a xanthene core, intense luminescence in the red region of the spectrum is achieved in solution at room temperature (λmax = 690 nm, Φlum = 0.20, τ = 1.7 μs in CH2Cl2) due to the efficient formation of an intramolecular excimer.
通过将两个环金属化的、N⁁C⁁N配位的铂(II)配合物通过一个蒽醌核心连接在一起,实现了在室温下溶液中在红色区域的强荧光发射(λmax = 690 nm,Φlum = 0.20,τ = 1.7 μs,在CH2Cl2中),这归因于高效形成的分子内激发态二聚体。
