从红色到近红外 OLED：在一个环金属化 [Pt(N^C^N)X] 配合物中，X 从 -Cl 变为 -NCS 所产生的显著影响{ N^C^N = 5- 均三甲苯基-1,3-二-(2-吡啶基)苯}。
From red to near infra-red OLEDs: the remarkable effect of changing from X = -Cl to -NCS in a cyclometallated [Pt(N^C^N)X] complex {N^C^N = 5-mesityl-1,3-di-(2-pyridyl)benzene}.

Abstract
[PtL(6)X] {X = Cl or NCS and L(6) = 5-mesityl-1,3-di(2-pyridyl)-benzene} display similar luminescence in solution but, in the solid state, the packing of the molecules is different, with short PtPt interactions for X = NCS, leading to a red-shifted emission band. The effect has been used to generate OLEDs that emit squarely in the NIR region (855 nm).
摘要
[PtL(6)X] {X = Cl 或 NCS，L(6) = 5-均三甲苯基-1,3-二(2-吡啶基)苯} 在溶液中显示出相似的发光，但在固态中，分子的堆积方式不同，对于 X = NCS，PtPt 相互作用较短，导致发射带红移。该效应已被用于生成发射位置刚好在近红外区域 (855nm) 的 OLED。
