Many luminescent platinum(ii) complexes undergo face-to-face interactions between neighbouring molecules, leading to bimolecular excited states that may emit at lower energy (dimers and/or excimers). Detailed photophysical studies are reported on din... Read More about Rigidly linked dinuclear platinum( ii ) complexes showing intense, excimer-like, near-infrared luminescence.
