Mixed Oligomers Based on Phospholes with Other Hetero aromatics

Mixed Oligomers Based on Phospholes with Other (Hetero)aromatics 

One key property of pyridylphosphole ligands is their heteroditopic nature. They possess two coordination centers with different stereo-electronic properties, which, in accordance with Pearson s antisymbiotic effect [42a], can control the orientation of a second chelating ligand in the coordination sphere of a square-planar d8-metal center [42b]. This property has been exploited in order to control the in-plane parallel arrangement of ID-dipolar chromophores [42d]. Phospholes
