Polymorphism at the Metal/Organic Interface: Hybrid Phase with Alternating Coplanar and Vertical Adsorption Geometry

Polymorphism of organic molecular materials plays a prominent role in organic (opto)electronic devices, where the structural properties of metal/organic interfaces determine performance-critical parameters such as charge carrier injection rates. Here, we show that (sub)monolayers of a 2D-prochiral aromatic dinitrile with a bent quaterphenyl backbone engage in pronounced polymorphism on a Ag(111) surface and form a unique phase with alternating...
