Short Abstract: 

Synthetic organic materials have gained an irrevocable presence in our daily lives. The variety of their applications is continuously growing, including highly refined functionalities as for example in optoelectronic devices, catalysts, filters or batteries. Regarding their synthesis, on-surface chemistry is rapidly attracting increasing attention. On the one hand it is expected to allow the synthesis of materials not achievable by conventional chemistry. On the other hand it overcomes potential problems in the transfer of complex molecular compounds synthesized by wet-chemistry onto solid device structures. In addition, running the reactions under ultra-high vacuum and on well-defined surfaces allows the use of a variety of sophisticated surface-science techniques for their characterization, which in turn may provide important insight into the reaction mechanisms,1,2,3 as well as into the product’s detailed properties.4-8 We have followed an on-surface chemistry approach for the synthesis and characterization of a variety of functional organic materials, including conjugated conductive polymers,4,5 atomically precise graphene nanoribbons of different kinds,6,7 and their associated heterojunctions.8
