Growth of aromatic molecules on solid substrates for applications in organic electronics

摘要

The growth of molecular adlayers on solid substrates is reviewed with a special emphasis on molecules of relevance for organic electronics. In particular, we will consider planar molecules with extended pi-systems, namely acenes (anthracene, tetracene, pentacene), perylene, coronenes, diindenoperylene, 3,4,9,10-perylene-tetracarboxylicacid-dianhydride, poly-phenylenes, oligothiophenes, and phthalocyanines. Special consideration is given to the importance of the formation of ordered molecular overlayers, which are compared with the structure of the corresponding bulk crystals. Whenever possible, aspects relevant for device fabrication (morphology of deposited films, mobilities of charge carriers) will be addressed.
