Contorted Heteroannulated Tetraareno[a,d,j,m]coronenes [Data]
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Cata-condensed heteroannulated tetraarenocoronenes with C2h symmetry have been obtained from three doubly brominated diarenoperylenes. X-ray diffraction showed that the coronenes mostly adopt S-shaped contorted π-planes. The large variety of fused rings in the coronenes′ core allows good control of their photophysical properties and thus their potential use in organic electronics applications' .
