Anthracene is a polycyclic aromatic hydrocarbon (C14H10) with D2h symmetry; here, we're looking at all molecules with the anthracene substructure of three fused rings. Anthracenes are formed withand have been structurally characterized with -variable substitution patterns and electronic modifications. The related anthraquinones (anthracene-9,10-dione) are commonly used as dyes in nature and industry.
