However, anthracene derivatives, including the force-responsive ones, have previously only been studied in solution, films, or elastomers; leaving room open for their novel application in other material schemes, including engineering composites.

In both the CEWAF and WAF solutions, naphthalene was the predominant (65%-84%, CEWAF, WAF) PAH compound, but anthracene also made a significant contribution to the total PAH (16.
In addition, the environmental protection agency (EPA) has set up an index of air pollution that refers to sixteen PAHs including naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, dibenzo(a,h)anthracene, benzo(ghi)perylene, indeno(1,2,3-cd) pyrene, benzo(a)pyrene, etc.
