Diels–Alder reaction of 1,3-diarylbenzo[c]furan/cyclopentadienone with TTF followed by triflic acid mediated cleavage of the resulting adducts led to the formation of the respective 1,4-diaryl substituted naphthalenes, fluoranthenes, and fluorenones. The photophysical properties of representative diaryl-substituted hydrocarbons are also reported.

symmetrical/unsymmetrical benzo[c]furans with acenaphthylene in xylenes at reflux temperatures followed by p-toluenesulfonic acid-mediated epoxide cleavage and dehydration furnished diaryl/heteroaryl-substituted benzo[k]fluoranthenes. This strategy could be successfully applied to the synthesis of dimeric and trimeric benzo[k]fluoranthenes. Functionalization of representative benzo[k]fluoranthene derivatives
