Cyclopent[fg]acepyrylene, cyclopent[jk]acepyryiene and cyclopent[mn]acepyrylene: novel C20H10 cyclopenta-fused polycyclic aromatic hydrocarbons

Abstract

Flash vacuum thermolysis of 1, 8-(2a), 1,6-(2b) and 1,3-bis(1-chloroethenyl)pyrene (2c) gives the novel C₂₀H₁₀ cyclopenta-fused Polycyclic Aromatic Hydrocarbons (CP-PAHs) cyclopent[fg]-(1a), cyclopent[jk]-(1b) and cyclopent[mn]acepyrylene (1c), respectively; bis(cyclopenta-fusion) topology has a profound influence on their properties.
