以并四苯为原料，通过钯催化的环戊环化反应合成了新型的环戊稠合多环芳烃（CP-PAH）。新化合物具有低能量的最低未占分子轨道（LUMO）和相对较小的带隙。的光氧化稳定性的中间先前制备的CP-PAH的蒽和并五苯的基础上发现在传统的并苯稳定性。侧芳基的Scholl环化脱氢导致快速形成内过氧化物产物的材料。
New cyclopenta-fused polycyclic aromatic hydrocarbons (CP-PAHs) based on tetracene have been prepared by a palladium-catalyzed cyclopentannulation reaction. The new compounds have low-energy lowest unoccupied molecular orbitals (LUMOs) and relatively small band gaps. The photooxidative stability was intermediate to previously prepared CP-PAHs based on anthracene and pentacene as found in traditional acene stabilities. Scholl cyclodehydrogenation of pendant aryl groups led to materials that quickly formed endoperoxide products.
