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.

基于环戊四烯的电子受体
已通过钯催化的环戊环化反应制备了基于并四苯的新型环戊基稠合多环芳烃 (CP-PAHs)。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。光氧化稳定性介于之前制备的基于蒽和并五苯的 CP-PAHs 之间，如传统并苯稳定性中所见。侧芳基的 Scholl 环化脱氢导致材料快速形成内过氧化物产物。
