Fusedporphycenes have attracted growing interest in recent years. However, the molecules generated to date suffer from different drawbacks such as multistep syntheses, low yields, and the lack of a convenient synthetic strategy. Here, we present our latest results concerning the synthesis of a suitable platform for the generation of large fusedporphycenes.
We developed a new synthetic method for bicyclo[2.2.2]octadiene (BCOD)-fused porphyrin (1), a tetrabenzoporphyrin (TBP, 2) precursor that is well-known as a good material for use in organic electronic devices. The newly developed method synthesizes the BCOD-fused pyrrole intermediate (which is the most important intermediate in synthesizing BCOD-fused porphyrin) in a simpler and easier manner than
