Method for Synthesis of Tetrabenzoporphyrin Precursor for Use in Organic Electronic Devices

We developed a new synthetic method for bicyclo[2.2.2]­octadiene (BCOD)-fused porphyrin (<b>1</b>), a tetrabenzoporphyrin (TBP, <b>2</b>) 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 other existing methods, and thus, the new method can efficiently synthesize the TBP precursor
