A novel pentalene-centered polycyclic 24π-electron system, IB1, was synthesized via a Pd-catalyzed homocoupling reaction. The geometry structure was studied by X-ray diffraction and theoretical method. The HOMO level of IB1 was studied by electrochemical experiment and DFT methods. The IB1 molecule shows a strong electro-donating property and can form a charge transfer complex with electro-acceptor TCNQ, indicating fascinating potential in the field of organic electronics.
