Description

technical field

[0001] The present invention relates to a synthesis method of bispyrrole-fused borazanthane and its derivatives. The commercially available 1,5-difluoro-2,4-dinitrobenzene is used as a raw material, through the nucleophilic substitution of pyrrole reaction, reduction, and Lewis base-directed electrophilic borocyclization to give a series of bispyrrole-fused borazanthene compounds. The synthesis method is simple and easy to operate, has mild reaction conditions, fast reaction rate and high yield, and the compound has potential application value in the field of organic photoelectric materials. Background technique

[0002] Polycyclic aromatic hydrocarbons are rich in carbon atoms, have large conjugated systems and outstanding electronic properties, and have received more and more attention in new organic optoelectronic materials, such as organic light-emitting diodes, organic semiconductor materials, solar cells (OPVs) and Field effect transistors (OFETs) have...
