-
5-Phenyl-5H-benzo[2, 3]phosphindolo[4, 5-b]benzofuran 4 and 5 were synthesized by dibenzofuran-4-boronic acid as starting material. After Suzuki coupling reaction, lithiation by n-butyllithium and Pd(OAc)2 catalyzed cyclization, the titled compounds were obtained, and their structure were characterized by NMR and HRMS. Their physical-chemical properties were studied using UV, fluorescence spectra and TGA. The results showed that this kind of compounds have potential application in the field of organic electroluminescent materials.
