| Abstract: | The raw material dibenzothiophene-4-boric acid which was coupled with o-bromoiodobenzene and reacted with Ph2PCl after lithiation,then the title products 5-phenyl-5H-benzo[2,3]phosphindolo[4,5-b]benzothiophene(5 and 6)were got after the Pd(OAc)2-catalyzed cyclization.The structures were characterized by 1H NMR,13C NMR and HR-MS(ESI).Acording to the results of UV-Vis,fluorescence and TGA spectra,5 and 6 have great emissive ability,and the maxima fluorescence emission is around 390 nm.Their thermal decomposition temperatures are above 270℃,which illuminates the potential application in the field of organic electroluminescent materials. |
