Fig. 2 The photophysical properties of the prepared benzofuroindoles. (A) Excitation and emission spectra of 4a, 4q, and 4s. (B) The CIE spectrum
of compound 4a. (C) The CIE coordinates of the obtained compounds.
perties of these cycloadducts suggest their potential for
efficient deep-blue OLED applications. Further efforts to apply
these products as electron donor moieties for TADF materials
and to evaluate their respective electroluminescence perform-
ance are currently underway.
