Abstract:
Here, we report the synthesis of a novel class of B–N Lewis pair (LPB/N)-doped large acene derivatives (1a–1d) from the well-designed phenanthridine-based precursors. The resultant LPB/N-doped benzo-tetracene (1a), dibenzo-heptacene (1b), dibenzo-octacene (1c), and V-shaped tribenzo-nonacene (1d) are thoroughly characterized by X-ray crystallography, cyclic voltammetry, UV–vis absorption, and fluorescence spectroscopies together with DFT calculations. As a proof of concept, a 1a-based organic light-emitting diode device is fabricated to demonstrate the promising application in organic optoelectronics.
