| Abstract: | A novel dimesityl-decorated bistetracene derivative 8,16-dimesityltetraceno[2,1,12,11-opqra]tetracene (DMTA) has been synthesized and characterized. Its single crystal analysis demonstrates that the parent bistetracene backbone is almost in a plane without any intermolecular π-stacking interaction. DMTA exhibited the low-energy absorption at 560/607 nm and emission spectra at 617/663 nm, respectively. The fabricated device based on DMTA doping into 2,6-bis(3-(9H-carbazol-9-yl)phenyl)pyridine (1%) as an emitter present a maximum brightness of 632 cd/m2 at 14.7 V with the CIE coordinate of (0.623, 0.349). |
