摘要
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 7 r-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-（9 H-carbazol-9-yl）phenyl）pyridine（1 %） as an emitter present a maximum brightness of 632 cd/m^2 at 14.7 V with the CIE coordinate of（0.623,0.349）.
