A series of 9-(fluoren-2-yl)anthracene derivatives bearing either thiophene (FATh), triphenylamine (FAT and FATT) or pyrene (FATP) moieties as substituents have been designed, synthesized, and characterized as non-doped blue emitters for organic light-emitting diodes (OLEDs). Their optical, electrochemical and thermal properties have been investigated, and their molecular structure-property relationships were evaluated. All FAT, FATT and FATP compounds possess combined blue-light-emitting and hole-transporting characteristics, and showed stable amorphous states with high fluorescence quantum yields in solution (up to 89 %) and strong luminance in the OLED devices, whereas FATh showed poor photoluminescent and electroluminescent properties. Efficient, non-doped blue and Alq3-based green OLEDs were fabricated and characterized. The blue and green devices with maximum luminance efficiencies and CIE coordinates of 3.17 cd A-1 and (0.13, 0.14), and 3.81 cd A-1 and (0.28, 0.50) were achieved, respectively, with FATT having 4-{bis[4′-(diphenylamino)biphenyl-4-yl]amino}phenyl substituents as emitting layer and hole-transporting layer, respectively. These devices also showed considerably low turn-on voltages of 3.0 and 2.6 V, respectively. New 9-(fluoren-2-yl)anthracene derivatives with combined blue-light-emitting and hole-transporting characteristics have been developed that exist in a stable amorphous state and deliver high fluorescence quantum yields.

New 9,10-substituted anthracene derivatives were designed and synthesized for application as blue-emitting and hole-transporting materials in electroluminescent devices. They were characterized by H NMR, C NMR, FTIR, UV-vis, PL spectroscopy, and mass spectrometry. The theoretical calculation of three-dimensional structure and the energy densities of HOMO and LUMO states, as well as optical properties of these new obtained materials, supported the claim that they had non-coplanar structures. Their optical, thermal, and electrochemical properties could be tuned by varying the peripheral substituents. All of them were electrochemically and thermally stable molecules. Materials having electron donating triphenylamine as peripheral substituents showed promising potential as both blue light-emitting materials and hole-transporting materials for electroluminescent devices. Efficient blue and Alq3-based green OLEDs with maximum luminance efficiencies and CIE coordinates of 1.65 cd/A and (0.15, 0.16) and 6.25 cd/A and (0.26, 0.49) were achieved, respectively.
