TI  - Theoretical analysis of OLED performances of some aromatic nitrogen-containing ligands
AB  - It is well-known that tris(8-hydroxyquinoline) aluminum (Alq3) complex and N,N’diphenyl-N,N’-bis(3-methylphenyl)-1,1’- diphenyl-4,4’-diamine compound (TPD) are widely used as electron transfer material (ETL) and hole transfer material (HTL) in organic light emitting diode (OLED) structure, respectively. Considering the reference materials, in the present work, the OLED performances of some cyclic aromatic structures such as 4,4 ꞌazopyridine [AZPY], 4,4 ꞌ-bipyridine [BIPY], 1,2-bis[4ꞌ-(4-methylphenyl)2,2ꞌ:6ꞌ2ꞌ ꞌ-terpyridin6-yl]ethyne (BISTERPY), 5,5ꞌ-diamino-2,2ꞌ-bipyridine (DABP), dipyrido[3,2-a:2ꞌ,3ꞌc]phenazine (DPP), 4,7-phenanthroline (PHEN) including nitrogen atom have been theoretically analyzed. It is important to note that B3LYP/6-31G(d) and B3LYP/TZP levels of the theory were taken into account for the calculations about monomeric and dimeric structures, respectively. Additionally, the calculations of the mentioned monomeric form were performed at B3LYP-D3/6-31G, CAM-B3LYP/6-31G and ωB97X-D/6-31G(d) levels. For a detailed theoretical analysis, the reorganization energies (λe and λh), adiabatic and vertical ionization potentials and electron affinities, the effective transfer integrals (Ve and Vh), and the charge transfer rates (We and Wh) of all compounds were computed by means of computational chemistry tools. In the light of calculated parameters, it is determined that these mentioned aromatic cyclic structures will be used in which layers of OLED structure. The results obtained in this study will be helpful in the design and applications of new molecules as OLED materials in the future.
