“…Density Functional Theory (DFT) that was revealed in accordance with this goal uses the electron density to identify the reactivity or stability [11][12][13][14][15][16][17]. It should be noted that hybrid functionals such as B3LYP and M062 are widely preferred in the studies regarding the explanation of reactivity properties of molecules [18][19][20][21][22][23][24]. Additionally, in the studies also researching organic light emitting diode performances of various molecules, the aforementioned functionals have been used [25][26][27][28][29][30][31].…”

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 4,4ꞌ-azopyridine [AZPY], 4,4ꞌ-bipyridine [BIPY], 1,2-bis[4ꞌ-(4-methylphenyl)2,2ꞌ:6ꞌ2ꞌꞌ-terpyridin-6-yl]ethyne (BISTERPY), 5,5ꞌ-diamino-2,2ꞌ-bipyridine (DABP), dipyrido[3,2-a:2ꞌ,3ꞌ-c]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. 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.
