Red electroluminescence from transparent PVK-dye films based on dipyrido[3,2-a:2′,3′-c]phenazine and Re(CO)3Cl-dipyrido[3,2-a:2′,3′-c]phenazine dyes

Synthesis and Characterization of a Multicomponent Rhenium(I) Complex for Application as an OLED Dopant

“…[b] dppz À1600 [26] n.d. À6.22 [27] À2.96 [27] [25] Angewandte Chemie those of dppz, 2, or 3, and thus 5 and 6 are expected to be better hole-transporting materials. The electrochemical data show that 6 has the smallest band gap energy of the compounds studied, and the relative energies of its HOMO and LUMO suggest that it favors transport of both holes and electrons.…”

Synthesis, structure and luminescent properties of rhenium(I) carbonyl complexes containing pyrimidine-functionalized N-heterocyclic carbenes

“…In general, two approaches have been used in tuning the properties of the diimine ligands. One focuses on diimne ligands with different ligand strengths [29,30] to adjust the molecular orbital energy levels in the Re(I) complexes.…”

Synthesis, photophysical properties, and theoretical studies on pyrrole-containing bromo Re(I) complex

“…Since the first report on the electroluminescence (EL) of the Re(I) complexes [1], several groups paid attention to explore novel Re(I) complexes [2][3][4][5][6] with the potential application in EL devices because of these materials' potentiality of achieving an internal quantum efficiency of 100% with the application of triplet irradiative emission. However, the commercial basic materials from which the widely studied chloro Re(I) complexes are synthesized are very expensive, which limits the practical application of this kind of Re(I) complexes.…”
