Bis(2‐methyl­quinolin‐8‐olato‐κ2N,O)(6‐phenyl‐2‐naphtholato‐κO)aluminium(III)

The five-coordinate geometry of the Al atom in the title compound, [Al(C10H8NO)2(C16H11O)], is trigonal–bipyramidal, in which the O-donor atoms of the naphtholate and the two quinolinolate ligands are in the trigonal equatorial plane and the N atoms in the axial positions.

P-144: Host Materials for Orange and Red Phosphorescent OLEDs

This paper discusses the parameters and related results considered for the development of host materials for red and orange phosphorescent OLEDs (e.g., triplet energy, thermodynamic properties, material purity, and device performance). Exceptional power efficiency characteristics for select hosts will also be discussed.

(2,6-Diphenyl­phenolato-κO)bis­(2-methyl­quinolin-8-olato-κ2N,O)gallium(III)

The title compound, [Ga(C10H8NO)2(C18H13O)], is a mononuclear five-coordinate Ga complex having a trigonal–bipyramidal geometry in which the O-donor atoms of the phenolate and of the two quinolinolate ligands form the trigonal equatorial plane, and the N atoms are in axial positions.

Bis(2,6-diphenyl­phenolato)(2-methylquinolin-8-olato)aluminium(III)

The title compound, [Al(C10H8NO)2(C18H13O)], is representative of the class of compounds commonly known as the blue aluminium chelates (BAlq) that are useful in organic electroluminescent devices. The geometry of this compound is approximately trigonal–bipyramidal, with the trigonal base formed by the O donor atoms of the phenolate and two quinolinolate ligands.
