A compound of Formula I M is selected from Pd or Pt; X is selected from N or CR3; each R1 and R2, which can be the same or different, and R3, are independently selected from the group consisting of hydrogen, deuterium, halogen, alkoxide, alkyl, cycloalkyl, heteroalkyl, heterocycle, cycloalkene, aryl, heteroaryl, and combinations thereof; wherein at least one of R1, R2, or R3 is selected from the group consisting of: a partially or fully fluorinated alkyl; a partially or fully fluorinated cycloalkyl; and a group of formula A connected to a carbon of one of Y1 to Y4 formula A, wherein Y1, Y2, Y3, and Y4 are independently selected from C or N, and no more than two of Y1 to Y4 is N; and Z is selected from the group consisting of O, S, NR5, and CR6R7. An OLED that includes an organic layer positioned between two electrodes, the organic layer including a compound of Formula I is also described. A consumer product that includes the OLED, and a formulation that includes a compound of Formula I, is also described.

, p. 778 - 783 (2007/10/03)
Previously unknown dysprosium(III), europium(III), and neodymium(III) complexes with tetraazaporphine were synthesized from the ligand and the corresponding metal acetylacetonates. The kinetic stability of the complexes in aqueous and methanolic solutions of acetic acid was studied. It was shown that the complexes in these media undergo solvoprotolytic dissociation with release of the tetraazaporphine ligand. The kinetic parameters of the dissociation were determined, and the reaction mechanism was discussed. The complexes were ranked with respect to their kinetic stability.
Kinetic stability of the dysprosium(III) complex with tetraazaporphine in water-acetic acid and methanol-acetic acid mixtures

, p. 445 - 449 (2008/10/09)
Water-soluble dysprosium tetraazaporphine complex with the acetylacetonate ion as an extra ligand was synthesized for the first time. Its kinetic stability in acetic acid solutions was studied. The complex was shown to undergo solvoprotolytic dissociation to form free tetraazaporphine. The kinetic parameters for dissociation reaction are determined and the mechanism of reaction is discussed.
Phthalocyanines and related compounds: XXXVI. Synthesis of tetraazachlorin and tetraazaporphine from succinonitrile

, p. 1306 - 1311 (2007/10/03)
A new method of synthesis of tetraazaporphine and a previously unknown tetraazachlorin via reaction of succinonitrile with lithium dimethylaminoethoxide in dimethylaminoethanol or with lithium pentoxide in pentyl alcohol, with simultaneous oxidation of intermediate hydrogenated forms with air oxygen is proposed. A possible scheme of the reaction is discussed, and optimal conditions for selective synthesis of both compouds in yields of up to 18% are found. The product obtained with lithium pentoxide contains an admixture of pentyloxytetraazaporphine. Tetraazachlorin is quantitatively oxidized to tetraazaporphine by short heating in acetic acid. The structure of tetraazachlorin is confirmed, and its electronic absorption spectra are discussed.
