Efficient Electroluminescence of Two Heteroleptic Platinum Complexes with a 2-(5-Phenyl-1,3,4-oxadiazol-2-yl)phenol Ancillary Ligand

Two new platinum(II) cyclometalated complexes with 2-phenylpyridine (Pt1) and 2-(4-trifluoromethyl)phenylpyridine (Pt2) as the main ligands and 2-(5-phenyl-1,3,4-oxadiazol-2-yl)phenol (pop) as the electron-transporting ancillary ligand were developed. The photoluminescence quantum efficiency yields of both green Pt1 and Pt2 phosphors (λmax 490 and 496 nm) are 20.0% and 31.0% in CH2Cl2 solutions, respectively. Efficient OLEDs (organic light emitting diodes) of ITO/TAPC (bis[4-(N,N-ditolylamino)phenyl]cyclohexane, 40 nm)/Pt1 or Pt2 (5 wt %):TCTA (4,4′,4″-tri(carbazoyl-9-yl)triphenylamine, 10 nm)/Pt1 or Pt2 (5 wt %):2,6DCzPPy (2,6-bis(3-(carbazol-9-yl)phenyl)pyridine, 10 nm)/TmPyPB (1,3,5-tris(m-pyrid-3-ylphenyl)benzene, 40 nm)/LiF (1 nm)/Al (100 nm) were fabricated. Particularly, device G1 based on complex Pt1 with 5 wt % doped concentration showed superior performance with a maximum current efficiency (ηmax,c) of 55.6 cd A-1, a maximum power efficiency (ηmax,p) of 52.2 lm W-1, and a maximum external quantum efficiency (EQEmax) of 18.0%. Device G2 with the Pt2 emitter displayed lower efficiency rolloff with ηc values of 48.5 and 43.1 cd A-1 as the luminance reached 5000 and 10000 cd m-2, respectively. These research results demonstrate that the Pt(II) complexes with an ancillary ligand attached with the 1,3,4-oxadiazole group have promising applications in efficient OLEDs.

A catalytic asymmetric Ugi-type reaction with acyclic azomethine imines

An unconventional Ugi: A catalytic asymmetric Ugi-type reaction can be realized by use of N'-alkylbenzohydrazide, instead of a conventional amine, in the presence of an axially chiral dicarboxylic acid. The reaction proceeds through a key acyclic azomethi

Synthetic Approaches to Phthalazines: C-N Bond Cleavage in 2'-Benzylbenzohydrazides During Reaction with Polyphosphoric Acid

Reaction of 2'-benzylbenzohydrazides with concentrated polyphosphoric acid gave 2,5-diaryl-1,3,4-oxadiazoles and a polybenzyl.Cyclodehydration to phthalazines was not observed.It is inferred from product substitution patterns that CH2-N bond cleavage occurs with polybenzyls forming from the benzyl moiety and oxadiazoles from the benzohydrazide fragment.Other reported reactions which generate benzyl fragments lead to bibenzyl and are considered to involve trapping of the cleavage products within a solvent cage.The observed production of polybenzyls is therefore interpreted in terms of the formation of free benzyl fragments.A tetrahydrophthalazine derivative was produced from the addition of diethyl azodicarboxylate to the photodiene of o-methylbenzophenone, but this could not be converted into a phthalazine.
