Transition metal complex used as phosphorescent material and application thereof

The invention belongs to the technical field of organic photoelectric materials, and particularly relates to a transition metal complex used as a phosphorescent material and application. A class I ligand and a class II ligand are adopted, and the frontier orbitals of the two ligands make an important contribution in the frontier orbital in a light-emitting state, so that the ligands can adjust andimprove the light-emitting color and efficiency of the phosphorescent material; meanwhile, the molecular weight of the material is not very large, and further material sublimation purification and device preparation are facilitated.

Transition metal complex used as phosphorescent material and application thereof

The invention belongs to the technical field of organic photoelectric materials, and particularly relates to a transition metal complex used as a phosphorescent material and application of the transition metal complex. Based on the brand-new material design concept, in the system, the names of a main ligand and an auxiliary ligand are not used any more because the selection and matching of the twoligands have very important influence on the properties of the material. According to the invention, two functional ligands are adopted, and front tracks of the two ligands both participate in an electronic structure in a luminous state, so that the two ligands can adjust and improve the luminous color and efficiency of the phosphorescent material; meanwhile, the molecular weight of the materialis not very large, and further material sublimation and purification and device preparation are facilitated.

Transition metal compound serving as phosphor material and application thereof

The invention relates to a transition metal compound serving as a phosphor material and application thereof. The transition metal compound has the molecular structure shown in the formula (1): the formula (1) is shown in the description. The transition metal compound contains a novel auxiliary ligand I, the ligand I has the same auxiliary coordination as commonly-used acetylacetone, but the difference is that the bidentate ligand is combined with metal to form a four-membered ring structure, meanwhile, coordinate S and Se elements have relatively high polarity properties so that combination with the core of the metal can be more stable, the ligand is matched with a main ligand II, so that the wavelength of the light emitted by the transition metal compound can be adjusted from blue-green light to red light, and accordingly the photoelectric property of the transition metal compound can be adjusted.

The invention discloses a binuclear metal organic complex and preparation method and application thereof. The binuclear metal organic complex has a binuclear structure. The preparation method is as follows: the binuclear metal complex is synthesized by using 2-Pyridine-Benzimidazole or 2-Pyrimidine-Benzimidazole as a bridging ligand. The advantages of the binuclear metal organic complex are: (1) the luminescence efficiency of the binuclear metal organic complex is greatly improved by synthesizing the binuclear metal organic complex with the binuclear structure; and (2) The binuclear metal organic complex is a new structure, has great significance in application in organic electronic devices, and lays a foundation for subsequent research and production.

Photophysical properties and OLED performance of light-emitting platinum(ii) complexes

The synthesis, photophysical properties and application as emitters in solution-processed multi-layer organic light-emitting diodes (OLEDs) of a series of blue-green to red light-emitting phosphorescent platinum(ii) complexes are reported. These complexes consist of phenylisoquinoline, substituted phenylpyridines or tetrahydroquinolines as C^N cyclometalating ligands and dipivaloylmethane as an ancillary ligand. Depending on both the structure of the C^N cyclometalating ligands and the dopant concentration in the matrix, these platinum(ii) complexes exhibit different aggregation tendencies. This property affects the photoluminescence spectra of the investigated compounds and colour-stability of the fabricated OLEDs. Using the blue-green to yellow-green emitting complexes, the best results were obtained with the 2-(4- trifluoromethylphenyl)-5,6,7,8-tetrahydroquinoline based platinum(ii) complex. A maximum luminous efficiency of 4.88 cd A-1 and a power efficiency of 4.65 lm W-1, respectively, were achieved. Employing the red emitting phenylisoquinoline based complex as an emitter, colour-stable and efficient (4.71 cd A-1, 5.12 lm W-1) devices were obtained.

Charge-transfer and ligand-localized photophysics in luminescent cyclometalated pyrazolate-bridged dinuclear platinum(II) complexes

We present the synthesis, photophysical characterization, and electrochemistry of three series of cyclometalated binuclear platinum(II) complexes, each bridged by two 3,5-disubstituted pyrazolate ligands (μ-R 2pz). These neutral compounds have the general formula [C NPt(μ-R2pz)]2, where C N is a cyclometalating ligand corresponding to 2-(2′-thienyl)pyridine (thpy), 1-phenylisoquinoline (piq), or 7,8-benzoquinoline (bzq) with R = H, Me, iPr, Ph, corresponding to series I-III dimers, respectively. Systematic variation of the cyclometalating ligands in addition to the bridging pyrazolates renders colorful structures exhibiting a range of electrochemical and spectroscopic behavior with absorption and photoluminescence properties tuned over a wide portion of the visible spectrum. Steric bulk introduced into the 3,5-positions on the pz bridges readily modulates intramolecular d8-d8 metal-metal σ interactions strongly affecting the frontier orbitals' electronic structure, manifested by changes in absorption and emission energy, excited-state lifetime, and photoluminescence quantum yield. Cyclic voltammetry revealed the presence of two very closely spaced reversible CN ligand-based reductions ranging between -1.97 and -2.56 V vs Fc+/Fc, and the first metal-metal-centered oxidation wave was found to be reversible in dichloromethane and irreversible in coordinating THF in most instances. All the complexes of series I displayed triplet ligand-localized excited states at all temperatures, while an increase of steric bulk in the pz bridge in the two other molecular series resulted in a variation of photophysical behavior ranging from charge transfer to ligand localized, including admixture behavior.
