Embodiment 1

[0040] The synthetic reference patent of 2-(3'-bromo-phenyl)-pyridine [Paul F. Ranken, Baton La. Rouge,, U.S. Patent 4,554,352].

[0041] Add 2-phenylpyridine (1 mole), anhydrous aluminum trichloride (1.2 mole), nitrobenzene (4.9 mole) in the 500ml there-necked flask with constant pressure funnel, thermometer, under nitrogen protection, be heated to 85-95°C. Liquid bromine (1.2 moles) was slowly dropped into the mixed solution and reacted at 85-95°C for 12 hours. The reaction mixture was poured into crushed ice. After the bromine was washed away, the product was purified by column chromatography to obtain a white needle-like solid.

[0042]

Embodiment 2

[0044] The synthesis of 5-bromo-2-phenylpyridine refers to [Lamansky, S.; Djurovich, P.; Murphy, D.; Abdel-Razzaq, F.; Kwong, R.; Tsyba, I.; Bortz, M.; Methods reported by Mui, B.; Bau, R.; Thompson, M.E.; Inorganic Chemistry. 2001, 40, 1704-1711]

[0045] Weigh 6.48 g of anhydrous zinc chloride, 0.49 g of tetrakis(triphenylphosphine) palladium, and 5.5 g of 2,5-dibromopyridine in a glove box, and inject 25, 25, and 35 ml of THF into solutions respectively.

[0046]31.3 ml of BuLi and 20 ml of THF were added to a 500 ml three-necked flask equipped with a constant pressure funnel and a thermometer. After liquid nitrogen was cooled to -78°C, a solution containing bromobenzene 5ml / THF (25ml) was added dropwise, and the reaction was continued at -70°C for 40min. Then the zinc chloride / THF solution was added dropwise from the constant pressure funnel at -70°C. After gradually raising the temperature to room temperature, the reaction was carried out for 30 minutes. Tetrakis(triph...

Embodiment 3

[0049] The synthetic reaction steps of 5-bromo-2-(4'-methylphenyl)-pyridine are as in Example 2

[0050] The bromobenzene in the raw material is changed into p-bromotoluene, finally obtains 3.58 grams of light yellow powder,

[0051] The yield was 60.8%. 1 HNMR and GC-MASS tests showed that it was the target product.

Abstract

The invention discloses a super-branch electrical phosphorescent light conjugated polymer which takes metal complex as core and the application in the light-emitting diode, luminescent layer of the panel display, and reactive layerof the solar battery. The process is simple and easy to carry out and have a high application value.

Description

technical field [0001] The invention relates to a polymer containing a metal complex, in particular to a hyperbranched electrophosphorescent conjugated polymer with a metal complex as the core. [0002] The invention also relates to the application of the hyperbranched electrophosphorescent conjugated polymer with the metal complex as the core in light-emitting diodes, light-emitting layers of flat panel displays, and active layers of solar photovoltaic cells. Background technique [0003] Since Japanese scientist Hideki Shirakawa discovered that polyacetylene conducts electricity in 1977, this conductive polymer, known as the "fourth generation polymer material", has attracted many scientists for its outstanding photoelectric properties. Compared with inorganic materials with the same or similar applications, conductive polymers have the advantages of low density and easy processing. Due to the conjugation characteristics of this kind of material structure, it can transpor...
