Solid hyperbranched aryl-conjugated aluminum-containing polycarbosilane and its preparation method and application
A polycarbosilane and aryl technology, which is applied in the field of solid hyperbranched aryl-conjugated aluminum-containing polycarbosilane and its preparation, can solve the problems of poor film-forming properties, poor stability of organic light-emitting materials, and poor luminous efficiency and purity. Advanced problems, to achieve the effect of high emission purity and good anti-oxidation cross-linking

Embodiment 1
[0038] 1) Put 50g of polydimethylsiloxane (PMDS) in a closed 300ml autoclave, raise it to 300°C at 10°C / min under the protection of argon, vacuumize and keep it for 2 hours, and then fill it with argon to keep The pressure in the system is 101Kpa, then rise to 390°C at 1°C / min, and keep warm for 3h. After the reaction was completed, after the temperature in the reaction kettle was naturally cooled to room temperature, n-hexane was added to dissolve the product, filtered, and n-hexane was removed in a vacuum to finally obtain pale yellow solid polycarbosilane (PCS).
[0039] 2) The product in step 1) was ground and soaked in absolute ethanol, stirred for 12 hours, the filtered product was rinsed three times with absolute ethanol and then dried in a vacuum oven at 60°C to obtain a light yellow solid product.
[0040] 3) Take 10g of the product in step 2), grind it into powder and mix it with 1g of aluminum acetylacetonate (Al(AcAc) 3 ) powders were evenly mixed and placed at th...
