Embodiment 1

[0048] Embodiment 1, the synthesis of the star polymer material containing Ir complex and carbazole:

[0049] L 1 Synthesis:

[0050]

[0051] Add 1.5g (8.09mmol) of compound (1) into the reaction vessel, then flush it with nitrogen after anhydrous and oxygen-free treatment, and inject 120mL of dichloromethane and 30mL of triethylamine (225mmol) into the reaction system at 0°C , stirred for about half an hour, then added 10 mL (18.9 mmol) of compound (2) dropwise with a syringe, and gradually raised to room temperature to react overnight. Stop the reaction, add an appropriate amount of water, separate and extract the organic phases, combine, dry and spin dry, then separate with a silica gel column, the eluent is petroleum ether: ethyl acetate = 10:1. 1.80 g of yellow product was obtained, yield 67%.

Abstract

Production of star-shaped polymer with ionic iridium complex as nucleus and ATRP is simple and cheap. It can be used for organic polymer phosphorescent electroluminescent material, chemical biological sensor inspection, fluorescent micro-sphere material, and its has controllable molecular weight and structure.

Description

[0001] Patent field [0002] The invention belongs to the technical field of photoelectric materials, and in particular relates to a star-shaped polymer with an ionic iridium complex as a core, a synthesis method and application thereof. technical background [0003] Atom Transfer Radical Polymerization (ATRP) has been highly evaluated since it was reported by Wang Jinshan and others in 1995. Compared with traditional radical polymerization, ATRP is applicable to a wider range of monomers, easy to obtain raw materials, and implementation conditions It is relatively mild, and the most attractive thing is that its polymerization molecular weight is controllable and its molecular weight distribution is narrow. In principle, it can make all free radical polymerization monomers undergo controllable / living polymerization, and effectively modify the structure of existing polymers. , and can be directly used in the existing free radical polymerization process and equipment. What is pa...
