A kind of organic porous polymer and its preparation and application

Abstract

The invention discloses an organic porous polymer represented by the following general structural formula, which is constructed with pyrene and 9,9-dioctylfluorene as monomers: the organic porous polymer can be used as an organic electroluminescence material, White light-emitting organic electroluminescent materials are prepared by doping other small-molecule organic electroluminescent materials with complementary emission colors. Other small-molecule organic electroluminescent materials doped can enter the pores of the organic porous polymer to maintain the single-phase property of the polymer, avoid phase separation and interface degradation caused by doping, and keep the luminescent color stable.

Description

technical field

Embodiment 1

[0051] Example 1: Synthesis of an organic porous polymer whose building monomer 1,3,6,8-tetra-substituted pyrene accounts for 1% of the total molar amount of the polymer.

[0052] 1), the synthesis of 1,3,6,8-tetrabromopyrene.

[0053]

[0054] In a 250ml three-necked flask, add 3.26g (10mmol) of pyrene, vacuumize through N 2 3 times each to fully exhaust the air in the flask. 50 ml of THF was added, stirred and mixed at room temperature for 30 min, and 0.6 g (25 mmol) of NaH was added to the flask in 5 times, with an interval of 15 min between each addition. Vacuum again and pass N 2 , dissolve 1.70g (4mmol) of pentatetrabromide in 20ml of THF, slowly drop it into a three-necked flask through an atmospheric separatory funnel within 30min, heat it to 50°C for 6h, then heat it up to 75°C to continue the reaction for 24h.

[0055] After the reaction, the mixed solution was rotary evaporated to remove THF, water was added, and CH 2 Cl 2 Extract 3 times, collect CH 2 Cl ...
