Embodiment 1

[0054] Weigh 320mg (0.45mmol) of TBrSDF and 160mg (0.94mmol) of 1,4-benzenediboronic acid, mix them into a 250ml two-necked flask, and vacuum and blow nitrogen three times each to exhaust the air in the flask.

[0055] Add 30ml of toluene, which has been dehydrated in advance, into the two-necked flask, and stir for 10min. Then weigh 3g of potassium carbonate and dissolve in 10ml of water, measure 1ml of Aliquant 336 phase transfer catalyst and dissolve in 5ml of anhydrous toluene, put them into two-necked flasks under the protection of nitrogen, and evacuate the nitrogen once each.

[0056] Finally, 0.026 g of tetrakis(triphenylphosphine)palladium was weighed and added into a two-necked flask, heated to 110° C., and refluxed for 4 days to stop the reaction.

[0057] The reaction solution was cooled to room temperature, diluted with water, extracted with toluene, the extract was rotary evaporated to remove the solvent, and then 300ml of anhydrous methanol was added for alcohol...

Abstract

The invention discloses a conjugated microporous organic polymer based on spiro[3,3]heptane-2,6-spirofluorene having a structural formula shown in formula (I), which is based on spiro[3.3]heptane-2, 6‑di‑(2', 2", 7', 7"‑tetrabromo) spirofluorene is the first building block monomer, which is respectively coupled with the second building block monomer with different linkages through SuZuki coupling reaction or Sonogashira cross-coupling prepared by the linked reaction. The repeating unit of the conjugated microporous organic polymer of the present invention has three distorted spiro atom centers, which can effectively prevent the accumulation of polymer chains and better realize the synthesis of the conjugated microporous organic polymer, and by changing the second building unit The body regulates the pore size of the polymer, so that the polymer has permanent holes and good stability, and can be used as a light-emitting layer material of an organic electroluminescent device.

Description

technical field [0001] The invention belongs to the technical field of preparation of porous organic polymers, and relates to a conjugated microporous organic polymer based on spiro[3.3]heptane-2,6-spirofluorene and a preparation method thereof. Background technique [0002] Microporous Organic Polymers (MOPs) are a new class of porous materials that are interconnected by light elements (C, H, O, N, B, etc.) through covalent bonds. [0003] MOPs have unique properties such as high specific surface area, low skeletal density, and high porosity. Meanwhile, most MOPs have good stability under harsh conditions such as acid-base, solvent, moisture, and high temperature. In addition, MOPs can regulate the structure, size and functionalization of micropores by selecting reactive monomers with different functional groups and different synthesis methods. [0004] At present, MOPs mainly include Polymers of Intrinsic Microporosity (PIMs), Hyper-cross-linked Polymers (HCPs), Covalent...
