Embodiment 1

[0043] The synthesis of target compound p-CN (genus structural formula I):

[0044] Bromotriphenylethylene (3.35g, 10mmol), 4-cyanophenylboronic acid (2.2g, 15mmol) and 0.18g tetrakis(triphenylphosphine)palladium were placed in a 100mL two-necked round bottom flask, and the reaction system was deoxygenated. 15mL K 2 CO 3 (6.21g, 45mmol) aqueous solution and 45mL tetrahydrofuran were deoxygenated, poured into a round bottom flask, and refluxed for 20 hours under the protection of nitrogen. After the reaction was completed, it was cooled to room temperature, 100 mL of water was added, extracted with dichloromethane (100 mL×3), and the organic phases were combined. The organic phase was dried with anhydrous sodium sulfate, filtered, and rotary evaporated under reduced pressure to obtain a crude product. The crude product was purified by silica gel column chromatography using petroleum ether and dichloromethane as eluents to obtain 3.03 g of white powder with a yield of 85%.

Embodiment 2

[0048] The synthesis of target compound m-CN (genus structural formula I):

[0049] Referring to the method of Example 1, the target compound was synthesized with 3-cyanophenylboronic acid instead of 4-cyanophenylboronic acid, and a white powder was obtained with a yield of 83%.

[0050] The synthetic route is as follows:

[0051]

Embodiment 3

[0053] The synthesis of target compound p-OH (belonging to structural formula I):

[0054] Referring to the method of Example 1, the target product was synthesized by replacing 4-cyanophenylboronic acid with 4-hydroxyphenylboronic acid, and a white powder was obtained with a yield of 88%.

[0055] The synthetic route is as follows:

Abstract

The invention discloses a luminescent material and a synthesis method and application thereof. The invention provides the luminescent material which has mechanoluminescence and aggregation-induced emission properties at the same time, and also provides the synthetic method of the luminescent material, and the mechanoluminescence property of the luminescent material can have good application prospects in the fields of stress sensors, anti-counterfeiting marks and the like.

Description

technical field [0001] The invention relates to the technical field of organic material synthesis, in particular to a luminescent material and its synthesis method and application. Background technique [0002] Materials that can directly emit fluorescence or phosphorescence under the stimulation of external mechanical forces (grinding, friction, scratching, cutting, shearing, crushing, extrusion, etc.) are called Mechanoluminescence or Triboluminescence materials. Mechanoluminescence materials have great application prospects in the fields of sensing, monitoring, lighting and anti-counterfeiting (Chem 2018, 4, 943). Mechanoluminescence materials can be divided into inorganic materials, metal-organic complex materials and pure organic materials. Pure organic mechanoluminescent materials have the advantages of simple synthesis, low cost, less toxicity, and easy adjustment of luminescent range. However, the fluorescence of ordinary organic light-emitting materials often has ...
