Problems solved by technology

[0005] Aggregation-induced luminescent materials have broad application prospects in optoelectronic devices, chemical / biological sensors, etc. However, most of the existing fluorescent materials have ACQ effect, and there are few materials with AIE effect, so the research on AIE fluorescent materials is very important

Embodiment 1

[0069] 1. Synthesis of 4-formyl triphenylamine

[0070] Take a 100mL round-bottomed flask, add 30mL of anhydrous DMF to it, place the flask in an ice-water bath, slowly add 29.5mL of phosphorus oxychloride to it with a dropping funnel, stir for 30min after the dropwise addition, and then add 2.5 g of triphenylamine, the reaction device temperature is set to 45 ° C, stirred and refluxed for 14 hours. Naturally cool to room temperature after the reaction is over, pour the reacted mixed solution into 200 mL of ice water, add dropwise sodium hydroxide solution to adjust the pH to neutral while stirring, and extract with dichloromethane three times after stirring at room temperature for 2 hours. and dried with anhydrous magnesium sulfate, and after filtration, the filtrate was spin-dried with a rotary evaporator, and the resulting solid was used as a developing solvent with a 5:1 petroleum ether:ethyl acetate mixed solution, and was separated by silica gel column chromatography to ...

Abstract

The invention discloses a triphenylamine derivative with AIE characteristics, which is prepared by reacting 4-formyl triphenylamine with 2-aminobenzimidazole in the presence of a solvent and a catalyst by stirring and refluxing the reactants at 60-80 DEG C for 18-24 hours. The invention also discloses a preparation method and applications of the derivative. The triphenylamine derivative can be used as a pH probe to detect volatile organic acid and alkali. In addition, the triphenylamine derivative probe responds to mercury ions under neutral and alkaline conditions, and has potential application in detection of heavy metal, mercury ions.

Description

technical field [0001] The invention relates to the technical field of fluorescent materials, in particular to a triphenylamine derivative with AIE characteristics, its preparation method and application. Background technique [0002] Fluorescent materials have attracted the interest of many scholars due to their rich applications and broad development prospects. Fluorescent or colorimetric probes for the selective recognition of individual metal ion systems have been rapidly developed and attracted increasing attention in recent years. Most studies on fluorescent materials are carried out in dilute solutions, where the luminescent molecules can be regarded as isolated objects without interference from chromophores to study their excited state lifetimes, decay rates, and fluorescence efficiencies. However, most conventional fluorescent probes are almost insoluble in water, and often show weak or even no fluorescence due to aggregation-induced quenching at high water fractio...
