Description
Technical Field
The invention belongs to the technical field of preparation and application of sensing materials, and particularly relates to a derivative based on pyrrolo-pyrrole-Dione (DPP) and a preparation method and application thereof.
Background
As a transition metal element, iron is widely found in nature. Iron is important for human production and life, history records exist, and iron is utilized in spring, autumn and warring countries as early as the time. Iron exists in nature primarily as iron ore and ions, primarily involving two valence states, divalent and trivalent. The detection of iron ions is crucial in the fields of life health, environmental protection and industrial production. Iron plays an important role in the synthesis of hemoglobin in living systems, and in some redox reaction systems in the human body, iron also serves as a carrier for some enzymes and electron transfer, and is also an important component of catalase, cytochrome and the like. The deficiency of iron will lead to a decrease in hemoglobin content and a decrease in physiological activity, causing a significant decrease in the amount of oxygen carried by hemoglobin, thereby affecting the supply of nutrients and oxygen in the brain. If a human body is lack of iron for a long time, iron deficiency anemia can be caused. However, excessive iron intake also poses a health risk, for example, if high concentrations of iron are ingested, the risk of hemochromatosis, heart disease and certain cancers increases. The excessive existence of iron ions in water also brings huge pressure to environmental protection, and with the expansion of human activity areas and the diversification of water source development forms, the causes of water source pollution in nature include not only artificial discarded wastes, but also chemical changes of minerals in water sources and other factors. Iron ions in the water source are deposited through complex chemical reactions and can enter the water source again in the form of ions under an acidic condition, so that the water source is polluted newly. Iron ions also present a certain hazard in industrial production, for example, in beer production, even if very small amounts of iron ions are present, they accelerate the aging process of beer, thereby reducing the quality of beer. In the aquaculture industry, if iron ion deposits are attached to the surfaces of crab eggs, the oxygen and sunlight intake of the crab eggs is insufficient, so that the vitality of embryos is reduced. In view of the great influence of iron ions on a plurality of fields, it is important to develop a method capable of rapidly identifying, accurately detecting and monitoring iron ions in real time.
Until now, a series of methods for detecting the content of metal ions, such as instrumental analysis methods of inductively coupled plasma atomic emission spectrometry, high performance liquid chromatography, capillary electrophoresis, polarography, etc., have been developed. These methods have a low detection limit for metal ions, can identify metal ions having a very low concentration, and can accurately quantify the content of each metal ion. However, these methods usually require expensive instruments, specialized technical operators, and are difficult to implement in field detection, real-time monitoring, etc. Fluorescent probes have received much attention in recent years due to their advantages of high sensitivity, low detection limit, high specificity, and low cost. In general, a fluorescent probe molecule is composed of a chromophoric group and a recognition group, the chromophoric group determines the luminescent property and sensitivity of the fluorescent probe, and the recognition group determines the specificity and selectivity of the fluorescent probe. Compared with the traditional instrument analysis method, the method for identifying and detecting the existence and the content of the metal ions by using the fluorescent probe has the advantages of high sensitivity, strong selectivity, short response time, low cost, real-time monitoring, simplicity in operation, capability of realizing outdoor operation and the like. At present, some methods for detecting Cu have been developed2+、Pb2+、Hg2+Fluorescent probes for heavy metal ions. pyrrolopyrrole-Dione (DPP), a bright red high performance pigment, has received much attention due to its superior light stability, thermal stability, and strong absorption and emission in the visible region. Due to these excellent optical properties, DPP plays an important role in research and development in the fields of solar cells, organic field effect transistors, organic light emitting diodes, and the like. For fluorescent probes, DPP is a chromophore with superior properties. Long wavelength excitation and emission are critical to reduce scattering and ensure that background emission is minimized, while DPP excites and emits in the very long wavelength region. Because of these excellent properties of DPP, it has been studied by many groups to use DPP as a chromophore to attach different recognition groups to accomplish detection of different analytes. For example: a mercury ion probe in which a thioether chain is linked to DPP, a citric acid probe in which a pyridine ring is linked to DPP, and a hydrogen sulfide probe in which a nitroethylene chain is linked to DPP.

Preparing a ferric trichloride aqueous solution with the solubility of 10 mmol/L: 2mL of the ethanol solution of the compound 5-1 with the concentration of 2. mu. mol/L is placed in a quartz cuvette, and 10mmol/L of an aqueous solution of ferric trichloride is gradually added dropwise into the cuvette by using a pipette gun, wherein 2. mu.L of the aqueous solution of ferric trichloride is added dropwise each time. And (3) recording the fluorescence intensity of the ethanol solution of the compound 5-1 after the ferric trichloride aqueous solution is added in each time by using a fluorescence spectrophotometer. The result shows that the compound 5-1 used as the ferric ion probe in the invention has high sensitivity to ferric ions, and when the concentration of ferric ions in the cuvette reaches only 190 mu mmol/L, the fluorescence is almost completely quenched, as shown in figure 1, the figure 1 is a fluorescence titration curve in which the compound 5-1 is used as the ferric ion probe, and the compound 5-1 is dissolved in ethanol and titrated with ferric trichloride aqueous solution. The probe solutions before and after exposure to ferric ion showed a large visual difference as observed under a 365nm uv lamp, as shown in fig. 2, which is a photograph of compound 5-1 in ethanol, compound 5-1 dissolved in ethanol and exposed to ferric ion under a 365nm uv lamp.

For the other ions, no similar phenomena occurred, indicating that there was no significant interaction of the other ions with the probe molecule 5-1. The specific recognition capability of the probe molecule 5-1 on ferric ions is further verified.
