Abstract

The invention relates to the field of colored fluorescent materials, in particular to an orange organic supermolecular polymer as well as a preparation method and an application thereof. The chemicalcomposition of the supermolecular polymer is [(H3pbod)](Hbpep)(H2O)]n, wherein [H3pbod]<-> is shown in formula I and [Hbpep]<+> is shown in formula II. The invention also provides a preparation methodof the supermolecular polymer. According to the method, the supermolecular polymer is prepared from H4pbod, bpep and HNO3 as raw materials and a mixed solution of acetonitrile and water as a solventwith a solvothermal synthesis method. The method is simple and efficient, the yield can reach 99%, and the purity of synthesized crystal samples is high; the obtained crystal samples stably exist in solvents such as water and acetonitrile, begin to decompose at about 325 DEG C and have higher thermal stability; the maximum fluorescence emission peak is at 560 nm under excitation of wavelength 413nm; the crystal samples are orange and yellow respectively under natural light and 365nm ultraviolet.

Description

technical field [0001] The invention relates to the field of colored fluorescent materials, in particular to an orange supramolecular polymer and its preparation method and application. Background technique [0002] Fluorescent materials can absorb high-energy photons to generate low-energy visible light, and have been widely used in lighting, display and many other fields. Fluorescent materials can be divided into colorless fluorescent materials and colored fluorescent materials. Colored fluorescent materials can not only reflect part of the visible light in sunlight, but also absorb ultraviolet rays and emit visible light. A popular type in the fields of materials, pigments (paints or dyes). [0003] Due to the over-exploitation of natural resources and the influence of environmental protection and other factors, the development of new organic fluorescent materials has been paid more and more attention by people. Colored organic fluorescent materials have rich colors and...
