Abstract

The invention provides a thermotropic fluorescent color-variable coordination polymer containing [Cu414]n clusters as well as a synthesis method and application thereof and relates to a thermotropic fluorescent color-variable coordination polymer as well as a synthesis method and application thereof. The thermotropic fluorescent color-variable coordination polymer containing [Cu414(C14H14N4)2]n clusters is used for solving the technical problems of single emitted light color, short fluorescent life and high raw material cost of an existing thermotropic fluorescent color-variable material. The thermotropic fluorescent color-variable coordination polymer containing [Cu414(C14H14N4)2]n clusters has a molecular formula of [CU414(C14H14N4)2]n, and has a structural formula as shown in the specification. A preparation method comprises the following steps of mixing raw materials; heating with water; cooling; filtering; drying. The method has the beneficial effect that the yield is about 60%. The polymer presents yellow fluorescence at room temperature, and is good in single color property; a thermotropic fluorescent color-variable material capable of changing yellow fluorescence into red fluorescence is obtained by virtue of regulating different temperatures. The polymer is doped into polymethyl acrylate, so that the strength is improved, raw materials are easily available, the preparation method is simple, and the polymer can serve as a raw material for a fluorescent material film.

Description

technical field [0001] The invention relates to a thermoluminescent color-changing coordination polymer, a synthesis method and application thereof. Background technique [0002] Thermofluorochromic materials refer to functional materials whose visible absorption spectrum changes when some compounds or mixtures are heated or cooled. It has the characteristic that the color changes with temperature. The temperature at which the color changes occurs is called the color change temperature. A good thermochromic material can see the color change with the naked eye, but so far, thermochromic materials that can see the color change by heating or cooling are still rare. At present, most of these materials have a single luminescent color, short fluorescence lifetime, and high raw material cost. Contents of the invention [0003] The present invention aims to solve the technical problems of single luminescent color, short fluorescent life and high cost of raw materials of current t...
