Blue light conversion agent s-triazine derivatives for agricultural film and their preparation method and use method

Abstract

The invention relates to blue light conversion agent s-triazine derivatives for an agricultural film and their preparation method and use method, and belongs to the technical field of fluorescent materials, organic electroluminescence materials and agricultural film light-conversion materials. The blue light conversion agent s-triazine derivatives comprise 2,4,6-tri(1-naphthylethyl)s-triazine (TNNA-1) having a molecular formula of C39H27N3 and a three-branch structure, and 2,4,6-tri(2-naphthylethyl)s-triazine (TNNB-1) having a molecular formula of C39H27N3 and a three-branch structure. The preparation method has simple processes and adopts traditional easily-acquired chemical materials. The blue light conversion agent s-triazine derivatives as organic light-emitting materials having s-triazine derivative structures have high thermostability, high glass-transition temperatures and high launching light intensity. In agricultural film preparation, the blue light conversion agent s-triazine derivatives are uniformly distributed in the agricultural film so that the agricultural film has the bright and flat surface and controllable thickness. The blue light conversion agent s-triazine derivatives have a wide application range, can convert ultraviolet light into visible blue light, adopt easily acquired raw materials, have low prices, can be prepared by the simple preparation method and are suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a blue light conversion agent s-triazine derivative for agricultural film, a preparation method and an application method thereof, belonging to fluorescent materials or fluorescent marking materials, organic electroluminescent materials, organic thin film bipolar tube materials, and agricultural film light conversion materials technology field. Background technique [0002] Agricultural film is an important agricultural production material after seeds, fertilizers, and pesticides. It has the effect of warming up and preserving moisture in the soil. my country is the country with the largest production and use of agricultural film in the world, which is 1.6 times the sum of all other countries. Agricultural film has made an important contribution to increasing agricultural efficiency and increasing farmers' income. With the improvement of crop cultivation technology, agricultural films with various special functions have appear...

Problems solved by technology

Among them, inorganic rare earth fluorescent compounds have high fluorescence intensity, but there are problems of sharp peak emission and poor anti-attenuation performance. The world stock of rare earth metal elements is small and the cost is high; although metal-organic complexes have high luminous intensity and good photostability properties, but metal-organic complexes are not conducive to uniform dispersion into polymer resins, resulting in a decrease in the physical and mechanical properties of the film and affecting the light transmittance of the film; organic fluorescent pigments, such as the sulfide-type light-converting agent that has been reported more at present , although the spectral matching is good, but there are defects of deliquescence resistance and poor dispersion in agricultural film
