Paragraph 0025, (2017/08/29)
The invention relates to a method for preparing tyrosine framework type periodic mesoporous organosilicas materials. The method for synthesizing the tyrosine framework type periodic mesoporous organosilicas materials includes esterifying tyrosine in methanol by the aid of thionyl chloride; carrying out acrylation on the tyrosine by the aid of hydrazine hydrate and carrying out reaction on the tyrosine and isocyanic acid propyltriethoxysilane to obtain tyrosine organosilicas precursors; hydrolyzing the tyrosine organosilicas precursors and surfactants under acidic conditions to form PMO (periodic mesoporous organosilicas) materials; removing the surfactants from the PMO materials by means of extraction to ultimately form PMO materials with specific morphological structures. The tyrosine is used as a substrate. The methanol is used as a solvent. The method has the advantages synthesis reaction raw materials are simple and are easily available, synthesis operation is simple and convenient and is easy to implement, and the method is high in yield and low in energy consumption and is safe and inexpensive; the tyrosine framework type periodic mesoporous organosilicas materials prepared by the aid of the method have important application prospects in the fields of biosensors, catalyst carriers, adsorbents, sustained-release medicine capsules, chromatographic separation and the like.
