Abstract
The invention relates to an organic polyspiralgrid nanopolymer material and a preparation method thereof, and belongs to the field of nanotechnology and organic electronics. The structure of the organic polyspiralgrid nanopolymer material is composed of grids containing a spiro ring that serves as a repeat unit to form a special nano polymer, and the structure shares the spiro ring structure. A synthetic method thereof relates to a synthon containing the spiro ring, and by means of a Friedel-Crafts reaction, an organic spirogrid and a nano polymer thereof are built. By means of reasonable molecular design and the Friedel-Crafts reaction with the advantages of being mild in reaction condition, high in yield, high in selectivity, simple in posttreatment, green, free of toxicity and the like, the problems that a traditional polymer molecule is complex in synthesis step, toxic in posttreatment, large in pollution and the like are solved.
