Abstract:
1. A method for controlling a structure of a polysilsesquioxane prepared from a monomer represented by Chemical Formula 1, comprising: preparing an aqueous organic solution comprising the monomer represented by Chemical Formula 1, an organic solvent, water and a catalyst; and selectively preparing a polysilsesquioxane with a cage structure represented by Chemical Formula 2 or a polysilsesquioxane with a ladder structure represented by Chemical Formula 3 by adjusting the amount of the organic solvent or water in the aqueous organic solution, wherein the amount of the organic solvent is adjusted to 70 wt % or more or 30 wt % or less based on the entire aqueous solution and the molar ratio of R wherein the amount of the organic solvent is adjusted to 31 to 69 wt % based on the entire aqueous solution and the molar ratio of R wherein R R n is from 2 to 100,000.
