Abstract

Organosilica particles based on bridging polysilsesquioxanes for blocking ultraviolet rays, which have novelty components C and D in different ratios, which are covalently crosslinked within organosilica particles, whereby particles of different structure (porous or non-porous) and morphology can be obtained (spheres, cylinders or bean-shape) for use in UV protection. The role of component C is to provide potent absorption of UV rays, while component D may have a partial UV-protective effect, but its primary role is constructive, i.e. allows the construction of a desired structure of organosilica particles. Component C is based on triazine, and the organosilica particles are synthesized by mixing components C and D in different ratios, in a solution of surfactant in a solvent mixture composed of water and ethanol, in the presence of ammonia as a catalyst. Component C is obtained by reacting components A and B, where component A is mixed with component B in a ratio of 1: 3, in acetonitrile as a solvent, in the presence of N,N'-Dicyclohexylcarbodiimide (DCC) as a catalyst.
