Abstract: The invention relates to compounds of formula (I) wherein the groups A and B represent independently from each other —CH?CH—, or —C?C—, the terms t, u, v, w represent, independently from each other, values ranging from 0 to 9, the groups Y1 and Y2 can represent independently from each other an alkyl group (linear, branched or substituted) carrying from 1 to 9 carbon atoms, the groups Z1, Z2, Z3, and Z4 can represent independently from each other a chemically reactive group W, such as OH, NH2, SH, the groups Z5 and Z6 represent independently from each other a hydrogen atom, silica nanoparticles functionalized by these compounds, and their use as drugs.
