Disclosed is a method of coating a particle, the method comprising contacting (i) a particle, wherein the surface of the particle comprises functional groups suitable to undergo a coupling reaction with at least a hydroxyl group, a halogen group or an akloxy group, with (ii) molecules of formula (Ia) and/or (Ib): (Ia) or (Ib) wherein A is a metal or a metalloid, R1 and (in formula (Ia)) R2 are halogen or an alkoxy group and R20 is OH, halogen or an alkoxy group. G1 is an aliphatic; cycloaliphatic, aromatic, arylaliphatic or arylcycloaliphatic spacer and E is a functional group. Molecules of the compound of general formula (Ia) and/or (Ib) are immobilized on the surface of the particle by a coupling reaction between functional groups on the surface of the particle and moieties R20 . |
