摘要： 1. A dispersant for stabilizing nanoparticles, in particular inorganic non-metallic nanoparticles is described. Said dispersant comprises at least one anchor group A, and at least one spacing group R covalently linked to said anchor group, said anchor group A is an unsaturated at least partially conjugated substituted six- membered homocyclic ringand comprises two surface interacting oxygen or hydroxy substituents on adjacent carbon atoms in the ring and. at least one further electro-negative substituent.
