57 Abstract AB [DE] Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von mesoscopischen Ringen unter Einsatz einer colloidalen dreidimensionalen Matrize. Ferner betrifft die vorliegende Erfindung die Verwendung einer colloidalen dreidimensionalen Matrize zur Herstellung von mesoscopischen Ringen und mesoscopische Ringe, welche nach dem erfindungsgemäßen Verfahren herstellbar sind, sowie mesoscopische Ringe mit einem Außendurchmesser von 50 bis 999 nm, einem Innendurchmesser von 20 bis 300 nm, einer Höhe von 2,5 bis 300 nm, einem Verhältnis von Innendurchmesser zu Außendurchmesser von 0,1 bis 0,8 und einem Verhältnis von Höhe zu Außendurchmesser von 0,02 bis 0,3.
[EN] Preparing mesoscopic rings (I) comprising contacting a three-dimensional colloidal matrix with a fluid formulation comprising a solvent, polymerizable monomer (component B1) or a substance (component B2) soluble in the solvent; removing the solvent forming under the developing (I) from B1 or B2; polymerizing the appropriate polymers of B1 (when B1 is used) to form (I); removing the matrix; and dispersing the obtained (I), is new. Preparation of mesoscopic rings (I) comprises: (A) contacting a three-dimensional colloidal matrix developed from a dense packing of colloidal particles (having one or more contact points) with a fluid formulation comprising a solvent (component A), a polymerizable monomer (component B1) or a substance (component B2) (that remains in solid form after removal of a solvent) soluble in the solvent; (B) removing the solvent forming under the developing mesoscopic rings from component B1 or component B2; (C) polymerizing the appropriate polymers of component B1 (when B1 is used) to form the mesoscopic ring; (D) removing the three-dimensional colloidal matrix; and (E) dispersing the obtained mesoscopic rings. An independent claim is also included for mesoscopic rings obtained by the method.
