    • The present invention provides an organosilicon nanocapsule, which includes: a nanoscale core A, which includes: at least one particle including at least one oxide or mixed oxide, KA—O, of at least one metal or semimetal selected from the group including main groups 2 to 6 of the Periodic Table, transition groups 1 to 8 of the Periodic Table, lanthanides, and mixtures thereof; and an organosilicon shell B, which includes: at least one organosilicon compound having the formula (Ia): (Si′O—)xSi—R  (Ia) wherein R is a linear, branched, cyclic or substituted alkyl group having from 1 to 50 carbon atoms; wherein x is a number from 0 to 20; wherein remaining free valences of Si are each independently (KA—O)—, SiO— or —Z; wherein remaining free valences of Si′ are each independently (KA—O)—, SiO—, —R, or —Z; wherein the Z's are each independently hydroxyl or alkoxy radicals; and wherein each Si and Si′ in the shell B have not more than one R group attatched thereto.
    • 本发明提供了一种有机硅纳米胶囊,其包括:纳米级芯A,其包括:至少一种包含至少一种选自包括主要基团的金属或半金属的金属或半金属的氧化物或混合氧化物KA-O的颗粒 周期表的2至6,周期表的过渡组1至8,镧系元素及其混合物; 和有机硅壳B,其包括:至少一种具有式(Ia)的有机硅化合物:其中R是具有1至50个碳原子的直链,支链,环状或取代的烷基;其中x是0至20的数 ;其中Si的剩余游离价分别独立地为(KA-O) - ,SiO-或-Z;其中Si'的剩余游离价各自独立地为(KA-O) - , - SiO-,-R或-Z; 其中Z各自独立地为羟基或烷氧基; 并且其中壳体B中的每个Si和Si'具有不多于一个R基团。
