光电应用之混成材料;HYBRID MATERIAL FOR OPTOELECTRONIC APPLICATIONS

摘要

一种用于发光二极体的混成材料，其包含：a)包含式(I)及(II)之重覆单元的有机聚矽氮烷材料，;其中该等符号及标志具有下列意义：R 1 系C2-C6-烯基或C4-C6-二烯烃基(alkadienyl)；R 2 系H或有机基团；R 3 系H或有机基团；R 4 系H或有机基团；R 5 系H或有机基团；x系0.001至0.2；及y系2x至(1-x)，其前提为x+y1，及若R 2 系H时，y可系0；及b)具有在1至30奈米之范围内的平均直径的无机奈米粒子，其以包含C1-C18-烷基及/或C1-C18-烯基的封端剂进行表面修改，该混成材料系有用作为LED的封装材料。; R 2 is H or an organic group; R 3 is H or an organic group; R 4 is H or an organic group; R 5 is H or an organic group; x is 0.001 to 0.2; and y is 2x to (1-x), with the proviso that x+y1 and that y can be 0 if R 2 is H, and b) inorganic nanoparticles having a mean diameter in the range of from 1 to 30 nm, which are surface modified with a capping agent comprising a C1-C18-alkyl and/or C1-C18-alkenyl group, is useful as encapsulation material for LEDs.
