摘　　要：报道了在Ｃ６０与ＮＨ２（ＣＨ２）３Ｓｉ（ＯＣ２Ｈ５）３中的胺基反应生成Ｃ６０－ＮＨ２（ＣＨ２）３Ｓｉ（ＯＣ２Ｈ５）３物质后引入ｒ－缩水甘油醚基丙基三甲氧基硅烷［ＣＨ２ＯＣＨＣＨ２ＯＣＨ２ＣＨ２ＣＨ２Ｓｉ（ＯＣＨ３）３，３－Ｇｌｙｃｉ－ｄｏｘｙｐｒｏｐｌｔｒｉｍｅｔｈｏｘｙｓｉｌａｎｅ，简称ＫＨ５６０］与二甲基二乙氧基硅烷［（ＣＨ３）２Ｓｉ（ＯＣ２Ｈ５）２，Ｄｉｅｔｈｏｘｙ－ｄｉｍｅｔｈｙｌｓｉｌａｎｅ，简称ＤＴＤＳ］物质的溶胶－凝胶过程。成品之后的有机－无机复合材料表现了较强的机械性，弹性和抗激光损伤性。克服了Ｃ６０－ＮＨ２（ＣＨ２）３Ｓｉ（ＯＣ２Ｈ５）３物质直接固化后的脆性。块体材料能在机器上手工抛光而不破裂，加工成实验所需的光学面。比表面积测试（ＢＥＴ）实验显示这种材料的微孔表面积极其小，为０．６５０２ｍ２／ｇ。用ＹＡＧ调Ｑ、脉宽１０ｎｓ、波长５３２ｎｍ的激光器实现了这类新型材料的光限制效应。The sol gel process of C 60 NH 2(CH 2) 3Si(OC 2H 5) 3(C 60 3 Aminopro pyltriethoxysilane or C 60 KH550) mixing with CH 2OCHCH 2O(CH 2) 3Si(OCH 3) 3 (3 Glcidoxypropltrimethoxysilane or KH560) and (CH 3) 2Si(OC 2H 5) 2 (Diethoxy dimethymethylsilane, DTDS) were reported. The ormosils connecting with C 60 possessed good flexibility and mechanical strength. BET experiment showed that these materials have quite small pore. The compound can be polished on the machine. By using a Nd∶YAG laser with 10 ns pulse duration and 532 nm wavelength, the optical limiting behavior of C 60 connecting with gel net was measured and demonstrated.
