Azobenzene-functionalized nanotubes recognized and attached onto well-defined complementary regions of thiolated alpha-CD SAM/Au substrates via host-guest molecular recognition. The binding between the azobenzene nanotubes and the alpha-CD SAM/Au substrates was controlled by UV irradiation. The light-induced attachment-detachment of the azobenzene nanotubes on the alpha-CD SAMs was reversible. Some of the nanotubes were capable of interconnecting two Au substrates. This smart building block may be applied to build photoactive nanometer-sized mechanical switches in electronics.
通过主客体分子识别，偶氮苯功能化纳米管能够识别并附着在硫醇化α-环糊精自组装单分子膜/金基底的特定互补区域上。偶氮苯纳米管与α-环糊精自组装单分子膜/金基底之间的结合通过紫外线照射来控制。偶氮苯纳米管在α-环糊精自组装单分子膜上的光诱导附着-分离是可逆的。一些纳米管能够连接两个金基底。这种智能构建模块可应用于电子学中构建光活性纳米尺寸的机械开关。
