The integration of organic and inorganic building blocks into novel nanohybrids is an important tool to exploit innovative materials with desirable functionalities. For this purpose, carbon nanotube--nanoparticle nanoarchitectures are intensively studied. We report here an efficient noncovalent chemical route to density-controllably and uniformly assemble single-walled carbon nanotubes with CdS nanoparticles. The methodology not only promises the resulting hybrids will be solution-processable but also endows the hybrids with distinct optoelectronic properties including tunable photoresponse mediated by amine molecules. On the basis of these merits, reliable thin-film photoswitches and light-driven chemical sensors are demonstrated, which highlights the potential of tailored hybrids in the development of new tunable optoelectronic devices and sensors.
将有机和无机构建块集成到新型纳米杂化物中是开发具有理想功能的创新材料的重要工具。为此，碳纳米管-纳米颗粒纳米结构受到了广泛的研究。在这里，我们报告了一种高效的非共价化学方法，可以可控地和均匀地将单壁碳纳米管与 CdS 纳米颗粒组装在一起。该方法不仅有望使所得杂化物可溶液处理，而且还赋予了杂化物独特的光电性能，包括通过胺分子介导的可调光电响应。基于这些优点，可靠的薄膜光开关和光驱动化学传感器得到了演示，这凸显了定制杂化物在开发新型可调谐光电设备和传感器方面的潜力。
