摘要
通过胶体热注射法成功合成了具有"生菜"形貌的硫化铜微米结构。这些"生菜"形貌的硫化铜微米结构由硫化铜纳米片通过自组装形成,而这些纳米片实际上又是由硫化铜纳米球组成。该形貌硫化铜结构的形成与反应物用量以及反应温度有关,同时我们还进一步探究了其形成过程及机理。该硫化铜微米结构具有大的比表面积,同时具有油溶性的特点。基于粒子的这两种特性,其可以很好地吸附具有光响应性的有机分子:螺吡喃分子。将吸附了螺吡喃分子的硫化铜溶液旋涂在商业化的阳极氧化铝表面,成功构筑了阳极氧化铝-硫化铜/螺吡喃异质纳米通道。该异质纳米通道在紫外可见光的相互转换下,具有很好的开关性质且具有可循环性以及稳定性。
Lettuce-like Cu_xS micron particles were successfully prepared by a colloidal hot-injection method. A probably underlying mechanism behind the formation of lettuce architecture was tentatively proposed via monitoring the evolution process. These particles were formed via the self-assembly of the nanosheets as the basic building blocks. These lettuce-like Cu_xS particles are hydrophobic and simultaneously possess a high surface area which can readily absorb the light-responsive 1,3,3-trimethylindolino-6'-nitrobenzopyrylospiran(Spiro) molecules. Finally, the AAO-Cu_xS/Spiro heterogeneous nanochannels are constructed by spin-coating the pre-prepared Cu_xS particles loaded with Spiro onto the commercially available anodic alumina(AAO) substrate. The nanochannel exhibits regulated ionic transport property with good responsive switchability and stability.
