摘要
作为一类重要的多功能性化合物,卟啉类分子的可控组装及其组装体先进性能的调控引起了诸多研究者的兴趣。一方面,这可以为认识分子间pi-pi堆积作用与其他非共价键相互作用的协同性规律提供丰富科学信息。另一方面,这有助于构筑先进光电功能材料并为揭示材料中电子的转移规律提供科学平台。近年来[1],我们以油/水体系为组装/构筑介质,在表面活性剂的调控下研究了吡啶基卟啉类化合物的可控组装,并基于此构筑了在光催化、气体传感等方面的先进功能体系。同时,我们将该组装策略成功地应用到了其他若干种卟啉类化合物乃至其他功能pi体系化合物的可控组装上,基于此诠释了目标卟啉分子结构、组装体结构、组装体光催化性能等三者之间的内在关联。进一步,利用CTAB,CTAC表面活性剂溶液中存在卤素离子的特征,我们将该油/水介质中的可控组装手段成功地应用到了Ag/AgX(X=Cl,Br)无机纳米结构的可控构筑上,实现了这些结构作为表面等离子体光催化剂在光催化降解有机污染物方面催化性能的调控。
In this talk, we will present our recent progresses on advanced functional optoelectronic nanomaterials, which are constructed via an oil-in-water-mediated surfactant-assisted assembly protocol. The following issues will be discussed:(i) controllable fabrication of porphyrin nanostructures and their tunable advanced functions with regard to high-performance photocatalysts and qualified nanoelectronic gas sensors;(ii) Ag/AgX-based visible-light-driven plasmonic photocatalysts by taking the advantage of the existence of halide anions in the aqueous/oil solution of CTAB or CTAC surfactants, wherein CTAB or CTAC plays a role of halide source and a role of tuning the structure of Ag/Ag X. Our work indicates that oil/water system mediated surfactant-assisted assembly might be a facile yet efficient protocol for controllable assembly and tunable functions.
