摘要：

通过自组装方法制备了一种卟啉材料,并通过调节溶液pH值实现了对其形貌的可控。当pH值较低时形成卟啉棒状结构;当pH值较高时形成卟啉叶片状结构。利用紫外、红外和X衍射仪等多种表征方法对其结构和性质进行了表征。结果表明,在无机酸的作用下,卟啉分子通过π-π、静电作用形成一维结构的J-聚集体;当pH值增加时,氢键的作用占主要作用形成二维片状结构。将此卟啉棒状材料构筑微纳米器件,测试其光电性能,表明对可见光有很好的响应。这种具有光电响应的卟啉材料有望成为微纳电子器件的光电元件。

Abstract:

Various porphyrin-containing nanostructures were facilely synthesized by self-assembly technology via modulations of the pH of mixture solution. At low pH, one-dimensional bar is formed, and at high pH, two-dimensional lamellar structure appears. These nanostructures were analyzed by UV-Vis, IR and XRD. One dimensional J-aggregates is formed at low pH through the packing of porphyrin molecules by π-π, and electrostatic interactions. As the pH increases, hydrogen bond plays a key role to switch the porphyrin aggregates into two-dimensional sheets. Photoelectric property test shows a good response of the porphyrin nano-rods to the visible light. This kind of porphyrin nano materials with photoelectric response is expected to be a photoelectric element in electronic devices.
