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.
