Controlling the growth of low dimension nanostructures of an iridium complex

Controlling the fabrication of the nanowire–nanotube junctions of a dichloro-bridged dimeric iridium complex of 2-phenylpyridine (IPPC) has been achieved by a facile template method. IPPC nanowire–nanotube junctions were prepared at 15 °C, and IPPC nanotubes could be formed by increasing the temperature. It is interesting that IPPC solid nanowires were produced when the temperature decreased to 0 °C. The results show that temperature is a key factor for controlling the process of growth. The emission of the IPPC nanostructures showed a blue shift and a stronger intensity in comparison to IPPC bulk materials.
