Abstract :
A novel material of porphyrin functionalized Single-walled Nanotubes was employed on optical property research, aimed to DMMP detection, a simulant to Sarin. The composites were synthesis by condensation Zn-Tetraphenylporphyrin and bonding on SWNTs with non-covalent methods. The results were well characterized with TEM, AFM, as well as UV-visible measurements, demonstrated the diameter of nanotubes we used was estimated to range ~0.9-1.5nm, and the existence of nano-composites. It proved that with using porphyrin-functionalized single-walled carbon nanotubes in DMF solution, the materials were reversible and capable of detecting DMMP (Sigma, 97%) at 9 ppb levels by UV-visible measurements.
