Abstract EN
The self-assembly approach has been widely adopted in the effort to design and prepare functional materials.
Herein, we report the synthesis and optical properties of metalloporphyrin nanoparticles.
Nanoscaled particles of 5,10,15,20-tetraphenylporphyrin manganese (MnTPP) and 5,10,15,20-tetraphenylporphyrin indium (InTPP) were produced in the water/dimethylsulfoxide (DMSO) mixed solution by self-assembly approach.
The absorbance intensity at the characteristic peak of the monomeric and nanoscaled metalloporphyrins decreased when they interact with dimethylmethylphosphonate (DMMP).
Detection limits of MnTPP and InTPP nanoparticles to DMMP were 10−9 and 10−10 L/L, respectively, and detection limits of monomeric MnTPP and InTPP to DMMP were 10−6 and 10−7 L/L, respectively.
Density functional theory (DFT) calculations on MnTPP and InTPP with DMMP as axial ligands had been performed in the B3LYP/6-31g (d) approximation.
Their optimized geometries and binding energies were found to depend very strongly on the central metal ion, and InTPP was more sensitive for DMMP detection in contract to MnTPP.
All the experimental and theoretical results demonstrated that nanoscaled metalloporphyrin have potential prospects in determination for public safety.
