Magnetic susceptibility and EPR changes caused by grinding of samples was written by More, K. M.;Eaton, G. R.;Eaton, S. S.. And the article was included in Journal of Magnetic Resonance (1969-1992) in 1980.Related Products of 57412-08-5 The following contents are mentioned in the article:
EPR signals were observed in 4 metal-free porphyrins. The intensity of the EPR signal increased upon grinding the sample, and then decreased upon evacuation of the sample. The lineshape of the EPR signal and the magnetic susceptibility off Cu porphyrins changed when the samples were ground. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Related Products of 57412-08-5).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Attachment of the ligand to the metal may be through a single atom, in which case it is called a monodentate ligand, or through two or more atoms, in which case it is called a didentate or polydentate ligand. And they often provide a convenient approach to fine-tuning the performance of known catalysts.Related Products of 57412-08-5
