Analysis of organophosphate–Zn metalloporphyrin interactions via UV–vis spectroscopy and molecular modeling

Optical, thermal, and magnetic properties of a microporous fluorinated iron phosphate: (H3O)2[Fe4(H2O)2F4(PO4)2(HPO4)2](H2O)

“…This spectrum shows a very intense band around 250 nm in the visible range which is a characteristic of the charge transfer property between atoms O (2p), Fe (3d) and/or F (2p), and Fe (3d). The spectrum also shows three peaks around 413, 518, and 715 nm which correspond to the d‐d electronic transitions of the iron metal [22].…”

Highly Sensitive Detection of Organophosphorus Pesticides Using 5,10,15,20-Tetrakis(4-hydroxyphenyl)porphyrin

“…The Soret band at 415 nm was red-shifted to 436 nm, and the broadened Q band appeared at 649 nm. Several research groups [19][20][21] reported that inter-molecular complex formation of porphyrin and dimethyl methylphosphonate (DMMP) occurred, which is an OP model compound, revealed by UV-visible absorption spectroscopy.…”
