1Test of Electron Delocalization Effects on Water-Proton Spin-Lattice Relaxation by Bromination of [Tetrakis(4-sulfonatopheny)porphine]manganese.

Bryant LH Jr1, Hodges MW, Bryant RG.

Inorg Chem. 1999 Mar 8;38(5):1002-1005.

The potential value of electron spin delocalization as a means for substantially increasing the ability of a paramagnetic metal complex to induce nuclear spin relaxation of water protons has been examined by covalent attachment of bromine atoms in the beta-pyrrole positions of the [5,10,15,20-tetrakis(4-sulfonatophenyl)-21H,23H-porphine]manganese complexes[Mn(III)TPPS](3)(-) and [Mn(II)TPPS].(4)(-) The water-proton spin-lattice relaxivities are reported as a function of magnetic field strength for the brominated and nonbrominated metalloporphyrins over the range of magnetic field strengths corresponding to proton Larmor frequencies between 0.
