Abstract: Abstract Gd(III)-porphyrins are promising phosphorescent materials that are widely available and inexpensive compared to the most widely used phosphorescent materials (e.g., Pt(II)- and Pd(II)-porphyrins). However, Gd(III)-porphyrins are generally unstable in aqueous solutions, which limits their… read more here.

Abstract: Iron(II/III)porphyrin/cyclodextrin inclusion complexes serve as hemoprotein models in vivo. Here we showed the iron(III)porphyrin complex to be spontaneously reduced to its iron(II) state in mouse circulation. The reduced complex bound endogenous CO from carboxyhemoglobin, which… read more here.
