WebSubporphyrin is a ring-contracted porphyrin congener consisting of three pyrrolic subunits domed in a C3 symmetric bowl arrangement. Subporphyrin had long been elusive until … WebSubporphyrin free bases exhibit curved bowl-like structures and distinct 14π-aromaticity. Steady-state and time-resolved spectroscopy revealed that the excited-state behaviors of the subporphyrin free bases are comparable with those of the corresponding B III subporphyrins. Rotational relaxation processes in the excited states have been ...

Web30 Jul 2024 · A π-extended “earring” subporphyrin 3 was synthesized from β,β′-diiodosubporphyrin and diboryltripyrrane via a Suzuki–Miyaura coupling and following oxidation. Its Pd complex 3Pd was also synthesized and both of the compounds were fully characterized by 1 H NMR, MS and X-ray single crystal diffraction. Web4 Nov 2013 · The dimer exhibits a largely perturbed absorption spectrum, a redshifted and enhanced fluorescence spectrum, higher oxidation potentials with a large potential difference between the first and second oxidation waves, and a long-lived large anisotropy of S 1 state, which show the effective conjugative interactions of the two subporphyrin units … dragoon changes ff14
