Porphyrin skeletal structure

Fic. 2. Porphyrin skeletal structure and metalloporphyrins found in petroleum (a) por-phine, (b) DPEP, (c) etioporphyrin, (d) Rhodo-DPEP, (e) Di-DPEP, (f) Rhodo-Etio. [Pg.102]

No ligand centered reduction has been observed in a cathodic region up to — 2.0 V (vs SCE) the HOMO-LUMO energy separation in corrole resulted then to be larger than 3.3 V, i.e. much greater than that present in porphyrins. This is consistent with the lower skeletal symmetry of the corrole structure with respect to porphyrin which is expected to increase the separation between HOMO and LUMO [46]. [Pg.109]
