Evaluation of Planar- and Bowl-Shaped Metallophosphaporphyrins. Inclusion of Steric Effects in P4-Metalloporphyrins Counterparts

Corannulene, C20H10, experience a bowl-to-bowl inversion through planar conformation. The replacement of the N4-kernel in metalloporphyrins (MN4) to P4, leading to metallophosphaporphyrins (MP4), introduces steric effects resulting a bowl-like MP4 counter
