What does it take to induce equilibrium in bidirectional energy transfers?

Abstract

Two dyads built with a co-facial slipped bis(zinc(II)porphyrin), a free base and a bridge, [Zn2]–bridge–[Fb] (bridge = C6H4C[triple bond, length as m-dash]C, 1 and C6H4C[triple bond, length as m-dash]CC6H4, 2), exhibit S1 energy equilibrium [Zn2]* ↔ [Fb]* at 298 K, an extremely rare situation, which depends on the degree of MO coupling between the units. At 77 K, 2 becomes bi-directional due to the two large C6H4–[Zn2] and C6H4–[Fb] dihedral angles.
