    • We note that the standard explanation of a drop in energy and contribution of charge-transfer states to nonradiative decay does not play a significant role (if any) in these free-base porphyrins. In particular, the only possible charge-transfer states involve the macrocycle and the peripheral meso-phenyl rings, and our calculations suggest that these states are not sufficiently low in energy for our compounds as well as for the related planar porphyrins. Such additional states did not appear also in case of a rotation of the phenyl substituents toward their coplanarity with the "porphyrin plane".
