A direct correlation of the rate of energy transfer in bridged bis‐porphyrins (an example of an phenanthroline‐bridged bis‐porphyrin is shown) with the interchromophore distance is indicated from time‐resolved fluorescence measurements. The presence of several starting conformations is also revealed.
