The synthesis and photophysical properties of a series of new Re(I)-carbonyl diimine complexes are reported. The ligand is based on a 1,8-naphthalimide that was covalently attached to a 1,10-phenanthroline. The energy levels of the ligand have been modified through the addition of electron donating/withdrawing functional groups at the 4 position of the naphthalimide. Since these bichromophore systems have been found to exhibit “ping-pong” energy transfer, the modification of only the ligand centered excited state changes the excited state equilibrium, and thus the overall energetics of the system.
