    Tuning the excited states in fac-[Re(X2dppz)(CO)3(L)]
    (2004) López, R; Loeb, B; Striplin, D; Devenney, M; Omberg, K; Meyer, TJ
    Excited state lifetime measurements - emission, emission lifetime and Resonance Raman - have been conducted on the series fac-[Re(X(2)dppz)(CO)(3)(L)](0,+) (L = Cl-, 4-ethylpyridine (4-Etpy), 4,4'-bipyridine (4,4'-bpy)), with the X(2)dppz substituted dipyrido[3,2-a:2',3'-c] phenazine ligands (X = CH3 and Cl). The results are consistent with closely lying excited states, with pipi* lowest, but MLCT contributing significantly to excited state lifetimes for the neutral complexes. fac-[Re(Cl(2)dppz)(CO)(3)Cl] appears to undergo a crossover from lowest pipi* to lowest MLCT through the glass to fluid transition.
