LOPEZ B, Rosa  y  LOEB L., Bárbara. Tuning the Excited States in -fac--[Re(X2dppz)(CO)3(L)]: Intraligand, Charge Transfer or both?. J. Chil. Chem. Soc. [online]. 2004, vol.49, n.1, pp. 83-87. ISSN 0717-9707.  doi: 10.4067/S0717-97072004000100014.

Excited state lifetime measurements - emission, emission lifetime and Resonance Raman - have been conducted on the series -fac--[Re(X₂dppz)(CO)₃(L)]^0,+ (L = Cl^-, 4-ethylpyridine (4-Etpy), 4,4´-bipyridine (4,4´-bpy)), with the X₂dppz substituted dipyrido[3,2-a:2',3'-c]phenazine ligands (X = CH₃ and Cl). The results are consistent with closely lying excited states, with pp* lowest, but MLCT contributing significantly to excited state lifetimes for the neutral complexes. -fac--[Re(Cl₂dppz)(CO)₃Cl] appears to undergo a crossover from lowest pp* to lowest MLCT through the glass to fluid transition
