| dc.description.abstract | The photophysical properties of [Re(CO)3(dppz)(py)]+ (dppz = dipyrido-[3,2-a:2 ,3 -c] phenazine) (1)
and its 11,12 substituted derivatives [Re(CO)3(dppzMe2)(py)]+ (2) and [Re(CO)3(dppzF2)(py)]+ (3) have
been examined in organic and aqueous environments using phosphorescence and picosecond transient
visible and infrared absorption spectroscopic methods. The roles of the intraligand IL(p?p*) and
metal-to-ligand charge transfer MLCT(phz) excited states are evaluated and used to explain the major
effect of difluoro-substitution, which is particularly remarkable in water, where the excited state of
[Re(CO)3(dppzF2)(py)]+ (3) is strongly quenched. | en |
