  • Title: pH-dependent photophysical behavior of rhenium complexes containing hydroxypyridine ligands.
    Author: Bare WD, Mack NH, Demas JN, Degraff BA.
    Journal: Appl Spectrosc; 2004 Sep; 58(9):1093-100. PubMed ID: 15479526.
    Abstract:
    Data related to the pH-dependent photophysics of a class of rhenium complexes containing the hydroxypyridine ligand are presented. Data include ground-state pK(a) values, emission energies, and lifetimes. The complexes all have ground-state pK(a) values near 7.0 and exhibit a dramatic change in emission intensity near this pH. The lifetimes of these complexes, however, are constant over this pH range. A model is presented to account for the observed photophysical behavior. The pH-dependent emission properties of these species make them good candidates for luminescence-based pH probes, especially in the environmental and biomedical fields.
